mopowergtx OP master Joined: Jun 2006 Posts: 3,075 Eastern Ohio	Just picked up a complete stock 1975 440 from fan blade to the driveshaft for my buddys 1967 Coronet 2dr Hdtp. His goal is 450 flywheel HP with stock HP exhaust manifolds and Eddie RPM intake. Stock iron heads and stock crank. Manual brake car so vaccum is not a concern. What do we need to do?

I'd be very interested in seeing the combo suggestions as well. 1969 Dodge Super Bee A12 (440 Six Pack, 4-speed, Dana 60 4.10) 1972 Plymouth Road Runner (400, 4-speed, 8.75" 3.23) 1974 Plymouth Duster 360 (360, 4-speed, 8.75" 3.23)

Scott you should be able to do it with big valves in the heads.Have Nick put big valves and bronze guides in and he will open up the bowl area to take advantage of the bigger valves.He can also sell you a Comp Cam that will match your heads.I would recommend a EXHL hydraulic grind and about 10.5-1 compression.

Get the compression up....9.5 to 10 max. Quality of fuel may be a problem--if you can build in some quench it would be a plus.

mopowergtx OP master Joined: Jun 2006 Posts: 3,075 Eastern Ohio	Yeah it needs to run on pump gas too. Whats a flat top piston at zero deck with stock iron heads end up with for compression? Yeah I was figuring a modern dual pattern fast lift flat tappet hydraulic cam. So 2.14/1.81's with a bowl cut blended in and port match should breath enough? This 450 HP deal would be a piece a cake with some Doug Headers, single plane high rise intake and a 850 Holley DP. This "stock" outward appearance stuff leaves me wondering if its possible. I mean we're leaving a bunch a easy HP on the table corking it up with that dual plane intake and iron exh. manifolds.

Flat top and 906s probably around 9.5:1, making some asumptions (7cc valve relief, 88 cc head, zero deck, .040" gasket)

Yeah I got 484 Purple in mine with a 2800 stall and 3.91 gears and its perfect. Probably better dropp down to a 2200-2400 stall with those 3.23's I bet. Dummy me.

Squeeze (CR) is one of the most important parameter of an eng's power potential. live every 24 hour block of time like it's your last day on earth
