Hi guys, been taking a break from the forums for awhile as my summer was invested in the next iteration of build for my 2003 QC 2wd hemi. Inspired by my hurt 545rfe behind what was a cammed pre-eagle 5.7 hemi with Paxton novi 1000 blower, I decided to bite the bullet and do it once, right and unique. This is the “Snotrocket”, powered by a fully forged and studded 5.7 based 392 stroker w/ ported eagle heads, boost cam from MMX, Paxton novi 1200 and meth injection all in front of an LS based t56 magnum! Home built, and asides from finalizing the cooling system, right about ready to tear up the pavement.
The build started by tearing the engine and transmission out of my 03, saving some accessories bolts off it but that’s about it for reuse on the new engine.
From a fresh 05 block, I assembled the motor using a Manley stroker crank, Manley forged rods with ARP 2000s, and custom diamond pistons cc’d for 10.3:1 compression with eagle heads. Next some eagle heads received a valve job and porting topped off by psi 1515 springs. Once the heads and mains were studded out, the timing cover and accessories from an 07 5.7 300C bolted up complete with a Paxton Novi 1200 unit. I picked up this unit as a kit second hand after some quick measurements found it would be a perfect fit in my engine bay.
Next came the transmission. I used a 130T steel flywheel from science friction, McLeod rst twin disk clutch, QuickTime small block mopar to ls t56 bellhousing, and srt 10 ram throwout bearing and master cylinder to complete the assembly.
Driveshaft was built out of 5 inch aluminum, strange engineering chromoly slip yoke and 1350 u joints. Rear end received 4.56 gears
Interior-wise, the clutch-brake-gas pedal assembly from a donor 3rd gen diesel bolted right in, shifter came from hurst and a mopar green shift ball topped it off.
Wiring was pretty straight forward, gutted my engine harness of all wiring associated with the 545rfe, just needed to retain neutral safety wiring (routed now to clutch interlock switch) and backup lamp feed. New reverse lockout solenoid wiring was run. 05 PCM flashed for manual.
Exhaust started with long tube headers then I built a dual exhaust with x-pipe and all 3 inch tubing. Both banks are monitored via dual wide band. Currently exhaust is dumped under the box with no mufflers, but thinking of going with two black widow 250s (or maybe magnaflows to be mainstream...) tipped out through the roll pan.
Hope you enjoy the build pics, and if there’s interest I can provide a parts list. Beyond excited for this to begin tearing up tires!
