Hi everyone, been really ill and haven't been involved for a while but good now apart from results of engine build.
It's a .060 block 10.5 compression with the oiling mods that are recommended, Edelbrock heads and perfomer rpm intake cleaned up faced and portmatched, Harland Sharp rollers ,FPA longtube headers, Comp hydraulic roller 232 and 237 @50 , 524 and 535 lift, 106
degree centre line and 110 separation, 780 vac sec holley. Have been on a chassis dyno and can't produce any horse power over 4500 rpm. Torque starts at 1800 and peaks at 3400 then holds through to 4200 before starting to slide off. HP is a pretty flat curve from 3300 and peaks at 300 rwhp at 4250 then starts to die off and it's all over by 4900. The ignition is Msd distributor 6al box ,18 initial - 37 total all in by 2800. Have played with curve and initial combinations and this works best, have also double checked degreeing of cam
Exhaust is twin 2.5'' from headers to x pipe high flow mufflers over diff to rear. I really expected this combo to produce to at least high 5's or 6000. Comp states this cam should be good till then I'm a little frustrated .Where have I gone wrong.
