J D Engine and Machine
Engine builder Jeff Dickey of J D Engine and Machine is always very competitive in our dyno contests, but we're not so sure he's in it to win so much as to make a statement. Consistently finishing well overall, the J D Engine and Machine entries are always at the top of the list in terms of horsepower and torque. This year was no different, as Jeff's nearly 500 cubic inch big-block scored 724.5 horsepower and 610.2 lb/ft of torque for the highest power score of the contest at 1334.7.
Starting with a '77 Chrysler 400 block, J D Engine and Machine machined the block to the necessary tolerances, installing an Eagle forged 4.15 inch stroke crankshaft, Eagle connecting rods, and Diamond forged pistons. A main girdle from Chenoweth Speed and Machine was installed for additional bottom end support, and a stock oil pan was modified and matched with a Milodon oil pump, fabricated windage tray, and external pickup to handle the oiling duties.

Topping the stout short-block, engine builder Jeff utilized the Edelbrock Performer RPM heads required by the rules, along with the Edelbrock stainless steel valves that came with the heads. The cylinder heads were ported for maximum flow, and assembled with Comp Cams PN 947-16 valvesprings. Harland Sharp 1.7 ratio aluminum roller rockers were utilized to actuate the valves, and an Indy 400-3 intake manifold combined with a 1050-cfm Holley Dominator carb handled induction. Resulting in nearly 725 horsepower and well over 600 lb/ft of torque, this impressive engine scored the highest combined peak power of the 2009 contest.
