My small block is 394ci. which is larger than yours, that would probably make a difference. But roller cam is 255/266 @ .050, 10.9 to 1 comp. Mine has pretty good bottom end 1.33 60ft. and I have ran 109 mph in the 1/8. I Believe if I had more duration at .050 I would not have a lot of cranking cylinder pressure. But I can run pump gas. It is 190-200 now.

1.33 60 ft,6.21 at 110.59 in the 1/8, pump gas small block,2950lbs,drag radials,mufflers and driven to track ...
