H/c low dyno numbers in m6
My 01 ws6 just recently was rebuilt with a cast iron 5.3 bored to 3.903 and has eagle rods weisco pistons with patriot ls6 heads and a ls6 intake my car only made 400rwhp I thought that was really low the cam is a comp 232/236 with .615 lift 114lsa my valvtrain is pretty noisy and I think that has something to do with it could that cause a loss of alot of hp ? The tune is right on and done by a good shop it was on a mustang dyno , any input would be appreciated

Nobody ? The only thing I used that was used is the cam and the machine shop inspected it and they measured and assembled my whole valvtrain is it possible that a used comp cam could cause a sewing machine like valvtrain ? I'll post my dyno graph soon

If you made that power on a mustang dyno with that combo then your making good power. Whats your dyno graph look like? Good power under the curve?
Also a lighter valvetrain can free up some power.

400 rwhp is pretty good. The patriot heads are not the best flowing either. I confirmed by talking to them, they do flow less than PRC and they use a 4.00 bore plate
BTW, the butt dyno is the most important dyno out there. The #s mean nothing, its the smile on your face.

Yes the car feels faster than only 400hp just can't wait to get my bottle filled and see how a 150 shot feels , I also am running the colder plugs for the nitrous ik that can loose a couple hp

yes the sewing machine noise is pretty common when you do heads and cam, did you check for proper pushrod length? to short a pushrod will cause a loud sewing machine noise and beat the valvetrain to death
