I would go with the cubic inches. All the blocks are the same. Just bore and stroke differences. The 352 will have the same stroke (3.50") as your 360, just a 4.00 bore. The 390 will have the same bore (4.05) as your 360, but a 3.78" stroke. I would measure the stroke of any engine being claimed as a 390. Why not rebuild your 360 into a 390?

well i kinda screwed up the head on the 360.in the prosses of taking the exaust manifolds off i broke one of the top tabs that hold the manifolds on.it broke off pretty far back.so between new everything for the 360 i was wondering if just starting out with a 390 would be smarter $ wise.i just need it back on the road quik so i might just weld the tab back on for now and build a 390.

Dave, a 390 has 40 more cubes, and bigger is always better, right?
A good bolt in 352 for a couple hundred bucks will handle your truck just fine.
Going for a rebuild, than go for the 390. IMHO
