looks good, but I was expecting more torque from that car than what came out of it... especially with the long throw on the crank...  what was your average torque from 2800-6500? The lower (than expected) torque numbers are a product of a couple of things ; (1) the static compression is conservative at 9.6:1 (2) the factory manifolds don't scavenge as well as a set of headers would. Doug, nice results.....i would be happy with the outcome. This is a nice street build and should be a blast to drive !  Ron |

Hey Ron,
Yea, I'm tickled pink! I knew the power would be lower then expected because of cr, but I am pleased non the less. I think I had more torque but it peaked at a lower RPM then what the printout started at. Still...540 HP out of an engine that is 477 CID is pretty good don't ya think? I still have some jetting to do, the carbs are 90 percent there. Very broad power range...I have over 400 Ft lbs from 3000 RPM to over 6800! It looks like Torque peaks around 4K per earlier runs. This thing is going to run like a raped ape!
Bullit,
All the runs were done with the factory manifolds. I could squeeze another 60-70 HP at least with a good single plane manifold and headers. I built this for the street and to have some fun with, it is a factory Hemi car and I don't want to twist it into a pretzel after all! Any more power and I would have to modify the suspension and tie frame rails in order to use it. This is definitely the right amount of power for what it is.

Yes, that is an excellent power number (being handicapped) with the factory dual plane intake and factory exhaust manifolds. Fwiw, my 446 made 535hp@6000/ 540tq@4400.....but that was with headers and a Street Dominator single plane/ 830dp carb. These motors are pretty evenly matched in terms of power....allthough spark plug changes on yours will be a whole bunch easier !  Can't wait to see (and hear) it in Carlisle ! Ron Ps. If ya get a chance post the dyno sheet....i'm curious about how much cfm it was pulling at wot  |
