ok folks, I need some input here. I have got a 4 door nova and cage for $100$. I have a guy that owes me for a transmisson and he said he will give me a cadillac 472 and tranny to pay me off. Would that be to nose heavy for the car? The rules state stock motor would that meen stock motor for that car or just a stock motor? Thanks alot Matt

The stock motor part you would have to check with a track official, but ussually means checvy to chevy and ford to ford. In my opinion, big parts dont work as well as small blocks. The more weight you put in the front end of the car the more you need to put in the rear to get the weight percentages right. Overall, this means a heavier car

Some friends of mine built a cruiser and put in a 430 buick and won the championship that year,some of the motors they ran with were'nt even stock and they would pass 2-3 on the straight,needless to say thay passed a rule for next year chevy-chevy etc. the car was a caprice,the 472 had good power up to 1970 then they fell off due to lower compression,according to a magazine they are high nickel content and one guy said his would roast the tires in his dually with 500,000 miles on the motor!Just keep in mind these are very low rpm motors and anything over 4500 and you are defeating the purpose,the valve springs are so light they can be floated real easy,i'd try it you have nothing to loose but some labor in a motor swap.

i wouldn't try it to heavy and no aftermarket performance parts you'll fight that thing all year long tring to keep it cool and getting the car to turn go to the junk yard and get a 350 to rebuild put about $500 in it and go race'n there is a reason why 95% of us run chevy

The Caddy big blocks aren't suited for oval racing. The have really low red lines and are pretty cheaply built. The have monster low end torque (to get a 2 1/2 ton chunk of steel moving) but not much on the high end.

If its free and its gets you racin, than go for it, but I wouldn't sink much money in this set up. If you do decide to forge ahead, do a search on the ol' net for Caddilac high performance parts. There are a lot more companies than you might expect that make parts for these motors. There's a big market for shoe-horning those engines in Chevelles and other 60's & 70's hot rods.

There is an aftermarket for Caddy motors. Maximum Torque Specialties, and a few others. They get a ton of HP and torque from these engines..they have cams roller valve trains oil pans but plan on spending big$$$$$$ for these goodies..
But as others have said they are heavy and not suited for high RPM use.. Chevy would be cheaper in the long run..
