I thought I would post some dyno results from an engine I recently built.
IAII - 505 w/ one of those 4.25 stroke $699 cranks. Here are some of the specs: 4.35 Bore - Ross pistons Eagle 6.8 w/L19 upgrade Comp Cam 283/283@.050 .747 lift (measured w/HS) Kaufman Hi port heads w/std pushrod location and 380cfm option. Installed as received. Harland Sharp 1.5 roller rockers, Roller lifters, 3/8" Smith Bros pushrods Edlebrock Victor intake. Carb used was 1250 Holley from dyno shop - made more than customers 1050 by 14 tq and 28 hp. This engine wanted the 1250! MSD distributor-locked in@32. RPM TQ HP 4700 675 604 4900 685 639 5100 687 667 5300 700 707 5500 696 729 5700 687 745 5900 679 763 6100 671 780 6300 661 793 6500 649 804 6700 636 811 6900 617 811 7000 607 808 Stopped here!

Thank you for the nice complements! The compression ratio was 13.7:1. I used the 64cc version. The Victor intake was cleaned up on the top and intake seperating fins and opened up on both the top and bottom to match the hi-ports. VP C12 racegas was used. It's going in a '73 Ventura - Bill -

One other note on Bill's 505 build.... this motor did not have a vacuum pump and was minimally optimized. I bet there was 30 easy hp left on the table. Impressive HP/$$ for a Pontiac.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
