when you look at the dyno graph you'll see that the horsepower hangs from 5300 to 6600. I've seen other dyno graphs that pull to 6100 and then start to come down. one the first pulls the throttle body was only opening three quarters of the way. once we fixed that it only picked up 10ftlbs of torque, horse power remand identical and again hung from 5300 to 6600.

The motor has
ported L76
L92 west coast cylinder heads
HK engines 418ci
Kooks long tube headers
90mm nick williams


Any help will be appreciated
thanks,

jose de la paz

going to order new one and see what it will do and if not then it will have to be a carb intake . this is crazy.

intake manifold limited, get a vic jr on there IMO

i think a carb style will kill the bottom end. the only other one out there is the fast. but its a lot of money to find out its not the problem. damn those gremlins.

what kind of lifters?

jose de la paz

its making power but it should pull to 6100. not so worried about the numbers just want it to run right. looks like its going to cost a lot to find out whats wrong.

jose de la paz

lifters are LS7

Valvetrain issues possibly?

What cam, springs, pushrods, and rockers are you running?

jose de la paz

CR 11.3 to 1. spoke with richard at west coast cyl. seems like air restriction. he thinks its the intake. well soon see.

jose de la paz

WKMCD was your intake ported. mine is, dont know if it could have been damage during the port work.

i was thinking the same thing. having valve float problems? intake definatly, could be a number of things

jose de la paz

was talking to erik and richard. they dont think it is a valve train issue because its to stable.
