How to test 5.7 hemi?

Fuel Injection vs. Carb.

If you buy everything new. The cost of a carbureted hemi is about the same as running fuel injection:

Mod Man Intake 400.00
650 CFM Holley 400.00 to 600.00 depending upon version
Hemi 6 Ignition Controller 475.00
Wiring Ignitions Wiring Harness 186.00

Total 1461.00 to 1661.00 + Tax Shipping + Fuel System

For 400 bucks more I'd go Hot Wire. Or you could do Megasquirt for the same or less.

I have a 2006 SRT8 computer sitting on the shelf (No VIN#), I'd be willing to sell.

Sharpen your pencil and do the math of all your different options. This swap isn't cheap or easy. (If it were it wouldn't be any fun.) The people who have the most success are those who spend A LOT OF TIME planning.

Give Matt Cramer a call at DIY Autotune and talk to him about MS3 on a hemi.

Best of Luck,
