Thanks Gary! The 428 HO dyno'd at 432 hp @ 5000 rpm and 502 lbft torque @ 3700 rpm with a real 068 cam and a true 10.75 to 1 compression through inferior flowing A-body RA manifolds with 2 1/8" outlets into 2 1/2" mandrel headpipes. It should make a little more torque & hp with the factory long branch manifolds. The heads are untouched and the block wasn't decked to preserve the select-fit piston letters stamped into the deck surface adjacent to each bore. The compression was made up with smaller dishes in the custom ordered pistons.

I have a dyno video, but don't know how to put it on You-tube and provide a link to it.
