Hemi Swapping a perfectly good 70 Duster
For those not following along on my build thread, I'll highlight some of the G3 Hemi swap specifics here.
Here's a quick background. 70 Duster I've owned since 1997. I use it as a cruiser, and autocross. It's got a 408 LA in it with solid roller cam, indbrock heads and port EFI made by yours truly. 5 speed Tremec trans and 8-3/4 rear. Complete with big brakes and wheels to piss off the purists and make it stop and turn well on the autocross. You can find more info and pictures on my build thread linked in my signature.
The title of this thread is slightly misleading as of 2 weeks ago. I was working toward the hemi swap and planning to start later in the summer. Well, my 408 killed a roller lifter, so the swap has been expedited.
The engine is an early 5.7 that was supposedly low miles. I believed it was once I tore it down to find all the bearings looked like they came out of a box. The cylinders had zero scratches and hatch marks from top to bottom.
I re-assembled the engine with all the parts that came out with a new set of rings and a high pressure/volume melling pump.
For the heads, I did some hand porting and reused the stock valves with a fresh lap job. The camshaft is a Cam Motion Titan 2 with the recommended springs and hellcat lifters.
Once it was assembled I started making it pretty.
I made my own harness and it will plug into my existing firewall connector. Should be mostly plug and play.
