mine would have to be the 440ci MoPar
BowTie Girl; I like the big old caddy engines too, I've got a great site for you.www Maximum Torque Specialties. That engine your talking about has 400HP and 550 foot pounds of torque. More then most of the big diesel pick up's today.

Vegas I know Maximum Torque specialties quit well. I have thier Cat and have order quite a few things from them, including the great howtoo book. I like the fact that the are only 50lb heavier than a SB bowtie. most boyz don't realize that makes it almost 100lbs light than a rat. The weekness is in the valve train but can be easily fixed.
BowTie Girl; Yep I got the cat too. And they have that new rocker set up now, so like you said it can be fixed. Plus they have the short A.C. compressor so you can put on a after market intake and they have the fuel injection set up too. And they have aluminum Valve cover now not the adapters.

I will stick with a 1911 edelbrock qjet. Best damn carberator. I have the 750 on my pontiac. I love it. When it comes to cars. I am not the average home maker! LOL
How about that LT5 (from the ZR1)? If they were easier to get, I bet we would see some pretty gnarly versions of the motor running around, but 405 hp is still nothing to turn your nose at. It's aluminum too.
The Gen 3 in the new GTo is stock at 350hp and is aluminum. The Caddy is not aluminum. It is a steel block with an extremly high nickle content. Thin castings so they tend to run hotter than the norm. can't bore much either. But, then the nickle also wears less so there is really not much need. My block came from a 71 Eldo with over 100k. My finger nail cannot snag any ring ridge. I guess I won't get much more techical. I don't want anyone to think I was full of lunch meat. LOL But If you don't believe me you can do the research yourself.
BowTie Girl:Right now I have an 800 Rodchester on my 472 Caddy but I want to get one of the Predator carburators. Streets swears by them and they go from 390 cfm's to 930 cfm's. Its the only thing that Streets runs on his bad *@# cars, so I think I'm going to try one out. I do have a Holly 750 on my 351 Cleveland. But you have problems with the power valves. If you want to know more about the Predator you'll have to talk to Streets he can explain it better in detail than I can.
Vegas
Holley sales a powevalve conversion kit to fix that blow out problem. I think I will stick with what I know. I have a carberator guerue that has told me that predators do like the street well. If I cannot have my Qjet I will settle for an AFB. I don't like Holleys either. To much to fiddle with. A Qjet either work or it don't. If it don't throw a kit in it and it lives! HP books puts aout a great book on Rochesters! Check it out!
BowTie Girl: I used to run the AFB carters on my big block Dodges and they were a good carburator too, but these Predators don't have anything to mess with, real easy to rebuild, and they work off vacuum and will only use as much fuel as it needs. They're pretty neat actually. Just talk to Streets...and check it out! They dont spend a lot of money to advertise. Thats why you dont see them a lot, but a lot of the big name mud trucks run them to power their engines.
Vegas
DO you have room for a manifold? and EDE 2115 will give almost 25 hp on the 500 because the original designe was poor. I did not know if the 472 was the same. I just know that stock manifild flows uphill.
Ive yet to hear anyone even mention the classic Stromberg 97 two barrel. As for favorite all time motor how about a late model Mercury flathead with a hilborn setup and an Ardun ohv conversion.
I hope I am being more help than a pest. I see that I am posting a lot.
I like many motors but it depends on what there in. I'm putting a 350 with dual predators and progressive linkage in my 83' Mercedes Benz, and a Th200 trans. If I had a Mopar I would want a 440 6 pack and a torqflight 727. If I had a Caddy I would want a 500 caddy.
BowTie Girl: The 472/500 blocks are basically the same everything fits but, for me to put a 500 crank into my 472 I would have to notch the bottom of my cylinders..otherwise than that its all the same.
Vegas
my 500 is going into my 48 chevy 2dr. They will go where a rat will. And think I think that the powerplant of choice tells a lot about a person, in the Hot rod world!
Gotta have an ELEPHANT motor some day.
As for fond past "loves", a 308, Twin H, Hornet.:3dSMILE:
Also Vegas, heads will swap if you like lots of compression. The 500 is 4.25 bore x 4.25 stroke. A square engine!
well motor of choice and picking a motor that can help destinguish a certian car is something else, but as to motors to set between the rails of certain vehs are endless, me myself prefer a 440ci MoPar, but i dont think that it would look good in a 36 dodge cpe. or the same motor in a 50 ford shoe box.
Actually Knuckles, I think a Blown 440 would be awsome and speak wonders for a 36 Dodge cpe. It is all how you build the car around the heart!
very true, but i think a 354 double rocker or 421 pontiac with 8 stroms would look killer also

