Re: motor bolting to tranie

Not sure if i understand your question, but if you are putting the cutlass tranny in the truck, be careful. Not sure about that particular tranny, but most trannys in trucks, even if the same model, were built with stronger cases, etc...

Re: motor bolting to tranie

<font face="Comic Sans MS">If you're asking whether the engine from the Olds will bolt up to the transmission that's already in the truck, the answer is no... Different bolt pattern between the buick olds pontiac engines, and regular chevy/gmc engines if I recall correctly...

If you're asking whether you can bolt the engine and transmission out of the Olds into the truck, I would say no, because you'd have to find a divorced mount transfer case, and stuff like crossmembers...

Basically either way it won't work, or at least not well at all... Might be able to find a decent replacement in a parts yard out of a lower mileage rollover, or something... Worth a shot anyhow... </font>

Re: motor bolting to tranie

You CAN put the olds trans in the truck is they are both the same ie th350, but, you will have to put the 4x4 output shaft in the olds trans which requires a complete teardown of both trannys prob cost $100 - $200 min at a trans shop.
I put a caddy 472 and olds th350 in a k-20 but I swapped the shafts myself. ...... mmmmmmmm pizza and atf ..... can't beat the taste!!

I'm with Sandman here. The Olds engine and tranny have different bolt patterns than Chevy. It's the Buick-Olds-Pontiac (BOP) thing.
