My combo is a 401ci. sbf w/ Turbonetics 106. I run 2 year old (stage 3) TFS High Ports. The motor is 8:5.1 comp.
What kind of timing & boost can I run with these cylinder heads? I hear they crack @ 30# Boost!!!!
My tuner has the timing set @ 20 degrees & the truck isn't making enough power!!!
I ran 7.90 @ 174.82 with 1 5/8" headers on 27# Boost....
I put a set of 1 7/8" headers on the truck & ran 8.25 @ 164.43
Any Idea's?? I was expecting to run 7.60 @ 180+
