There is a thread or sticky that touches on the major details on swaps ect....
I just put 14mm GM 550cc on my set up, I bought a pallnet fuel rail and the injectors were $65 a pc.
I had to modify the injectors a slight bit to get them to go in but it was really easy, probably took about 10 min (every injector different). I was able to use the seal kit for 14mm from pallnet as well (square seals for the bottom just like stock) . I also had to buy 25c ea E clips (Ace Hardware) to keep the injectors from going to far into the rail.
Just order your rail way in advance and dont get your hopes up on it being shipped until he gives you a tracking #, even if he says he did. lol
I can post pics if it will help.
