Ok I have been fighting an issue with what feels like the car is running out of fuel at wot, sounded sick running down track and popped once out of the exhaust
Verified 6 psi all the way down track
jetted up 2 sizes from 84 Sq to 86 Sq (car ran best et @84)
timing at 34*
had the heads re done springs checked good
all filters clear, psi on pump verified with visual into a tank
I am down 3 MPH in the 8th and 2 in the quarter
thinking it has to be in the distr. or box or coil
running msd distr, firecore wires, msd coil and a msd 6Al box grounded to the batt. alter is showing 14 volts
best today was a 10.447 @128.98, 1/4 6.642 @ 103.25 1/8th
best ET is in sig
Help me find the gremlin
