I was playing with the idea of running an olds engine, has any one tried running them and how did it work? What needs to be done to them to make them competitive in imca or umps.
Thanks, Mike

check out mondello. they have a setup where you use a diesel 350 block and bore it over .250. then you use a forged crank from an old 425 with big block rods and custom pistons. i think it makes a 455 small block or something like that. some drag racers have used them.

Running engines like that are neat but $ for $ the SBC is cheaper and faster.Dont creat more problems for yourself.

gotta agree w racer111 on this

the olds engines have alot of lower end torque but they are not worth a darn unless ya dump a full wallet into them

the caddy engine is a great engine if ya can get a low mileage engine then a freshen is not a whole bunch of $$ but if the engine has a lot of mileage then its gonna cost 2 wallets of $$,but I had 1 in a 4wheel long bed chebby 4x4 and I could hook up to most any 4x4 and make em cry when I was backin them up
1 time I allmost flipped a Slodge Ram

racing is way too cool gave up golf for it

what works in a drag car don't work on a cirlce track. i know alot of cruiser guys that had oiling problems running 350 rockets. like the other mentioned they are big $$$$. think if i wanted to be different i would run a ford instead. as for those caddy motors just to heavy it's very rare you will see a big block in a imca or ump mod. it's just so much easier to make cheap power out of a small block and save the weight

Don't want to step on your toes but the best thing you could do is use that olds motor as a core for something else. Never seen an olds motor that could do anything without $$$$$$$$$$
and More $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$!!!!

I run an off brand engine (Buick) in a modified and it is definately more work. You either need to have a lot of money, build everything yourself, or go with one of the more common engines. It does present some interesting challenges though and is very rewarding when you do beat the establishment. Here's a quick list of stuff we had to make, modify, or find ourselves: Transmission coupler, headers, oil pan, oil pickup, windage tray, motor plate, motor mounts, mounts for all accessories on the front of the engine, pulleys, fuel system, oiling system, and there's probably some more I'm forgetting. Do not take going against the grain lightly. The pluses are, our engine is only 50# heavier than a small chevy, will run with all but the hottest small blocks in nearly stock state of tune, rarely turns over 5500rpm, and lasts for years at a time. The rest of the big blocks are too heavy, including the olds. A 440 dodge did win a main at our track this year though.
