so the cam hit the counterweight no they hit on if any on the side of the rods the case of the block will hit before the counterweight would hit the cam. swhanlee28 thanks for the nice comments and my tools have work on fords .i have a customer that hase a pull truck that eats 520+ fords and it a 496 kane needs to get up to speed on the chevys i am not saying you can not make fords run BUT if you think you are going to just run one over a chevy and i have no need to get up to speed on the fords i have work on them and valid technical info swhanlee28 you may want to look at my 1600 +post and read back thru some of them on big block chevys? . 600 hp can be done with stock gm big block stock stuff .new ford info?? i can not keep up with all the new chevys heads that have came out in the last two years so do you think the chevy info i know is old news?? why yes it may be 1965 is when they came out but i have built many over 540+ big block chevys and they had 750to 800 lift cams .oh they look better to. swhanlee28 are you selling your chevy truck?and if it was not for the cheap H beams bbc chevy rods you use and the rod bearings you could not cut down your cranks and do it on the cheap?

i'm a ford man, but ford or chevy can be built to beat each other, its just a matter of resources and ability to build a good engine..... hell down here i've seen mexicans build motors from junk yard parts and have them run better than shop built motors, just because they know how to build engines out of shit....

well i have some good friends i try not to think of them has mexicans only when they call me white eyes i have put stuff together for them that was junk but it runs damn good . i really do not care what make it is you drop some thing off to me and say make it fast i do. I have done alot with not much BUT to get on a soap box and say why some brand as better when they are not is bs i have said this some may not like it but I will not post bs on a post and if you do look out

Just 1 question for now.would u spin a chevy 454 crank to 8,9 or even 10000 rpms? Not aftermarket ,because aftermarket is just that! a callies crank for chevy aint no chevy crank and the same goes for ford.

hmmmmm really do not think i know what you trying to say that it can not be done with stock gm stuff? i have had cast gm cranks go past 6500 and steel stuff go past that.7500. so are you saying that it need to be a callies to go to the 10000 mark?? why would need to go that hi ?? shawnlee28 how many engines have you built ? the crank will fail sometimes from its make up but this has not stop many 7000 rpm big block s from running stock bottom ends. if you need hard proof i can give up phone numbers of many ? callies crank can and do fail but how you build something as more to do with what you buy for parts??? that is to say hi rent engine come a part if you do not know what you are doing. ok maybe i know now ?? are you saying you can do more with a bone stock 460 ford?? NO i think not? get your stock heads setup for adjustable valve train buy all your parts it will be more than a big chevy. so i will try this. for $3000 you can build 540+ ford? ok but are talking all stock stuff. no. and heads? ok a stock 454 over .125 482 or .060 over 468 chevy stock rods two bolt block stock crank steel or cast stock gm heads 781 or049 O ports ok for you ford guys they are not Ho heads . now with the rigth CR and cam 650 hp should not be to hard this is all stock gm parts and not bow tie race parts

Sotck 460 cranks spin to 7500 rpm asll day long. Prep the oem crank and more rpm is possible; I know a truck puller, for example, that spins his motor with stock crank and block to 9600 rpm. During wheel hop, his tach records 10,300 rpm...during a very abusive sled pull, mind you. Just you ty that in a dyno cell with your chebby...but hey, you'd better hope that glass to the control room is bullet proof when the motor grenades. Damn hevy domes GM pistons required to get a decent compresison ratio.

But on the filipside, you pose a notworthy question: What about the rest of us who don't need to spin their motor so high??? Again, Advantage: Ford. We make power across the board, compared to the chebby. We don't need to spin our motors so high...but we can if the need arises.

You mentioned that our engines cost more to set up than the chebbys. Pat, this is outdated, antiquated thinking from those that are out of touch with what is available for Fords today. Did you you that we have over 25 differnet aftermarkedt aluminum heads availabel these days? that's just onc example. Did you know that our passenger car (NOT CJ) iron heads are supporting in excess of 600HP on naturally apsirated 460's? Pushing 800HP on stokers? Can chebby say this? the 429/460 heads intake port architechure is the best of the era, and the lackluster exhaust port has had its secrets unlock, thanks to flow benches and pioneering open-minded engine builders.

And yes, I am taling about stock, oem parts and that's what is so fantastic about these engines. you should really keep an open mind and look into them a little more.

