    put a GM #140 in the 350 ............you'll really like how it sounds and it'll pull really hard in the midrange and this cam was designed for multiple carb applications especially for the DZ302

    257/269 @ .050 493/512 lift 112 LSA 4200-7200rpm

    was the 70 z cam refered to as the .030- .030 cam or was that the 375 fuelly,that cam went 100,000+ miles in a 64chevelle ss 4 speed 283(301)cu.in. back in my day, was a lot of fun but had no low end torke, would be side ways with the 308posi tell at 6000 rpm.,,small yellow line 14" tires,car was yellow so tires matched the car
