Help with Cam Selection on 440 Dart? I have a race only 72 Dodge Dart, 3200 lbs with driver. I am building a 40 Over 440 with a 512 Stroker Rotating Assembly from 440 Source including their lightweight crankshaft, Trickflow 270 Heads, 10.8 Compression, Max Wedge Super Victor Manifold, Dominator 1050 Carb, 1.6 roller Rockers, mechanical rollers, 2" Hooker Fenderwells, Pat Blais 727, 4.11 Gears, 10.5 x 29" Hoosiers. Just getting back into racing after 15 years. I would appreciate your Cam selection recommendations, and welcome any advice on the build. Much appreciated. Thank you,

mid 270s @ .050 duration, 108 or 110 lsa.
.700 minimum lift.
Solid roller yes.

Could but I think the 108-110 will carry power higher up rpm wise.

Makes sense, I guess in a drag only car you mainly got to worry about the few thousand rpms between stall and shift points.
 
Call Jones Racing Cams, Bullet, or Oregon Cam grinders. LSA is a function of valve events not the other way around. I recommend consulting the professionals.
 
Mine is a Comp SR 264/268 @50 630. On a 108 in@104. Almost the same build. I have Indy EZ MW port, Indy 3X Dominator intake, 512 RB. Pulls hard right to 6300. Cam was spec'd by PRH/Dwayne Porter.
 
Sorry, forgot to mention stall maybe at 4800. I haven't purchased the converter yet, so advice on that is appreciated too.

Call a cam company, cross reference with what the converter company says or pick a cam , Dyno test your engine and have that info for the converter company. If you need a Dyno test over here in Yakima there's one available.
 
Call PRH/ Dwayne Porter to spec a cam. He's a member of the board here. I know this time last year cam cores were slim pickens.

What kind of service intervals do you want? Depending on the rockers you're using that will narrow your choices for a cam. For a 3 speed drag car you'll want the stall about 600 RPM below peak power. If you're using their best spring package 270 heads then you can get a pretty decent cam.
