I do think this is the most powerful destroked SB Chevy engine that can be made . It starts out with a 400 block . then a L/J ( 327 Crank ) With it's 3.250 Stroke . Install it in the block using TRW# MS3063P Thick-wall main bearings . And a set of 5.700" L/J Rods . With a set of TRW#L2418F Domed Pistons that will give a C/R of 12.5.1 with 64cc heads . Now you will have a ( 348ci SB ) or with a .030 over-bore a ( 352ci SB ) . ;) COOL The TRW#s can be crossed .
wait and see how many people say it sucks or dont work, im all for it. i wouldnt mind having one if this bbc thing doesnt pan out RING RING <nudge nudge> but anyway....sleep time finally!... 4:58am :eek:
That combo would probably be good in the Rs Dept , but may be down a little in torque. Kinda like a big version of a 302, once the Rs come up it would be a bear. I would try one.

You can always go with the biggest destroker .This is made with the 400 block . And the ( 3.484 ) 350 crank Now you have a ( 372ci ) or .030-over a ( 378ci ) This one will not be down on Torque . I do know a guy that drives a 1962 Corvette with a built 378 and a TH400 and a 9" rear end 430 gear . His car is very streetable and runs high 11s .Quote:

If it is an open class then it is the 14.5 to 1 comp. ratio,along with a 6.125 rods,mech. roller cam etc.
For a bull-ring it is not un-common to use a 6.50 gear or more.
We ran them at about 15.5 - 16:1 on methanol in the late 70's on a high banked bull-ring in the sprinter. Larry Nagel built the engines, don't remember the exact setup but it was 3.48 stroke, long rod and a hi $$$$ piston. Track had a 400 ci limit then, when it went dry slick we would put the final gear ratio at about 6.70:1, set the chassis very soft, feather-foot the throttle, and run on the bottom!!!! If the track pulled any moisture up at all, could do some giant wheelies coming off the turns!!!!!:LOL: :LOL: :LOL: :LOL:Quote:

Nope. No love for them at all. I was just the "hired gun" that drove the car. Later when I was one of the owners, we had an engine shop for a sponsor and he built chebbies for the car..... My preferences had nothing to do with it...Quote:

IMO the engine is the easy part. Buy the right pieces, have a good machinist do the work, bolt it together....No big deal.
What kind of engine are you going to bolt together for that 1982 Camaro ?
Aluminum head 408 Windsor stroker with a C-4 tranny.... It's Jackie's car, she has a bad hip and doesn't like to run around town with a 5 speed anymore..... Otherwise it would have a TKO 5 speed.Quote:

It also has a lot of "unique" sheet metal work, 4 bar rear suspension, coilover/strut front suspension, 6 point cage, custom dash, and a whole bunch of other mods. I build cars with certain parameters in mind and performance, styling, and handling goals planned out long in advance of the build ever starting. My ultimate goal is always to have all the components compliment each other and work together to achieve the goals I established in the planning stage. The 'maro is just a street drive, no big deal. The Ranchero would be most closely described as pro touring, with the objective being 250 mph at Bonneville. We used to have discussion here about building the car to a "theme"..... Doesn't happen much anymore I guess. About half the threads on here anymore are just a re-hash of which cam and heads to put in a sbc....... Nothing wrong with that, I guess. Just hate to see people limit themselves to just an engine, or just the paint, or just anything!!!!!! The entire car and all of it's pieces conveying the same theme and all designed and built to achieve a certain goal is way big fun!!!!!
CarCraft did it around 2000 2001 if you can find it on their site but i read in their magazine they used a 400 block 327 crank and used ford 4.9Liter (300 L6) connecting rods and got like 450hp out of it on pump gasQuote:

That sound like a wild set up . We have some of the 4.9 300 Ford engines at work . In 25 years I may have seen one throw a rod . We call them iron horses . ;)Quote:

That's why I stated as an objective and not as some sort of silly___ claim.... We have about 3 years of (part time) research and 200+ man hours in the project so far. On paper it's close, in the real world it's at least 2 years and $70,000.00 away.
Anyway, it's all for real and sitting in the shop anytime any of you would care to stop by and take a look.....
Here is a photo of the Piston That is needed for the De-stroke 400 build .
Whatever.....
Dave do you really think that Ranchero is a good Car/Truck to build for a high MPH Bonneville build . They may not even let you run some-thing like that . May-be it would be better as a street build . The Camaro would be the better car even with that 408 Ford engine for a Bonneville car . Do some more research ! :HMMM:Quote:

So, whatever was just my way of saying I don't really care to participate in another discussion about your engine.
Well, it's not quite stock anymore, pics in my gallery. We're doing it because it is unique and we want to. Nothing really unique about just another 'maro. And yes, they will let me run it. B-Ville has a class for everything from 100cc motorcycles to jet powered cars. Safety rules are the big issue and I'm quite certain it will meet all of that criteriaQuote:

It's a '67 Ranchero with a 4" chop, window posts laid back 10 degrees from stock, overall length shortened 14", full frame, and a whole lot of other mods in various stages of work. At ride height, the top of the roof is 48" off the ground and the interior has room for a 6' + driver. Next major work will be the suspension (still being designed) and the cage.
No reason to start a build thread, no time to work on it for awhile anyway. I just put pics in my gallery from time to time and leave a note about progress in another thread.... I build the pieces in my spare time and lately I have very little of that......:LOL: :LOL: :LOL: :LOL:
[QUOTE=DennyW]That's fine Dave, It was a entertaining reply though.
There you go with the whining thing. You forgot didn't you ? It's supposed to be: I know he went crying to the moderator, remember ?
That's just what I mean. I'm not whining, are you ? I'm telling you like it is, straight up. So if you would be so kind as to not throw the extras in some of your replies, I would appreciate it. Just trying to get an understanding here. It's clear you don't like me, and that's ok. But you just seem to make an effort to do those things. Thanks for your understanding. :) And yes, this is my last reply to you, I promise.[/QUOT] Are we having a pi$$ing contest ??
Is this going to turn into the same thing as what happened with Richard??
Just remember you are both leaders on this forum and all the things you can teach the younger guy's.:)
Nope. I don't get run off as easy as Tech...Quote:

Pat's monster motor can get that Ranchero there. But not no Found On the Road Dead motor. :LOL: Dave them $1M dollar, 250 MPH rides a few days back look a lot fancier than a Ranchero. Go get 'em. :cool:

But the more we learn about it, the more we find out we have to learn!!!! I sure do love a challenge, though! I'm very fortunate to have some very knowledgeable people involved with me on the project.... The one thing I am definitely sure of is that this is not the kind of project you can just hurry through and hope for the best! Heck, could end up starting the whole thing over with a Torino type body style just to get some of the aero numbers to look a bit more favorable........
BTW, if you have any suggestions or insight on particular problems along your area of expertise that you feel we may encounter, your input would certainly be appreciated!!!! Oh yeah, do you know of anyone who has a wind tunnel we could borrow??????:LOL: :LOL: :LOL: :LOL: :LOL:
go dave!!!
