sounds like fuel starvation to me. Nothing in first gear then all through the second half of the track. What kind of fuel pump?

Yep. Fuel issue. Just because you have good pressure doesn't necessarily mean the motor isn't starving for fuel at the big end. Ignition, valve springs,etc, would most likely show up in every gear.



I thought so too.......I sent the box to Tx. ( MSD 7 AL )and it checked good.
Swapped chips for r.p.m. with ones that I knew worked.
I was pulling plugs and showing them to guys I trusted , checked connections , set and re-set floats and regulators , did the volume test etc.
But when the motor was pulling hard in 2nd and 3rd , it sounded just like it was on the chip.
It was a valve spring.
1st revved out just fine , so it didn't make sense to me either , but that cured it.
