Title: cam and carb help
Post by: 70f400 on September 29, 2015, 12:38:00 PM

I got this cam today supposed to be the "Old Faithful" but it is a bit off.  I am hoping you can give me your expert opinion on whether the run it or send it back.  If I do run it should I adv the cam for a 108 icl? and I have 1.5 full roller rockers do I go to 1.65 to make up for the smaller lobe lift.

duration @ .006   286/296
              @ .050   236/244

events @ 114 icl

468 Pontiac,  10.7:1 compression, KRE 290 D ports,  Factory Aluminum HO intake, Ra 2-1/2" manifolds. 3600# 70 TA, 3.42, 700r4 with 10" continental.

1705 726 Qjet with 73 jets, 44 pr rods .039 idle tubes, .059 Idle down channel and .110 by pass air.  What changes do I need to make if any to the carb?

Who supplied the cam?  I'd contact them with your questions....
