Hey there i need to pick some brains. Dodge is something i am very dig on but i have had alot of problems with my 2003 ram. I have taken to deallers and i have taken it to a home town mecanic and i cant figure it out the truck runs like crap. I am looking at putting in a hemi. what will this intail is my tranny compatable will i have to change motor mounts and will i be able to simply change the ecus or will i have to combine them. im also a import man and love chevys i have only done something like this to a chevy. dodge guys help me out because i love my truck but im at a brick wall with the truck that i dont think i have any opp without rebuilding the 4.7. so can this be done.
