Check out the November 2002 issue of Super Chevy. I cant remember the page numbers, but look for articles titled "Proof Positive" and "In-Nova-tion". In the first article, they show a build-up of a 414 CID small block that should make 1000 HP with a Procharger. Im not sure which model they are using. In the second article, ATI took a 502 crate engine, ported the heads, changed the cam, installed a dual quad Offy intake, two Holleys, a D-2 Procharger and made 1204 HP and 1020 LB/FT of TQ at 6200 RPM! At 4000 RPM, this thing was making NEARLY 600 HP and NEARLY 800 TQ. It made 1000 LB/FT of torque from 5400 to 6200! All this on a STOCK BOTTOM END (except Cam).

They also metioned a 427 BBC/F2 blower combo that supposed to make more HP. I'm assuming that they are referring to the 1350 HP beast advertised in the recent ProCharger ads...

CHECK IT OUT!!!

 

BTW... they did this on 91 octane!!!
