I've done a lot a reseach on this, and a 455 is good if you can get HD srpings for the car in question. The 455 adds about 200 lbs to the front end over a SBO.

The 350 can be bulit-up the same as a 455. The 350 will rev a bit higher and quicker than the 455, but the 455 has more torque that a 350. However, the build-up of both motors is about the same. Plus remember this, the best thing about a SBO is the BB heads can put onto a SB engine.

Personally I was a bit bummed to find out that the 350 is a better build for me. I wanted the bragging rights of saying I have a 455 (or a 7.5 liter) motor or even the 403 (6.6 liter) motor, but with putting a 455 in my project, I need about 50 or so more HP to get the same numbers in the 1/4 mile
