hey guys, so been using the search function on here, well cause i know how to use a search bar...lol... anyways, was looking for info if anyone has successfully done a 4 valve swap onto a 5.4 in the van... do they fit?? ive got a line on a full upper end fromm a 98 cobra...from headers to intake mani...
im thinking of swapping over and getting a tune from Mike... anyone have experience doing this??? i dont want to tear the motor down just to find they wont fit, when i can ask on here and maybe learn from someone else who has attempted this.
id like to see 300+ hp out of this set up... and maybe just maybe one day throw a SVT supercharger on there.... idk just some ideas....
A junkyard V10 will give you 300+ hp and probably be cheaper . I believe my stock V10 is rated at 305hp.. plus I have a tune from Mike, another 20hp-ish...
