I dunno about all this 5.7 hemi swaping. I have one sitting in the shop floor right now that I pulled out of a truck, I thought about putting it in my old shop truck (79) but it will cost more to get it in and running than I want to spend. I can freshen up a nice 318 or 360 magnum roller motor for the cost of all the swap parts. Its just me but I think I will just stick with my LA based motors.
