Speedway does not expressly state this is a CPP500, but alludes to it. Either way, looks like a nice box and I purchased with a Holiday Discount so I'm satisfied.

Will this conversion box work with a small block with fenderwell headers? I see that the box is longer which will require that the steering shaft and mast be cut but will the box clear the 5 &7 tubes of a fenderwell header?
