Nova question..

The clamshells on the subframe are the same as the V8, so you just have to get the correct length/width outer shells on the V8 block. Worst case scenario, you have to move the mounts on the subframe some (multiple holes drilled already), but it's no big deal.



I have a 400cid SB lying around that my friend is going to borrow from me this summer, so we'll have the same swap coming up this spring

There were some minor changes to the 2nd gens over the years, and I forget the exact break year, but I thought I’d mention it. The sub frame changed, probably in 75, for clearance room for the cat. The lower control arm bushing size changed, maybe in 73, but I am fuzzy on the details. I am unaware of any change to upper control arms.

Maybe search http://www.nastyz28.com/forum/index.php for more info.

I did the l-6 to v8 swap on my car. The small block fit perfect with no need of changing the mounts.

I know this is an old thread, but I'll revive it. I am working on a '77 Pontiac Ventura. What started as a simple engine swap as grown out of control. I am looking to see if the tall balljoint will help when I reassemble the front subframe. Here are some pictures for everyones enjoyment...






and the reasons for all of this fun...
toasted subframe bushings ( here are the bolts)


and the core support was completely rusted. the body bushings were long gone.
