Engine and transmission swap
#2
A TH350 trans is also a bolt-in.

Joe, I interperetted his question to be asking about the TH350. My counter question to him would be, has the transmission in your car failed in some way? If not, why are you looking to replace it?

Swap.
Hey. This is a thread with my name on it. (sort of) I have done the swap you are looking at doing, even the same car. As said earlier, an Olds 350 or 403 is a bolt-in. A th350 tranny is as well. My opinion, a 350/350 combo would be your best bet. 403's have more limits on what you can do to the block. Also, bigger engine means bigger tranny, here's why. Bought car in May 98. Did engine swap in July 98. Put in a fresh 70 350 W31, with #6 heads, to the 200 tranny. All of a sudden Jan, 99. Had to install a th400 tranny. (It's the one I had, and I had to modify trans bracket for that) Now, untill last summer, I was still running the stock 2:29 rear axle. No issues. I am changing it this year in favor of a 3:73 ratio, as I am in the middle of a frame-off resto, and it won't be a daily driver any more. Check out my pics in the gallery. I'm sure we'll be adding to this thread. PM me if you want.
Jim.
