[Tommy T]

I've got an old (124) SPF. OK brakes with the original 351 crate. Repowered with a K Craft sb 427 and had NO braking to speak of while stuck in heavy traffic without REALLY standing on the pedal, in spite of a vacuum reservoir. Fine on the track though, ended up putting in a vacuum pump for use on the street, but not necessary when carring some RPM.
