so, i let my oil get a little low, lifters and valves were making noise for awhile, then one day warming up my truck to go home from work, it starting making noises, more than normal. thought it could be rod, got my stethoscope, no bottom end but A LOT of top end/: its getting worse and worse losing more and more power every day/:
Lobe center: 112
Advertised intake duration: 256
Advertised exhaust duration: 252
Intake duration at .050": 202
Exhaust duration at .050": 189
Intake lift: .358"
Exhaust lift: .317"
thats my stock cam specs, im looking to get a new one, and i might as well upgrade, so im looking to see whats the longest lift i can get with stock valve springs. im looking to keep low end torque but want a bit more around 2500-3500 rpms. i found one with a .400/.400 lift, is that to much for stock valve springs?
