No doubt about mileage! What would happen if you took that mild 572 and put eddy performer rpm heads on it?
If it was mine, I'd probably do it with a puffed up 440-1 and intake and a big 4150 carb (the Braswell is awesome), fairly tight quench and a solid roller that keeps the dynamic compression in a happy zone for 93 octane.
Might even look into one of those lifters without needles for additional reliability........maybe the Isky EZ-Roll.
Shoot for 6000-6500rpm. To me, it makes no sense to build a truck engine.
If that thing didn't go 800+ with way too much TQ for street tires, I'd be surprised.

That would be an awesome engine. I have not heard of a Braswell 4150 do you have a link?
What would the power do if a roller cam was replaced with a flat tappet? With so much hp being produced, it might be a nice trade off in my application. I will admit I like the simplicity and ease of maintenance with a hydraulic flat tappet.

A 572 with standard port heads won't make much more power than a 440 with the same heads, but it will make it a lot LOWER! The torque will be fantastic down low. Probably the middle of the road head for this combo is a fully ported 440-1 head. You could set it up for max power by 6000 to 6500 rpm , max torque could be made to show up about 4600 to 4800 rpm, maybe a bit less. The B1 stuff is more rpm orientated, and will like more rpm so personally I consider the B1 heads a bit big but that is me. If I can build a 900 hp 528 cube motor with the 440-1 heads, You can build an 800 hp 572 street killer that will live a long life and not eat parts for lunch!

Check Braswell's website......if it's not there, you can give them a buzz. It's a spread 4150.
A flat cam of similar specs will obviously be down. How much is difficult to say. In this day and age of "naked" oils, some precautions need to be made to ensure longevity. Treated lobes, lifters that oil at the face and oil with high anit-wear additives, like zinc are good safety measures.

To be honest... I think you wasting your time with that many cubes and little heads... you would have a gas hog with a short rpm range that'll just blow the tires off at the low end hit.... JMO

WOW!! Any way you slice it, those valve covers and what is underneath them is impressive.
I do believe that I will have a 572 short block built by compu flow. For my application, a set of s/r's or 440-1's would do just fine. I am still out on a cam though as this short block will put enough of a strain on my hobby money. I could always buy some of the gingerbread at a later date.

would be a great street motor. with the right cam and heads.
If you were going to buy heads then don't waste money on edelbrock eddy... they are good but not for a 572.
call dwayne porter....tell him what you want to do...He won't steer you wrong.
I agree with this as Dwayne speced out the cam in my 493. Its a solid flat tappet and I told him I wanted an aggresive cam that makes good power as the lumpy idle does not bother me at all. And the idle is very nice and it works good. Dwayne is very good. Ron
