Awe Damn, I actually read this entire thread..Course, I too am still waiting for my own '72 426 Hemi that was ordered and dealer installed in my own '72 Challenger, to get done at the machine shop...no pics, but The machinist stated that it should produce somewhere in the 2500-3000 HP range, on Pump 87, with 50 Degrees total timing all in @ 1200 Rpms...Also stated the engine uses a "3/4 Race" cam, with a Harley double pumper carb, "Pop up" pistons, and special "Gel filled" crankshaft whatever that is...He said it should really scream..I believe him too, cause he has an original 426 Hemi that came in a Dodge truck that he redid at his machine shop and MAN! that thing runs 14.00 at the local 1/4 mile track..
