Looking to purchase a friends 1999 F150 w/ a 4.2 V6 and cracked heads. Found out the trans will bolt up to a 4.6 and it was just replaced. I have easy access to a 4.6. Anyone ever done such a swap? I'm going to do my own exhaust work so that won't be needed from a donor but will I need much of anything else other than the ECU and wiring harness'? Radiator the same? Any and all info welcome!
Ah alright. thanks for the info. I managed to find a truck close to what i wanted.. but needs engine work. The way the guy explained the problem sounded fairly cheap to fix.. but not counting on that. Might just get it professionally rebuilt so i don't have to worry much about it. The truck itself is in pretty good shape and the price is right even if i buy a new motor for it.
