Info on engine, exhaust, and airbox.

The completed 496 Stroker engine with the Weiand 177 Blower. (The engine was completely rebuilt during the summer of 2002.)

A few details of the setup: The engine has Eagle forged steel crank, Eagle H-Beam rods, ARP bolts, SRP forged aluminum blower pistons, Melling high volume oil pump, ported and polished Edlebrock Oval port aluminum heads, port match to the Weiand blower intake manifold. The cam is a custom ground Comp Cams flat tappet cam. 230 intake/248 exhaust duration at 50 thousands. 0.558 intake,/0.561 exhaust lift. (A slight variation of the Comp 274NX blower/nitrous cam.) The engine is internally balanced to 8000 rpm. It has ATI harmonic damper, and TCI flexplate. Ignition is the MSD 6-BTM (Boost Timing Retard), MSD Pro Billet Distributor, and Crane Fire-Wire ignition wires. The carb is a Holley 870 CFM Street Avenger. The water pump is an Edelbrock high flow aluminum type. The transmission was rebuilt by PTC as a street/strip version with the 34 element sprag upgrade. The headers are Edelbrock. A few items give the truck away as not being entirely stock: the 4" cowl induction hood, the side exit cutouts, and the dual-dual exhaust, but otherwise truck basically appears stock.

Passenger side view of the newly built engine.

The exhaust cutouts exit on the passenger side just below the bed/cab intersection. These are fed by. A pair of Dynomax Race magnum mufflers to dual mandrel bent 3" pipes. When the cutouts are closed, the exhaust continues on to a pair of Edelbrock Performer RPM, 3" in, dual 2-1/2" out mufflers.

Another view of the cutout setup. Lots of fitting/cutting/welding and skinned knuckles. And…Lots of hard work! (Note the drive shaft loop on the right side of the picture)
