Richard Conley is building a 407CID/500HP AMC engine which will be mated to a T-10 4 speed. Starting with a 1969 390 block and dog leg iron heads. Parts include J&E forged pistons, Crower Cam, Crower Stainless Steel Rocker Arms, ATI balancer, MSD ignition with 6AL, Herman Lewis Intake (Thanks Mark). The heads were ported by "John the porter" and stainless steel valves were added. The rotating mass (crank, pistons, rods, flywheel and balancer) was recently balanced so we are ready for final assembly.
I will also be installing the cool Meziere Electric Water Pump
These are the results of the sonic test on the block. It's bored .100 over stock and number 7 cylinder has been sleeved.
