As far as the heads, the B heads are holding you back a bit as well, contrary to what Mogs is saying. Stage one is very mild port. What is your cam profile? There could be many reasons involved.
Again, other than what a dyno is saying, how does the car feel to you when driving???? |
yea, leaning out is what i would have expected as well. but every time they made it more rich, it got more power. it didnt want to be lean at all. (much to the shock of everyone in the shop).
the CR as advertised by SHM should be between 10.25 and 10.5:1. however, oddly, the Manley website lists the CR for my pistons at 10.96:1. is there a way to determine the compression of an engine after its built?
the intake and exhaust lift is 0.452.
duration @ .050 intake and exhaust is 209.
thanks everyone.
