it's a 5.7L GenIII Hemi. It came out of a cop car so it has a factory unlocked PCM and factory oil cooler. I had Basko Racing Engines do the short block (I ain't got that kind of time for measuring), the heads are a mild port/polish with Crower racing springs and valves with tri-lock retainers. The cam is custom grind from MyBois at Schneider Racing Cams in CA. Look 'em up, they're studs. Milodon oil pan to clear the rack-n-pinion front suspension I'm installing. I also picked up some valve covers from Mr.Gasket (same as the Holley but without the stupid "Holley" emboss), they're going to powder coat this week with the TTI (another fine SoCal company) long-tube headers.
The trans is out of the same cop car, factory trans cooler and HD solenoid. It's a NAG1, the issue is that these modern trans require 4 independent wheel speed sensors in order to manage shifting. The white-trash work-around from HotWire is to put a transducer on the drive line and convert it to a wheel speed based on the gear selection, and then split it 4 ways to send to the trans.
Hillbilly Power (tm) chops the IRS from the cop Charger and welds that bad motherfucker under the Duster, and puts wheel speed sensor on the IFS, thereby enabling factory shifting AND....wait for it...Anti-Lock Braking.
a factory 360/727TF setup in the Duster is 585 lbs of engine, 150 lbs of trans. The GenIII is 485 lbs of engine, 300 lbs of trans. I did my physics-math and that moves the center of gravity 2.11" BACK. That's gold for me, because I want to move the engine 2" forward so that the power brake booster on the ABS master cylinder will clear. Then I'm replacing the 8" dual-diaphragm booster out of the Charger with a 9" single-diaphragm booster out of a Sebring/Avenger. Otherwise, the Charger's booster hits the valve cover. But that double booster is for a 4500lb Charger, and the Duster will barely top 3200lbs - which is actually lighter than the Sebring/Avenger.
Thee trans is also "fatter" all the way back, so moving the bellhousing forward will give more room for the gas pedal and...wait for it...
the motherfucking COLUMN SHIFTER (which you can only get in a cop car) I've got a guy out in MA who does aftermarket seats, and we're looking to make a 60/40 bench that looks like a regular 1974 bench seat.
what else would you like to know?
