so im kinda working backwards, I installed udp, cai, throttle body in the summer and just did headers. I was going to do cams this winter aswell , I was gonna stay away from FI because of cost , well changed my mind, edelbrock kit looks pretty good , the 500 dollar rebate helps , sell udp, cai ,thr body, still is a lot of cash. I would like to know if there are reasons for not choosing edelbrock?
