Ok ... It will run fine @ 106.....and will "retard" to 107 or 108 as timing chain relaxes

Thanks for the link steve,I'm running a 273 gear and hope this will work better with timing at 106.I still would like to perform a compression check.Prior install it had 180 I'm expecting 190 -195 ,if it goes higher then 200 I'll be going back to 108.

Well this is strange, I performed a compression test and only got 160 psi,seems low.Was expecting 180 at least.Did test with engine on stand .May need to seat rings and then retest.

OK finally running again,feels a little more responsive off idle.Haven't made any full throttle stabs yet still breaking in,is a little noisy until lifters fill up.Will do a compression test soon,but curious if I will get legit readings due to the lifters compressing and closing the intake sooner
