Ok, I'm as mopar as anyone, but please explain the math on a 600'' s. b.c, and how it all " fits"inside the crankcase. There is a write up of one on engine labs site, longer block, larger bore spacing and 4.9" stroke IIRC.

A lot of people underestimate the power that Victor heads can make. Any head that can easily flow 370-390cfm can make horsepower.

Great power out of that build, especially when considering how many struggle with making 750+ with those heads. If you don't mind a couple of questions:
What compression? What are the rough cam specs? What were the flow #'s and what did you have to do to get those?
Thanks! Compression is 12.5 , camshaft is 275@.050 intake 279@.050 exhaust. 113 LSA intake is 109.5 centerline. A lot of thought went into the camshaft and particularly the intake closing point. The Victor head is way better than most give it credit for. Any of the 350cc cnc programs will get you right at 385cfm @.800 with the 2.2 valve. For my heads, I am 355cc, 2.2 valve and flow a TON. I stayed with the 2.2 valve on this set because the 2.25 on my first set didnt yield much. I thought it made the port a little too slow. I may post my flow sheets some time. I would like to get the car on the track and see what kind of power its making. Dynos and the track are 2 different animals.Valve train is atrocious on these heads. This is my second time using them. I recommend milling the rocker stands off and use longer valves. At the end of the day, thats the only way to get them right. Anything else is too compromised..

Over the last several months I built a new 540 for my father-in-law's Duster. I was going to refrain from posting this until we got the car down the track, but I am bored. In my experience, very few will realize the corrected power that even a 'conservative' dyno will show. As long as I have been in the testing community just about ANY data is relative if you want to learn something. It's a point of reference that the skilled can use to anticipate potential. Regardless, you being apprehensive to post any information is respectable. But then the debating is entertaining, lol. After reading more of your posts, I have less doubt that's what it made. Does anyone know of any near 900HP (as verified in-car) Victor headed motors?

Does anyone know of any near 900HP (as verified in-car) Victor headed motors? Also much consideration must be given to how well the car and driveline are scienced out. My dart as an example, many things are less than optimum. I leave soft for consistency. Tight converter. I could probably use a different set of trans ratios. Weather. Headers are close, but may not be the ultimate. Still, the car had some amazing performance show up on parts of my runs. So all in all, despite some guys saying it ain't got the oats the dyno sheet says, I believe it does, it just isn't applied perfectly. After all, nothing is ever perfect.

I have no reason to doubt BES' numbers, but find it odd that their dyno printout doesn't include any of the basics like AFR, Fuel Flow, Air Flow, etc., included

Thank you, that agrees with what others on here have experienced. That much power with only 12.5 compression is even more impressive. I am assuming your cam lift is in the .800" range and you upgraded to individual rocker arms as mentioned. Would you have any more information on that modification that you would care to share?

Did you try revving it higher to make sure the motor had reach peak RPM and not started a dip that would go away in another hundred RPM? What type of cam and lifters and valve spring pressures? I'm running a Jones solid roller with crower lifter. Springs are 255 on the seat and 660#'s over the nose. I told Rich we were shifting at 6800 before we started, regardless of power curve. It may be flawed thinking on my part, but I believe an oem block has a better chance of living if you don't rev the piss out of it. I sized everything when designing the motor to peak at 65-6600. Heads, cam, intake, headers, ect i am solidly behind the path you chose here. Knowing my rpm graph shows actual rpm of the 1/2 shift to be higher than the programmed rpm in rhe electronics activated air shifter, if it were mine i would start by shifting by eye at 6400, 6500 if an air or electric shifter is in use. Add a hundred rpm for the 2/3 shift. From my limited experiance those heads are making about the limit of thier hp capability, and then some. What do you think is the cause of the discrepancy of the programmed shift rpm and actual shift rpm? We don't have any data logging yet. We may in the future.
