it seems really weak off the line at the track

70 camaro, 355, 12.7:1 CR, dart pro-1 230cc, 2.08/1.60, 64cc chamber, victor jr intake(IIRC), cam is iirc .633/.633 solid roller(better specs later), power glide w/trans brake, ladder dana 60 rear w/ 4.88 gears, and 32 tall slick(exact size later)

here is a time slip

60- 1.6410
330- 4.6432
et@594- 6.6801
1/8 et- 7.1580
1/8 mph- 94.15
1000'et- 9.4879
1000mph- 104.94
1/4 et- 11.44
1/4 mph- 115.39


and here is a slip and video

60- 1.6470
330- 4.6291
et@594- 6.6521
1/8 et- 7.1081
1/8 mph- 98.68
1000'et- 9.2862

1/4 et- 11.1501
1/4 mph- 120.63

and this is a video of the 11.15 run





I am kind of thinking converter, it stalled near 5500 behind his big block, but i am thinking it is stalling too much lower behind the lower torque small block?

he is opposed to nitrous, but I have him thinking about a converter if needed, and he plans on new slicks

Hard to say for sure, but sounds like it's blowing right through the converter

hmm..., maybe, think we might get a better idea by throwing it on the dyno?
