OK. Just did a cam head intake and full exhaust job. How much power do you estimate? I have nothing to compare it to so no way of knowing until I get it on a dyno. I thought I might be able to roast the tires from a slight roll, but to no avail
. Maybe I was expecting too much. Does run good. Lot better pull through the entire rpm range. Its definately faster, but I can't tell if its 40 hp more or 100hp more. Here's the specs and I'm still tuning it and have a wideband too. So any tuning suggestions are welcome too.
94 k1500 ECSB 5.7 stock bottom end.
hedman lt headers
2 1/2" duals with x pipe and cherry bomb turbo style mufflers
212intake/218exhaust @.50 with 480/490 lift roller cam and matching valve springs
906 vortec heads machined for higher lift with a quench of .040-.045
victor jr 2 bbl intake
3" open element on stock tbi with 61lb injectors with ultimate tbi mods
13.5 lbs fuel pressure with a new tpi fuel pump
I was expecting to run out of fuel at high rpms, but the injector duty cycle never got over 50%. Makes me wonder if I'm not getting all the power? Or is it because the intake is a single plane and can draw from both injectors?
Thanks,
