M1ke said:there's a guy on another forum that has his npi heads p&p'd and assembled by steen racing. ive heard nothing but good things about them. with those heads and cams he dyno'd 309.43/316.62 rwhp 4.6L 2V NA
depending on the turnaround of steen i wouldnt mind taking my npi heads of and getting them worked on by steen and drive our beater truck around till i could get em back and installed.
check out their site http://www.steenracing.com and go to products. if you talk to steve i think it is, he could set you up with the right package and stuff
Can you tell me what forum and what the username was on this guy? I really want to look at what he had to put down those numbers to see if it close to what I am building for my car.
Thanks,
Lee
