Mean 5.9

445Hp @5900 rpm and 450TQ @4400rpm. Pretty stout!
Heads have our prep work done, as we did to the Chevy as well...just 2.02 x 1.60 valves and blending into the bowl...no other work was done other than milling the heads down to get the compression right with the KB pistons...we had to change the pistons because these valves and that cam will run the P/V clearance to nothing flat.
But we used a std piston, dingle berry honed the block, cleaned it and that was it! Pistons were out of the hole by .002 so we used FelPro gaskets.

Really easy build, Comp shelf cam (230-236 @ .050) and 1.6 rockers....EQ heads with LA intake pattern so we used LA intake...750 double pumper right out of the box with no jetting or anything!
