[QUOTE="decipha, post: 16142831, member: 74327"] I would highly recommend you keep your current engine. Don't bother with any ford 2v or 4v heads as they simply just don't make any power. Toss yourself a set of trickflow heads on it and get yourself a nice set of cams from mark over at bullet. I have yet to ever tune a single 4.6 tfs headed engine that made less than 370rwhp n/a with the smaller tfs head (non cnc R head) combos mind you. Most are in the 380rwhp range and I have done some that just tickled 400rwhp on 93 pump gas. If you want to go big bore and toss the trickflow 195-R cnc ported heads you can pick up even more power. For reference, my 5.4 with trickflow 195-r heads in my 02 harley truck made 454rwhp naturally aspirated. Be sure if you do go that route you get with mark at bullet as the R heads and the regular tfs heads have completely different cams due to the aftermarket head design of the R heads. Mike over at LMengines can also cut you a set of cams as well for either head. I wouldn't recommend any other cam grinder as most aren't familiar with the tfs heads needs. [/QUOTE]
