I thought I read in the rules one time you could not use a block that would take a bigger bore than stock?

Also would it be limited to a single exhaust?

I had a 360 in a 66 dart 4dr with 302 heads 273 manifolds and it ran a best of 9.43 in the 1/8th with a one leg 7.25 2.94 rear.

Could I run an 8.75 or 8.25, I think they only came with 7.25s in 65?

I am not causing global warming, I am just trying to hold off a impending Ice Age!
