Okay guys, i have the chassis complete, i have two cruiser cars. one is a Delta 88, the other is a buick. The Olds has a 350 with a power glide transmission, the other is a 455 buick motor and transmission. Up here, there has been mixed emotions about olds motors running real hot..granted the 455 flat out is a big motor, I want to save that car but don't want to have a lot of engine trouble with the Oldsmobile....What is everybody's luck with various motors. A lot of you probable run either chevy or olds..but we can run chevy in this class, might bump up next year and drop that 455 in a regal or something.

I think the Olds would be better with less nose weight.

I run a olds engine and yes they do run a bit warmer than the chevys
I was coming in around 220 / 230 was a bit warm so I flushed the rad then rinsed it out till the water came out clear changed my fan from a 4 blade to a 6 blade- non flex -non clutch came in last week around 195/200 satisfied me also there is some stuff on the shelf called water wetter or something close to that supposed to drop it another 10/20 which if it really works thats a cheap helper for around 12 bux
the olds engine is gonna give ya more torque w less rpm but the 455 is gonna be a bear in the corners esp coming out cause your gonna want to mash it suggest mash 1/2-3/4 count 1.2 then mash it to the carb

Water wetter doesn't work. Don't waste your money.

Last year we had an olds 350 that we put together. Heated up, leaked oil all over, too much oil pressure somehow(80 - 90 lbs.). A real pos. BUT!! it did have a lot of torque. About every other time we ran that car we won the race. Smashed it up one night and sold it to some other guys. They ran it once and it blew up. I would go with the olds motor. even as much trouble as we had the buick is notorious for oiling problems beyond the olds' troubles.

The buick is not as heavy as you think,it's the lightest big block GM and only 75lbs heavier than a small block chevy.As for power it should be plenty for you,in a cruiser class here they had one in a caprice and could pass 2-3 small blocks on every straight...but the buick has a terrible oiling system,i've seen them loose oil pressure,cavitate and completely unprime the pump.BTW I've got some 430 big port heads for the 455 that will really wake it up.

How much you asking for the heads...and what could I do to help the oil problem or prevent it all together?

Thanks Jester

I know thats the thing with this situation. The guy that owned it before me absolutely LOVED it, he had nothing but good things from it, won features, didn't blow, but his buddy ran an olds, took care of it and it ran hot and eventually blew up. Granted both of these cars will be set up and built to race, probably have to try them both out to see, but the way it is looking I really wish the 455 wasn't so heavy but the speed and power is there right? How well is it coming out of the corners?
