5.7 hemi into 73 Charger.... I need some information - 10/18/10 07:12 PM
Anyone put a new style hemi into an old mopar? What all is involved? I think i read somewhere that a smallblock 727 or 904 will bolt up to the hemi. What about converter? motor mounts? electrical issues? We're planning on making the hemi caburated if we do the swap, but what about spark and other hemi sensors? thanks- Andy

im also planning this.
Msd have something called the Hemi6 and with a harness from msd you have spark.
And offcourse you need headers and a oil pan(if you dont build your own.
I leaning towards a carb intake from xv motorsports simply cause they are cheapest.
I also plan on doing a custom cam cover simply cause its so darn ugly.
TTI have the motormounts i think.
As for flexplate you can use the stock 5.7 hemi plate if you just cut of the starter teeths.
As for upgrades for me it will be headers, 750 carb, some porting some wild hughes cam ,just to get the idle i like ,with matching springs.
I will also use forged pistons from mopar ~200$ and some aftermarket rods since i read somewhere that you will need to replace the rod bolts anyway.
And then some spray on it.
Aldough i have 3 more builds before this so i guess you could say im in the early stages.

Here's mine, 6.1 SRT8 Hemi in a 70 Road Runner. I wenth the motor plate route. I'm also using a Turbo 400 with a JW Ultrabell & Mopar Lite Weight Starter. I made my own headers & used a modified Milodon Oil Pan. I'm also using the FAST ignition controller. I should have it ready for start up this weekend.

Both Hot Rod and Car Craft have pretty good technical articles available online in the archives about new Hemi in old Muscle swaps
