I didn't mean to imply dyno numbers aren't good for comparing different motors on same dunk, but same motor on different dyno can yield way different results that mean nothing except for tuning and checking for leaks
Totally agree. I could tell you some really good stories about some of my nearby competitors and how they sell HP. Let's just say that I have lost plenty of business by not jacking with numbers when asked to. I have also lost out on repeat business when the engine the customer built did not produce the output they "THOUGHT" it should.
I also have a few really loyal customers that understand how a dyno should be used and love not being deceived. J.Rob
Do you have your own dyno.... from this it sounds
like you do

what kind of rpms do you think this engine is going to turn? or what are you feeling is safe with that hydraulic roller?
This engine HAS to turn 6700 rpm or it won't qualify in Ohio.
I have had plenty of experience with hydraulic rollers and zero issues with that kind of rpm level. The Scorpion lifters I am using this year are incredibly nice looking with a pushrod seat that is half an inch .5" higher than their solid rollers. The pushrod length on this particular combo is 7.2"--fairly short. With a set of PAC 1255's the rpm of 6700 should not be a problem. Whether or not it makes any meaningful power up there may be.J.Rob
What's the highest rpms you have turned with the hydraulic rollers? do you always use the Scorpion lifters?
The highest I have turned repetitively is 7000 rpm with hydraulic rollers (Hughes lifters/W2 combo)
I always use Scorpion lifters now that I am a dealer. I believe they are made by Johnson Hylift. The laser etching on the lifter body of their solids would indicate that. Scorpion products are real high quality and priced right IMO. I will put up a photo of the lifter.

A picture of the lifter would be cool...thanks

I think here's the weakest link. Put my guess in the 560HP/530TQ range.
Schoenfeld 1 5/8" 1 3/4" step headers with a 3.5 to 3" hillbilly merge
Consider it noted. I think your guess is quite sound according to my experience with the 4" arm combo. J.Rob
I don't think the header size is that big of a deal. Everybody thinks they need a 1 7/8" header with a striker but I usually see a huge hole in the torque curve with them. The extra couple of horsepower up top with bigger headers may not be worth the loss down low.....

555Hp and 530Tq.
I sincerely hope you're wrong! J.Rob
After looking over your specs, I don't think Brian's too far off. But I'm basing my opinion on some big-block testing I've done, rather than any first-hand small-block experience. 
So, how soon will you have the engine on the dyno?
