On the cam you mentioned that it was previously at 4*..that
would be 4* degrees advanced. if its a three keyed gear on the crank you have the option of straight up, advanced or retarded. advancing a cam brings the powerband down a couple
hundred rpm. retarding it brings the band up. being a street
car i would put it in at 4*A advance..the keyway on the crank should be straight up.thats TDC (top dead center).
put the keyway marked 4A there.
the camshaft gear has a dot on it. That will go straight down at the bottom (180 degrees). you want to align those 2 marks. then remove the cam gear just enought to install the
chain and work it back on..make sure your dowel pin is long enough.. should be at least 3/4 of the way through the gear to flush...
valve train geometry is very important..what kind of rockers do you have? stock stamped steel, bolt down roller
rockers, or adjustable roller rockers? if you have anymore questions you can email me direct at eric.r.larson@lmco.com
