But racers are racers, they will ALWAYS run their stuff until they break, one way or another.
(This is the "Street" section BTW).

Thanks Kenth. Seems like every post goes to drag racing/max effort somehow somewhere, that’s why I posted the build of a 9ish:1 street cruiser. Sounds like KBs might be an option I’ve never considered. My builder is well versed on Pontiacs so I’d just have to reminds him about the clearance.
Do you know how much weight difference there is between the KBs and the Speed Pros?
