318 swap

I believe the /6 tranny and the V8 tranny bolt up differently. As for the engine swap itself, I just did one myself (318 into a previous /6 car). You will need to swap in a V8 K-member, or get a motor mount adapter kit. (http://www.engine-swaps.com/) I bought the kit with the intention of using them, but ended up just swapping in a whole V8 k-member. If you go the motor mount route, I still have the ones I bought unused. $160 and they're yours, I'll cover the shipping. I was told you also need to put in beefier torsion bars for the V8, which I did as well.
