Great results! At your boost level, the engine should survive quite well. Bet you'd have hit 600 H.P. if the rpms kept climbing.

Bob, I definitely think it would have gotten close, I expected the cam to be small, but with the blower and good heads/intake it carried much higher. Not to mention the EFI just kept getting better as we drove it on the dyno. Fun little terror, idled very mellow with a smidge of chop to tell you it had a little extra, then when it came up it took off like a banshee
It was a Mexican block, good parts, I am sure it would have been happy above 6000. However, the owner was there, stated he'd never go as high as we were pulling, was happy as a clam, and we decided not to chase past a 6K shift point or so. IF it was an aftermarket block, we would have put the heat to it :)
If I do another, a taller/more gradual S/C elbow and an intercooler would certainly have taken it to the next level. The owner actually considered a second one and left me a 347 to go through that someone else did, however it's a much less durable combo, so it's going to end up N/A

What is max boost on that Novi system. How many pulley do they have

What is max boost on that Novi system. How many pulley do they have
22 PSI, but it isn't a huge blower, 1150 cfm max. They claim 775 peak HP, but not sure how they get it, and I doubt the ribbed belt would get close.
They seem to have quite a supply of pulleys, both ribbed and cogged. Although I said some things in the earlier post, I'd add a toothed belt to that list too
