I went to a local speed shop here yesterday and strapped the vert down on a chassis dyno. I did three pulls and they were all nearly identical. The best one showed a max RWHP of 380 @ 5,250 pm and a max RW torque of 460 ftlbs @ 3,250 rpm. This is nearly 100 RWHP above my previous motor that was in the car when I bought it. Overall I was pleased with the numbers considering it is a mild to medium build with manifolds for the street. The operator estimated my crank HP at around 450. He said for comparison he has had several new Challenger SRT8's (6.1L) on his machine and they come in at about 340rwhp. Thanks to those here that helped with their expertise and info for my build!

very nice...

Thats good RWHP #'s. Tell us your build againg as I dont remember it all. Ron

Nice
Are the numbers uncorrected or corrected RWHP?
What type of Chassis Dyno?
I know DynoJet lets anyone download their winPEP 7 software, so if you have the dyno operator E-mail you the run files you can display the information in several formats and with different correction factor types with the software.

Thanks guys. The dyno was a Mustang and the tech told me it is conservative by about 15%. So those numbers are corrected up, the actual reading was 340 rwhp. My build is a 440 .030 over, diamond flat tops at zero deck on 440 Source tapered I-beam rods, 440 Source heads with what I would call a 'stage one' port job, cam is a Comp retro hyd roller #23-710-9 which has 224int/230ex @ .050 duration with .538int/.534ex lift and 110' lobe seperation. The intake is stock six pack with Promax prepped carbs, HP ex manifolds and 2.5 ex all the way back with muffs and resonators. Static comp ratio is 10.0 to 1 with .043 quench distance and about 190 psi cyl pressure. I'm running a TKO 600 5 spd behind it with a Dana 3.54. It pulls hard from about 1,500 rpm all the way to 6,000 where it hits the rev limiter. I know I could do better with some headers but I like the stock look and show the car often. The tech told me he thought it was a good motor considering I'm running manifolds.
