Poor quality video, but you get the idea.
First pass with the Dart Iron Eagle heads and a new 750DP Holley. 12.52 @ 110 mph. I later bumped the timing up to 36 degrees of total advance and trapped 113 mph. I hope there is a little more left in it.
The other car was a '96 Z28, he ran mid 13's.

Re: Video: First pass with the Dart heads
I don't think a looser converter will help on a 26" slick with 4.56 gears and that super deep 3.06 first gear in that trans. I feel that is too much torque multiplication right at the line and the converter is the only thing helping those tires to not blow off the line.

Re: Video: First pass with the Dart heads
I am actually running a 28" tire. I previously tried a 26", but it would practically destroy the tires.

Either way that car will be a handful, that would be like running a 5.13 gear on a TH350

Re: Video: First pass with the Dart heads
I have no idea how much HP it has. I suppose I could get an estimate based on the car's weight and trap speed, but I haven't weighed the car. The body is stock with the exception of a fiberglass hood and removed AC/heater box. Full interior.

Re: Video: First pass with the Dart heads
needs more cam, sounds like it needs more compression. you'll get far better results i think. those heads are huge.

Re: Video: First pass with the Dart heads
miss matched combo for sure, but it's moving the car along and band aiding a gear reduction problem for now.
you put a smaller gear and your stall speed will raise up a bit since you'll be riding the convertor harder without all the gear reduction.
