Default Re: new super street engine

probably need to drop the gear from a 488 to a 56 if i went the quarter stroke route. the heads i have now are around 325 cc older brodix castings that flow 370 and 310. they are in excellent shape but im sure i would be leaving a bunch of power on the table if i used them but consistency is the game so i bet with the right cam using all the old stuff would work fine. prob make 950 and a bunch of torque. i know that speed doesnt nec win races but being a little closer to the 150 plus guys would help me judge closing distance a little better

I'll take big bore/short stroke over the other way around everyday. My 522 4,560 bore/4.00 stroke makes 947HP with a 4150 carb atop it's small plenum manifold in my 3150 lb. Firebird. The plan is to run S/ST next season and I expect 150MPH on the stop.
