Well, I probably am leaving out some details, but a friend of mine built a similar engine as mine....And asked if would come down and watch it being dyno'd....Of course I said yes, and brought my Thumperized 1250 Dominator to try if we had time.
Build specs:
572 Hemi
Eddy heads
Solid Mechanical 283 dur @50 .680 lift
9.5:1
World Block
Intake....Depends! But probably a Six Pack.....Yeah, Sixpack Hemi!
-We tried a heavily modified six pack on a Modman intake first...This is Rob's engine, and for anyone who does not know him in the Mopar circles, he IS Mr. Six Pack.....He has been racing these six packs on Wedges for so long, I don't think he could help himself and built one for the Hemi. I was very glad he went with the Modman intake on this build as well.
-First of many pulls was with the sixpack...Lots of tuning went into it on a basic run in stand with an AFR gauge before the dyno, but without a load, its tough....
Best pull with it was 741hp & 666ft/lbs....lots of tuning to get it there. Still needs work as the transition was blubbery with the vacuum carbs coming in...I prefer to run three mechanicals over anything vacuum, but I am sure he will figure it out.

Fired right up to a perfect idle, and then mad 779hp & 717ft/lbs of torque....No adjustments other than floats....
