Just A thought......

Cardoc · 09-29-2006, 01:56 PM

I was sitting, spacing out for a while today..and I was thinking...what if I were to get a 455 or 425 toronado engine and put it into my '69 Cutlass(if its even possible) what sort of parts would I have to get to make it compatible?..and what transmission would have to be used...4 speed std. preffered. I thought since Im a body guy, and not an engine guy...someone here might have some food for my thought.
Thanks - Darren

Hello Darren, any 425 or 455 will bolt in with the right engine mounts. Toro mounts are different, you'd have to get new mounts or use the same (8 cyl) mounts that are in your '69 now. Also you'd need to change the oil filter mount from the toro because the angle is different. The one from any other modern Olds 8 cyl will bolt on. If you want to use a 4 spd you'll need to have the crank drilled out for the pilot bearing. Olds only did this w/ engines meant for a standard from the factory. A turbo 400 was the stock trans used on a big block, although a turbo 350 can be built to use. A 400 will use a larger yoke & is longer than a 350. Good luck, Jerry.

You will also need to replace the exhaust manifolds with headers or manifolds from rear wheel drive cars. I would also replace the intake manifold, not that the Toronado intake wouldnt fit, but it sits alot lower to clear under the hood on Toronado's and doesnt have the performance of a higher rise intake.
