Well after a couple of days we finally found that the Small Body HEI unit that I had built for the 507" Cadillac just wouldn't rev beyond 4100 w/o missing. This was even after we converted it to a trigger only unit an connected it to an MSD box....something wrong somewhere. Luckily Marty Lane at "Maximum Torque Spealties" loaned me one of their Pro Billet dist and it worked flawlessly.

Keep in mind that this engine was built by me for a street rod, was not a max. horsepower effort, reliability and streetability was my main concern. It has 8.7:1 compression and will run on 87 octane crap gas if needed.

This thing even amazed me on the torque output, one of the pulls it made 489 lbs. ft. @ 3300 rpm. The best dyno pull we had was 535.7 lbs. ft. @ 4200 rpm and 466.7 hp @ 5000 rpm. It idles @ 850 and pulls 11" vac., pulls 13" @ 2000 rpm......the best thing is it doesn't leak a drop....anywhere, HATE leaks!. Here's a couple of pics, I had to highlight the torque power curve graph as the printer was running low on ink. Thats shop owner Earl Snow on the carb....the top red line is the torque....not much of a curve huh. VERY happy with the results........Dave

Gotta love those numbers. This is why I love big cube engines. Hoping for similar numbers out of my 455 olds, but not expecting nearly as great street manners as yours seems to have.

[327NUT]

Thanks....big cubes means you don't have to have a maniac for an engine. The proof on mine will be in the driving....which unfortunarely will be a while till I get this '32 Ford Victoria finished = $$$$$$$

[popo1984]

What were the spec's

[327NUT]

It's a '75 Cadillac, .030, cast pistons, Hastings cast rings, PEP forged cap screw rods, stock 10-10 crank, 230/238 dur. hyd. flat tappet cam, non -adjustable shaft mounted roller rockers, LOTS of work done on home ported/polished heads, larger 2.11/1.77 Pontiac SS valves. "Maximum Torque Specialties" single plane intake with a Quick Fuel Tech. 780 vac. sec. carb. The block and heads were cut approx .030 to achieve an 8.7:1 compression ratio.

The rotating assembly was balanced and the entire engine researched for parts compatability for the application it was to be used for.....and then built with tender loving care.

Congratulations Dave, those are some great numbers! That is one sexy looking Engine, and you will need a neck brace for that Torque-

With that amount of HP and TQ it just shows what can be accomplished with careful assembly and a well thought out combination-great Job and good work!

[popo1984]

Good deal should be fun to drive. can you get a hyd roller set for these

[327NUT]

Thanks 35....now if I can just get the car finished.....and yes you can get all sorts of hipo speed parts for the 425/472/500 Cad including a roller cam. Look at Index, great guys.

[Custom10]

Nice!

Are you gonna run such big primaries on the car headers as the dyno headers? You may actaully pick up even more torx on the bottom end with a bit smaller pipe and longer collectors,,,not that its lacking in any stump busting ability

[327NUT]

Those dyno headers were borrowed from a guy who runs a blown Cad at B'ville. They worked but MAN they were ugly!...the headers I will run in the '32 will be 1 7/8" 4 into 1 due to space limitations. It will have a 3" collector opening and 2 1/2" tubes back through Flowmaster Hushpower II's. There's a young guy in my little hamlet here who just lost his wife, got 2 little kids but he can tig weld beautifully. I'm going to give him the job to help him out.......Yes, I don't think it will be lacking on the torque side.

[Custom10]

Good, sounds like you will both benifit from those custom headers being made up. While your at it might what to ask him to stitch in an extra cross member or two on the chassis

[327NUT]

You know, I already have extra braces made for the rear 4 bar brackets......where they connect up front and at the axle. It's a TCI chassis which is pretty stout but a little extra help won't hurt. The car will only weigh about 2900 lbs. and with 255/65/16 tires it will have limited traction "IF" I get on it. A big set of sticky slicks would be a problem though....not what the car was made for, it's a cruiser
