68 Camaro 3300lbs SBC. 7500rpm in the traps.
6AL box, MSD distr.

Mid-season, I had a miss that progressively got worse. Started at the top end, and eventually all the time. Popped like it was on the limiter, so pulled the high side chip. It didnt fix it.
Started watching the fuel pressure, and it was all over from run to run.
Turned out to be a weak fuel pump.
Swapped it out at the track and has run perfect since.
