I was originally going to run 10.90, but w/ the #'s it put out I'll have to slow it way down. the car wieghs less than 2800 w/ me and a the big block in it. After I get comfortable w/ the car I may try super gas ??? - The car is back halfed and has 32x14x15's and a 727 w/ brake and 4500 stall. Thx for the comments I read a lot of your posts.

HP seems kind of low, what rpm was it run up to?
6300 rpm @ 37 degrees timing #88 jets and it was 97 degrees ambient we were going to do a forth pull w/89's in it, but were not sure if we could duplicate correct air flow to justify it. Fuel per horsepower usage was dead on @ .397-.440 per # (you dyno guys will what I mean). ---- As far as low #'s!!!!!!! THIS IS NOT AN EXOTIC RACE ENGINE AT ALL. It is off the shelf parts - shaft rockers edlebrock heads etc. most (several engine builders) I spoke w/ assumed 650-675 including the shop the did the build. EVERYONE was very happy w/ the hp and the tq - they have done several builds similar and this was the highest producer yet by almost 35hp and 40tq. Shop owner said the heads came out REALLY NICE and that was the difference (335 @ .700). If I had B-1's or Indys I could see your point, but you could call Jegs or Herbert and probably have everthing in this engine shipped to your house w/ in a week.

Sorry, I wasnt trying to dis your build or make waves, it just seems that the hp peaks out at a relatively low rpm. Im sure that the engine runs great, and will really move your car.

Great power I can imagine the torque curve is very flat and useable from all RPM. is it a race only car? The reason I ask is if you've got so much torque you probably could put in a tighter more streetable converter and take better advantage of all that high port velocity grunt right off the line at 3200 instead of the vert side stepping most of it all until 4500. What gear is in the car?
Awesome power....hitting 700HP with a stock-ish 906 size port window is very impressive.
I thought the numbers were a little low at first too. The Victor headed motors I have seen on here and in magazines usually are in the 750+ range..but they were max wedge ported and had bigger cams, so that would explain the difference. I agree thats very good steam for that combo.

Its a strip car only. It has a narrowed dana 60 w/ 4.88's in it. I thought it might blow through the converter a little since peak tq was @ 4800. or that it might just stall a little higher. Should I be expecting something else??
