I am assembling the parts to rebuild a 1957 312 y-block. I have the G heads, B intake manifold, 1.54 rocker arms, 1957 distributor, Pertronix ign., Holley 4160 600 cfm carb and the larger later model exhaust manifolds. Where I need a little help is the cam and lifters. I have narrowed it down to the Isky 301333 or the 301444 cam. Which of these would be best for a street use engine that would only need enough power to pass when needed or to get in or out of traffic quickly when the need arises. Or maybe an occasional adrenaline rush! Also, are Isky solid lifters a necessity with this cam or will other brands such as Comp Cams suffice? If any of you with knowledge and experience of these cams and lifters could help me out with this, I would sure appreciate it! Another question I should have asked: Would a stock Melling cam deliver the same or acceptable results? The reason I ask is that I already have one of those. What would you do in my place? Thanks.
