Blown 454 in Chevy High Performance...
Nice little write up on them using a 454HO/Merlin heads.
They dyno'd a few different cams with the BlowerShop's 250 and 8-71 on top.
Don't remember exact numbers but...600+ HP with the 250 and 800+ HP with the 8-71

With the Crane HR-226 cam and 2% underdrive on the 8-71 blower they saw 797hp@5900rpm and 743lb-ft@4800rpm.
Switched to the Crane HR-244 cam with 2% overdrive and saw 825hp@6200 and 751lb-ft@4900.
Nice numbers but I wonder how it would last in a marine environment.