very nice, i likes the rim choice it compliments the cara very well
Jonney
Thanks. That is my Pontiac. 400/400 combo.
i need to get some of my pics loaded onto my pc so i can postem here.. but thats a nice pontiac you dont see many of those on the road
I am even having problems finding part. Let me knwo if you know where I can look. I have a small list
i live out in the boonies now in NC I will keep my eye out i have seen a lot of not to commonly seen cars out here since I have moved from CA.
If you can put gas in it and it sounds good I am happy with most engines but my fav was a 70 pontiac 455 shot .060 over with 6x heads an edelbrock torker intake and cam and a holley 750 dp on top of it in a 73 pontiac grandam I could lay down rubber at 60 mph=fun
btw bowtiegirl that 71 pontiac is sweet I am almost bought one like it accept maroon kicking myself I didn't also had a 455 swap done to it.
BowTie Girl; I have a 1969 472 with 10.5 to 1 compression, this motor is rated at 375HP and 525 foot pounds of torque. In 68 & 69 was highest compression and these are the best heads to use going over 5500rpm's or for high performance in the 500 or 472. Pre 72 heads have a 72cc chamber after 72 they went to a 120cc chamber in the heads. And after 1969 because of the piston change the compression droped to 10 to 1. Now with a few mods I can have more horse power then the 500 and turn more RPM's. There is no better stock head then the one I have on my 472 right now.
Vegas:D
PS Nice car
If this is still about which engine we like, my choice is, of course, the 455 olds. Lots of torque, and they have a very strong bottom end, Thank you, good night.
Vegas you need that book on building you moster from Maximum Torque Specialties!
ok. I am sharp. but not perfect. I bow down once again to the great male intelect! LOL
Techinspector; Could you please try to explain to her about compression..and combustion chamber sizes, and their relativity to horsepower? 1970 was the best year for the 500, after that the compression ratio dropped because of piston changes and in 1972 they changed the head design to a 120cc from a 72cc. The 500/472 heads were exactly the same...I don't know how else to explain this to her, I don't think she understands, maybe she needs a compression and horsepower chart. I'm banging myself in the head here.
Vegas**) :CRY: :(
No need to hurt youself, Hun. I don't quite understand wthe whys and what fors, but I do know that the 72CC heads have the best compression for the earlier blocks. According to my casting #s I have the 72cc heads. Also got that info from Max Torque. I also know that the earlier 500s had no drainage in the lifter valley. Already corrected on mine. I do know that the highest HP rating for my Monster motor was in 1971 were as after the Epa got their noses in it as wel as GM changed the way they rated horsepower. But I could always use more schoolin. That is what the Forums are here for, sharing right?
BowTie Girl: Here's a website for you to check with the charts on torque and horsepower as to different years of the 500/472 engines. You're right about this site, you can find a lot of information. And the drainage in the lifter valley wasn't a big deal in the earlier years because it was only paper thin casting that had to be knocked out or taken a die grinder to. In 1971, the horsepower dropped because of the piston change...went from 10 to 1 down to 8.5 to 1. And only 535 ft. lbs. of torque, and 365 horsepower..which my 1969 472 has 525 ft. lbs. of torque and 375 horsepower. So there isn't much difference. 1970 was the best year for the 500 by far.

thanks. can never have too much info. I knew there was a reason I found this site! LOL
BowTie Girl; I have a question now. Have you been scaning the photo's of your cars and then sending them thru. If so please tell me how you are doing that, because Ive been trying to post some pictures I have. but don't know how to make my scane pictures JPeg, and please tell me the program you are using because I might have to get a differant Program. Thanks
Vegas :)
I know how, scan them in, save them and then use ms paint ( commonly paint ) and save it as a jpeg, it will let u do it there. Hope this helps Vara4.
Matt167; thanks for the info. I have another question for you! First the 727 torque flight is a good choice. But why the 440 engine.
