Bandit,
On paper it may seem the big torque BB will beat the small blocks, but with a 2500 lb cobra anything over 650 hp is a waste of power. You can only fit so big a tire in a Cobra and if you can't put the power to the track you can't use it. Did you ever notice the tires that the BB modifieds run ? They are sometimes 18" wide.That's the kind of tire you need with an all out big block.In an all out drag car you can run the bigger slicks if you open up the wheel wells, than maybe you can put all that BB power to the ground.I run 11 in rr slicks in my cobra and can spin the tires coming out of most corners with a little 351 Crate motor. You just don't need BB torque to be fast on the road course.
Scott Coyle knows what he is talking about and most of the experts agree, small blocks for road racing.
Even the Shelby 4000 spec racer is built with a 351 windsor.
Build as big a motor as you want but don't be surprised when you get blown away by a small block.
