The new engine is built w/replica #140 cam from Howards Cams, they say it is new technology w/smoother opening & closing ramps than the old GM cam, lash is .022/.022, It has 1 hour of break in time at fast idle from 1200 to 1700 ,, fine tuning the carb. & distributor the 302 is getting very crisp and idles down to 1000 rpm nicely, i need to adjust a couple things but so far it is running great.
I will not dyno the engine, just curious what approximate HP would be.
