Re: Thoughts of swapping in an Olds 455 w/400 trans in '64?

I have alot of Olds parts and engines on hand, just none for sale. My moniker "68post" is for my 1968 442 post coupe that sits in my garage.

You're gonna have a ton of fun sliding sideways. But the 455's don't take high rpm well without some changes, I'd set a rev limiter to about 5,200 rpm and ENJOY !!
Yeah, I'm going to have to be careful with the throttle on with this beast, especially with the lsd and corners. I've never had a vehicle with this much power, but man am I excited. I don't plan on dragging it or racing it, but I've heard that high revs can suck the oil pan dry and cause some catastrophic problems.

With the length of my th400 (long shaft) I'm hoping I'll be able to find a one piece driveshaft from a different vehicle that will fit without modifying, other than u-joints. I should be installing engine and trans within the next couple of weeks then I can measure the length needed.

Building the engine rather than buying makes me quite proud to put in to my '64. I can't wait!
