I ran one about 4 yrs ago. Edelbrock has come out with a manifold to make the fuel distribution better, but the down side is the valve train. We geared it to run at a max of 5400 RPM. You will need some tall gears if you intend to run a larger track. We were going to try and retro fit a big block dodge shaft rocker system to the pedalstal system of the cadilac. Never got around to it, but my partner was able to fabricate aluminum spacers to utilize small block chevy valve springs and the stock cadillac valves. Get the valve train fixed and it would be a good combination. It was about 180 lbs heavier (if my memory is correct). You will also have to custom fabricate a set of headers. It is a huge pain and you have the weight penalty. I'd stay with a Chevy. Just my opinion.

Chad, by the way what type of tranny-setup did you run with the cadi ?

We ran a chevy powerglide. My partner fabricated the drive flange on the back of the crank and used the engine mid plate to properly locate the tranny with the motor.

MY EXPERIENCES WITH 500'S ARE THAT THEY MAKE THE BEST POWER AT IDLE TO 3500 RPM'S AND AFTER THAT YOUR LOOKING AT A NICE BIG WHOLE IN THE BLOCK WITH A ROD POKING OUT THE SIDE. THEY CAN RUN HIGHER THAN THAT IF YOU EXTENSIVELLY MODIFY THEM BUT I WOULD STAY WITH THE CHEVY MOTOR OR A 455 PONTIAC BECAUSE IT DOESN'T WAY MUCH MORE THAN A 350 CHEVY AND MORE HORSE POWER THAN ANY OF THE OTHER BIG BLOCKS. I LIKE THE DODGE ROCKER ARM MOUNT TRICK.

You might want to check your library and see if they have a copy of "Stock Car" magazine, Feb 1991 page 92 for an article titled "Dirt Track Cadillac".

Concerning the weight of various engines; There is a book titled "Race Car Fabrication and Preparation" by Steve Smith of Steve Smith autosports (I think there is a web page

On page 6 of my copy there is a chart of many engines giving 7 different outside measurements of each engine. Also, it gives the weight of the engines.

Some of them are:
Buick V6 370lbs, Ford V8 351ci 460lbs,
Chevy V8 350/400ci 550lbs
Buick V8 455ci 600lbs
Pontiac V8 455ci 640lbs
Chevy V8 454ci 625lbs
Cadillac V8 500ci 600lbs
...and many more.

There is a guy that runs a caddy motor in his modified with us, and he will pull anyone out of the corner, but cant run with us at the end of the sraight. This was the first person i have seen run a caddy, and i was very impressed!!

With a 4000 rpm red line, its gonna be pretty easy to have too much gear. What I've read is that a 500 with "little modification" isn't musch good a "little" over 4000 rpm. Tons of power and torque, realtively light, but you're gonna pay for that at the end of the straightaway when a piston leaves the building.

Banshee, what did you do for an oil pan? Build your own or find someone who makes a circle track cad pan. Larry Kruzick used to supply them but he sold the business and the new people dont have them anymore.
