[BTR69]

Curious on crankcase evac systems. About to put the money into one and looking for what works best for most of y'all. Looking at preferred brand/model and also belt driven vs electric. Seems to me less pulleys running off the crank would be a better option, but do the electrics pull enough vacuum?
Will be going on 355CiD SBC. Roughly 450 hp, powerglide & 3400lb car.
Primarily raced, but will ne street driven a time or two monthly.
