383 info for you
That vega should fly, I do not like the short wheel base ,but it will be a fun ride.
I had a 435 HP 383 (SBC) solid roller, very good steel GM heads,750 DP holley, approx 10.2 to 1 in a 3500 lb 70 chevelle 4;10 gear (12 bolt) T 350 with good inners, never hurt it,never hicked up, always started, street drove it. Very fine combo that went 12:20 off the trailer. First time I had raced since 1980. I got the car to run high 11's consistantly, two things I would have changed.
1. I needed a higher stall,(I had a tight 2500) needed a 3500+
2. As long as you do not mind the maintanance and wear and tear on the valve train (and cost) the solid roller is ok....but you may think about a hydralic cam, they are better than they used to be. You give up some performance and sound and 10:50 is an agreesive ET ???your call, that is part of the fun
Just as a note that 70 Chevelle has evolved into a very fast street car , check out my racing profile, if interested
Hey good luck ,stay strait and fast and safe,
there is no better fun in the world
