Not counting last year ,,,,, I've ran a small block for Quite a while .

I ran 5.00 gears , 1.92 1st gear in the trans , left on the converter every pass @ 5800 RPM and went through
at 7600/7700 ,,,, in super gas Trim the car weighed 2240 and would run 9.900 @ 148/151 depending on air .

It was a 421 with Dart 23 degree heads .

I ran good parts rebuilt engine ( rings, bearings , head gaskets etc... ) every 200 runs !
