What did the engine do on the dyno? Those big stacks sure do look good on there!

Dave,

It was run on the Dyno with an Air Gap and a 1000 hp Holley on it, and it made 775.5 h.p., and 740# of Torque (my engine guy is not set up for efi)-here is that Dyno session (btw, you can hear Harold Bettes from Superflow whistle, as he was present to calibrate the Dyno)-

100 0210 - YouTube

As most will agree, a Hilborn adds up to 10% on a normally aspirated engine and tremendous throttle response, so I think it's somewhere north of 800 h.p.-

The combination is:

-new 502 Block w/arp studded Mains
-Eagle 4340 forged Crank
-Eagle "H" Beam 4340 Rods (w/L19)
-AFR 315 Heads
-Isky Roller Cam (248/252 .680 lift 110 lsa)
-Crower Enduro Rocker Arms
-Manton push rods
-Morel Roller Lifters
-ATI SuperDampner
-Mahle Pistons
-Finally ended up with a modified B&B Oil Pan
-it had some extensive work on the Oil system-the oil pressure stayed between 64-68 psi from 45-6400 rpm
