DYNO s truly do show what your motor is made of, if you want to be sure find your happy HP spot and run it 10 15 times on the dyno to make sure the motor is solid. Taking a can of NOS and making a crazy number only to blow the motor to pieces when you go to use its just expensive, knowing with settled confidence that your motor is solid makes the label on the engine irrelevant
When running those types of rocker arms on older type Chevrolet aluminum heads, not a good idea, they always pull the rocker arm stud bosses out,or break them off. Run a good conventional rocker arm and put good set of stud girdles problem solved. If you need a offset rocker for clearance on pushrods order them as such for this application.
Something is not correct .... That head has enough flow with that camshaft to make 900 to 960 hp NA .... Even if you say 150 drive hp for the supercharger or that its actually making 1100 hp that is only 630 hp NA plus the boost... Its coming up way short of what it should be
Send the blower in to be serviced, it makes to much noise and not the right amount of boost. My 8-71 makes much more boost than that 14-71 under driven without that loud whistle noise.
Service what exactly? Your smaller blower would most likely register more boost. Boost is a measure of back pressure. The idea is to make more power with less boost. Air charge temps stay cooler. Anyway service what exactly?
Uh, an *unboosted* “572” is going to make a great deal of power all by itself. Only reason I can think to add a blower to such an engine is 1) competition, 2) appearances, or 3) some reason I cannot fathom, e.g. “I must have a blower, as I’m wanting a real life version of an A-Car truck, and those had blowers!”
Amazing work good job ❤
As usual, another solid video 👌
cool! Thank you

Common on Older heads..
That blower must be totally de-stripped. I think that engine would love some E-85 and tight stripping, if the valve train could handle it of course.
Well Always is a First Time so, 🤷♂️

That rocker system is totally inadequate for blown setup especially on the exhaust side
You said 11-71 at 38 secs 🙂
Was such a blower made? (Don’t they usually have even numbers for that first number, e.g. “8-71”????)
Pretty weak for 14_71 blower

If that's all the hp yall made on a 572 blown with a 14:71 blower then you should rethink of how you build motors....that's pathetic!
