Sheldon Brewer’s Dart has it all. Literally! That’s why it weighs in at a hefty 3705 lbs with him in it. Things like the full exhaust with power cutouts, cd player, and other creature comforts add considerably to the Dart’s race weight.  That’s a lot more than most race cars.

But with it’s pump gas 496, it runs consistantly in the 10.40’s. That’s pretty quick for a street car! And the engine isn’t some tricked out tempramental race piece either. Sheldon’s 496 is just a well put together pump gas combo. The 496 has a 4.150 stroke 4340 Crank, 6.760 4340 H-beam rods, and a custom Ross Piston that calculates out to 10.7 to 1. Cylinder heads are ported Edelbrocks with the springs, locks and retainers swapped out to accomodate the custom flat tappet cam. The cam is 263/273 @ .050, and has pretty good street manners.  An Edelbrock Victor manifold and a Quick Fuel 1050 (4150 based) carb round out the top end. This engine dyno’d at 654HP and 653lb/ft of torque. Dyno Results here.

A quick online trip to Wallace Racing’s HP/ET calculator, show’s that Sheldon’s car should run in the high 10.38 @ 129, which is pretty close to what it actually runs, so it looks like the HP numbers from the dyno and the real world all work out.  (So much for those that say we test on a happy dyno.)

The rest of Sheldon’s driveline consists of a 9.5″ PTC converter spec’d out to match the custom camshaft, and  4.10 gears drive the Mickey Thompson DragRadials.
