Nope, not kidding!! I didn't say you couldn't, but it aint normal by a long shot. Your taking a BIG risk slinging "heavy metal" 500 cid engines to 7,000 rpm. ANY such motor will be a seriously "race prepared", money is no object build.
You cite ONE (or two) examples of a BIG cube SOHC motor (not common) where the horse power peaked at 6,600 rpm. Still, pretty darn high for a big cube motor. There are no rpm's listed for the other, mostly DEDICATED drag race only examples of big cube motors.
Would YOU turn a 510 cid motor to 7,000 rpm? Not likely any of us mere mortals will ever have a motor that big capable of that kind of rpm. WHO would build such a motor, that would acutally survive? It's a short list, put Barry R and KC on it.
Would Blitz have such a motor?? Well hell yeah, Blitz might.
Tommy,
I frequent a few other technical forums, THIS forum is about as deep as any EVER get when it comes to technical stuff and serious gear head talk. You will see the best of the best when it comes to cars around these parts.
...a lot of these guys are way over my head!
