wanting to swap a few 6.1 parts onto my 5.7

Cool Hand said
Have a 6.1 I was gonna put in my duster, but it turns out it needs allot of work. It was a theft recovery car so I guess they beat it pretty bad. Anyway I decided to go with the 5.7 I have instead. Was reading about the intake swaps a few people have done,and would like to do it for looks mainly. don't like the 5.7 plastic intake. Looks like I could also gain on the top end This is by swapping the intake, injectors fuel rails, and throttle body from the 6.1. I guess my big question is can I swap the coil packs from the 6.1 to the 5.7 to get rid of all the plug wire mess? The 5.7 is an 04 and the packs ,and plug wires are all over the top end of the motor looks horrible. Is this possible gonna be running holley terminator x harness.

This is my 5.7 truck motor with 6.1 intake. If you have eagle heads you can bolt the intake on. If you have early heads you will need adapter plates like I have. The 6.1 heads will bolt on your 5.7. If I where you and you have the early heads I would use the 6.1 if they are good or have them redone. I have the 5.7 coil packs and shorty plug wires. You will have to use the 6.1 fuel rails and throttle body. The 5.7 will not bolt up. You can use the 6.1 crank and cam. Your 5.7 will run better than 6.1 with that setup
