My previous car was a street/strip 65 GTO with a 389 tripower and a 4 speed.

After much fiddling I got it to run 13.30's pretty regularly. Then one Sunday , it stalled when I did the burnout. It had never done that before. It restarted and everything was fine, BUT, it got me wondering if I was running out of fuel with prolonged high RPM.I added a Carter electric pump, and the next weekend the car ran a 12.97 and speed jumped from an average of 105+ to over 107 MPH!!

Prior to stalling that one time it never displayed any symptoms of fuel starvation. It always pulled strongly all the way through the quarter.

The engine probably made an honest 340 HP.

Food for thought.
