What would it take for 550hp out of a 396 BB?
Ive got a friend with a 55 chevy.. that has a 396/375hp block with oval port heads (oe) Headers(still no carb or intake) Compression is unknown.. but does have a good lump to it!
What combo of parts would it take to make 550hp with this engine?
Project JUST-N-SANE
84' Camaro Z-28, 355CID,9.0-1 compression, ATI procharger 9psi (over 650HP),T56 6 speed, 3.73 Motive gears! 11.70 at 122mph in the 1/4 while babying the throttle to keep the tires hooked ,with pump gas! (NOW INTERCOOLED)

500 hp from 396 easy
Punch it out .060 over. Closed Chamber Oval Port Heads, heavily ported. 9.5:1 Compression. Crane Cams Mechanical Cam, don't now the part number but it has .567 lift intake .590 exhaust 248/258 degrees duration @.050 108 Lobe Center. Victor Jr. Manifold, 850 Double Pumper from Holley. Headers must have a minimum 2" primary. I ran this combo in a full body 69 Camaro with TH400 and 3.31 gears in the rear. Drove it on Pump - ran 11.78 at 114mph all day long. This is tried and true old school horsepower.
