Hello everybody!
Im currently thinking about upgrading the heads on my low comp 383 in my 71 newport. It has a Stock short block including Stock cam. Ported Dp4b intake, 650 avs2, 1 7/8 tti Headers with 3" dual exhaust and Stock 346 heads. 3.55 gear and 2000 Stall speed. Weighs in at 4600.
My prefered choice would be the cncd stealth heads because if their oe looks and good Flow.
But i think the big Ports would give Up quite some low rpm torque. I know alot of the dyno Reports on the...
Small engine big head driveability