well chevys are droping left and rigth think again ? no one builds heads for chevys ?? you are way off .there is just as many companies out there making chevy heads or more. this need to get personal ? if so ok but if so let me know. i think you can read? there is no bolts at top at 12 .oo or 6 .oo on fords.good place to put some if you could.so at this point bigger bolts to make up for it?? chevys do not need the big bolts there is a better clamping force. hmm more head bolts around a hole sounds good to me. i will add over 10 to 1 CR and 10pounds of boost and over with a1017 felpro head gasket with NO head studs gm bolts . you tell me. i can not drop a 1/2 stroke cranks in an stock block HMMMM are you telling ME i think not. how many cranks have you put in chevys ? i bet i have put more big block cranks in than you.oh and they do a good job staying in . but lets not dwell on that.there is sometimes a small bit of grinding this has to do more with the rods you use. saying the counterweights hit the cam .more bs . a stock pan??you say stock pan will work on you fords? yes right .hmm yes a big crank and no oil scrapers or oil control ?the shelf type stock milodon pan fit s a chevy with a 1/2 stroke . yes a chevy can get 600hp out of it with stock parts and rpms??? you want to laid down some money ?????? i have had many big block run past 7500 but why? the last one made 765 tq and 850 hp below 6500 and likes to whip on your fords . i see you like to take what you like out of context?someone said you need a caillies crank to go to 10.000 WHY no power up there you do not need to go that hi but they can.i bet all your ford s you build you run them at 10000 all the time ?if os tell me what valve springs you use there are the same that well fit in a bb chevy head . if you are going to reprint and get it rigth . on the chevy blocks sorry to tell you but there are 800 hp+ out there with stock blocks i would not do it but it has been done . the hi nickel blocks can take a lot . for the resharping the cutter? well the bore is bigger so you may have to resharping it more.i touch up mine on every hole . but can you tell me that your block is more ductile than hi nickel so your are telling me it will not give just break? the chevy is 50 years old ?? well 1965? for the 396 ? last time i check chevy did come up with the canted heads first. i am sure if i am not rigth you will let me know? and it will cost more to build your ford. hear are some prices fluidampr chevybb $369.95 ford $396.95 heads dartsBBc 2299.fords edelbrock $2619.so just to build your fords it well cost more . but can you get more cid out of it you may. but you are saying it is cheaper to build as a 460 than a chevyNO cams more money. lifter more money.on this point lifters bore size do not tell all the drag cars and street cars with roller in them with that the lifter size is no good? some of them have 800 lift roller cams in themand there is more 460 than 454 ? and 427tall deck truck blocks ? ok just truck blocks ? i would not bet on this it 1968to1990+ may be close but i would say chevy was still using this block in mark 5 form. any one can read this can see the cost for ford parts in jeg.s or summit . make your mind up. oh on the pistons ? 475 cid chevy je grams 659 10.8 cr on ford 477cid 674 grams you can get to 12to1 with this piston so let be fare the chevy 14.7cr 475 cid 654 grams so the chevy is heavy?no. but lets not for get them big rods they are heavy more then the 10 grams? this may be hard to say has alot to do with the rod and i get more than one point more so cr i would say this is a draw ? no .so your ford has some hole punch thru it yes

Well, Pat. A stock bore 460 with a solid lifter cam and a single four barrell on E-85 puts 500 horse to the ground... All brand new pieces with Victor heads, total cost of $7400..... This is on a chassis dyno, not wishing and guessing on a virtual dyno. Maybe you can do better with a chebbie using the same type of pistons and cam and the same cubes.... I don't know. I like my Ford's, but I realize everyone has good engines now... They are all pretty equal in performance and price..... BTW, BB Ford aluminum heads can be bought for a lot less then $2600....


Here, just the first place I checked on head prices. FMS-M-6049-SCJA Ford Racing Super Cobra Jet Cylinder Heads
Cylinder Head, Super Cobra Jet, Aluminum, Assembled, 72cc Chamber, 290cc Intake Runner, Ford, 429/ 460, Each
Monday $999.95

Regular price at Summit. Looks like $2,000 brings home a good pair of heads.

well i like my chevys and the engine i talk about was on a real not some wish and hope bs and hey i like you ford guys when you drop stuff off for me to fix .i have work on more than one so i do know my machines and tools work on them but the big block chevy is not as bad as Mr kane likes to make it out to be on the heads this was out of comp and yes i do see you can get them for what you said but edl-61669 is 2659.00 out of summit there is cheaper heads for both but was thinking this something close to the dart?bbc to be fair

Well, maybe the chebbie is a good motor. Given my druthers I'll let guys keep all the big blocks and keep learning and prepping for my 4.6 DOHC with the ProCharger..... Saw the car and the dyno sheet on a '99 Mustang, 24 pounds of boost through an intercooler puts a tad over 600 hp to the wheels... And in the 6 speed Mustang logs 26 MPG when driven like a normal car.... I hate to admit it, but technology and $3.00 a gallon gas is turning the big blocks into dinosaurs. And I've dearly loved big block motors for a lot of years!!!!!!! Think I know how Dad felt when the OHV motors made the flatties obsolete.....

yes i have a customer that has a z06 vett that makes 470 at the back wheels it is not a big block but it is fun to drive

Yup, afraid the handwriting is on the wall, Pat. I'm going to jump all over this 4.6 DOHC stuff, I would still like to take the Ranchero to Bonneville someday. Fairly high altitude out there in western Utah so I figure if there isn't any good air, I'll just run the Pro Charger blower and make my own air!!!! Tune the car with a lap top!!!! Who would have ever thunk it?????

Pat,

The first thing I said was that I was not looking for a pissing contest; I really don't have the time. My posts on this subject come purely from my enthusiasm for the 385 Series engine and I wish to enlighten those with an objective mind and are willing to listen...and then make up their mind.

You said just above that I lay things out to be lousy for chebbys, yet I never called them a lousy engine. In fact, one of the first things I stated today was, "both chebby and Ford make a decent engine."

I grew up a Mopar guy, built more than my share of chebby's since they are so abundant, and I hated Fords. I downright hated them, Pat. That is...until I took a 460 apart and really looked at what the stock componentry has to offer. The simplified and superior oiling system, the front mounted dizzy which is driven right next to the timing chain and not the opposite end of the cam (eliminating torsional cam timing offset--ask any chebby drag racer), all the other noteworthy design advantages that I already noted, etc.

Because of your latest reply to my posts from earlier today, I had to go back and re-read what I posted to be sure I wrote what I meant, and I most certainly did. Yet based on your reply, you don't seem to be accurately be comprehending what I am trying to lay out but ijnseasd seem to be putting words into my mouth that I never stated...perhaps because you are reading too fast or maybe just too emotionally involved/chebby biased. You seem to take the forum all too personally and I don't wish to get yours or anyone elses panties all wadded up. I'm moving on as I have much better things to do; just go ahead and keep on thinking what you want and the best of luck to you.

Paul

dave i like any good running engine i know the cost and time i do not like see any thing come apart i am not one of them jackass that like to laugh at someone when a engine come apart that is not me. i like any thing that runs good
