It is a 2nd series
I should state the goals of the truck. That may help with where this thread belongs.
I am not building a drag truck, I am building a DD truck that I can use as a work horse truck pulling trailers with the race cars on the trailer. I figured that would be a good purpose for it because it is a 3/4 ton truck.
I also have a 350 Chevy with a th350 trans that I could put into it, I just figured the Buick 455 had more torque for the pulling. I plan for the most part to leave the 455 Buick Stock as the heads are prepped for Unleaded gas and from what test have shown not much need to be done to them. I also plan on leaving the cast iron exhaust manifold because they sit close to the block and compact unlike tubular headers. The block is also shown to weigh as much as a small block chevy and not nearly as big as a 454 chevy big block
