Okay, perfect! That gives me a target to shoot at. I wasn't aware of the balance issue and bolt pattern change(kinda shows my age, but hey, I know to ask what I don't know!).

Anything else change while I was asleep? Like, bell housing bolt pattern, or the motor mount locations? What about the alternator and power steering mounts? Do the old ones still bolt up, or will I have to run the newer ones? No problem either way, but it's nice to know ahead of time.

Yeah, it's been a good while since I last did this sort of stuff, but ya know, the itch is getting strong again, and damn, I need to scratch it!

My last swap was a 3.8L Buick V6 into a S-10 Blazer('84? '85?), and before that it was a Kenne Bell built Stage 1 455 Buick into an '81 Olds Cutlass! My Grand National is mostly stock, with only headers, exhaust, and some turbo and waste gate mods.
