Bigblock V6: Thanks for the quick reply. Your information is exactly what I was looking for. I had hoped the 432 was internally balanced, but I guess not. Onwards and upwards.

I was originally looking for a 478 for my 1-ton pickup, but I couldn't readily find one with the resources I have. I stumbled across the 432 at Anderson Brothers Truck Equipment (used trucks, parts, etc. in Eugene, OR.). This was the biggest GMC V6 they had. They also have three 351's. I scoured through all the parts to find what I needed to complete the 432. I did find a pair of good ToroFlow exhaust manifolds and a pair of 432 manifolds, but one of them is cracked, so I settled with a slightly smaller 351 set of exhaust manifolds.

I did find a 401 with a 5sp. for $1,000 but passed it up. This guy is selling a bunch of GMC body parts/trucks and motors through Craigslist in the Salem, OR. area. He also has a 351 or two.

Thanks-a-bunch, Mx.
