Drag strip launch problem

1\2" fuel line and higher rpm. I used to launch my 71 Duster at 5300-5500 rpm; it was 440, 4-speed, and 4.10 gear. Everyone thought I was crazy to launch that high of rpm, but their cars were much lighter than mine and that's the rpm she liked. Anything less and she would fall on her nose and stumble off the line. Put some throttle to her; she'll like it!
