555Hp and 530Tq.
I sincerely hope you're wrong! J.Rob
Lets just say that I'm sure the potential to get close to 600Hp is there...I guess it depends on the dyno to. On our dyno I would expect 555 or so. On a Superflow I'd think maybe 575...Stuska I'd expect 600!
Alot of people argue over happy dynos low dynos and lets not forget the infamous track. I would like to know. If a car is not sorted out properly does the MPH dictate what ET you would be able to run with a good car? Does the MPH stay constant (to a degree) even if the ET is lacking??

We race CARS, so it only makes sense, to me anyway, that the car needs to be as good as the engine, trans, etc... So if you don't pay alot of attention to things that help mph like front end alignment, tires, pressure, oil viscosity, brake drag, and such your not going to get all you can. It's easy to say on the net that your cars mph is xxx but what it takes to achieve that is probably not so easy.
Truth is different dyno brands will show different #'s...hell same brand dyno's can show different #'s depending on so many things. Just like flow benches. In the end, what the car runs is also dependant on many many things. I see alot of customers that want a certain mph or e.t. but may not be willing to work on the car until they get it...if they buy an engine they figure it's the engine builders responsibility to make their car meet their expectations.

I had a very similar combo 2 years ago....
Let's not forget a dyno is only a dyno, it will not tell you how fast you will be going...or how quick your car will respond....
May be a bit short on cam duration, but my realistic guess will be 475hp and 480lbs tq at 4800rpm
you have very good quench with those pistons, so a very efficient combustion chamber...
One way or another, you'll have plenty of fun !!

568 hp @ 6200 rpm and 558 ftlbs @ 4200 rpm.
I think this is real close

I think the "big" intake, and low compression will hurt torque more than most on here seem to think, but i am usually wrong...lol
Gonna say it will make " dragstrip" power equal to having 540 horsepower and 525 torque. Dyno is so subjective it can say anything. I would guess in a full weight 3300 pound A body its a 10.70-80 ish( 124 mph) motor in front of a 727.

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?

I think here's the weakest link. Put my guess in the 560HP/530TQ range.

Arrington claims 630 ponies out of a 426 inch gen 3 using a much bigger hydraulic roller, little more compression, and a way better head that goes 370 cfm and a drag pack intake. 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
