hey bill,
i finally got to strip down a 3V motor. though it wasnt a 4.6, a 5.4. be careful if you ever have to remove the cam gears. theres some preloaded reluctant wheel held on by very weak dowl pins which can come off when reinstalling the gears or even taking them off. other than that, a pretty typical mod motor just with an extra valve.
as far as building another mod fox, maybe if i had the time....but its one fun daily driver! i wouldnt mind getting my hands on a lightning motor/harley d. sc or maybe someone in my island will wreck their ford gt beyond repair and be able to salvage that motor. oh well....i have no time to be spending on projects right now, gotta spend time with my family, the little one is growing up so fast. but will be putting a lift in the garage one day....will post pictures when the project is underway.
i guess it comes down to preference. i prefer mine very low profile, as to not to attract attention from the local popos. cut off the stock 4 cylinder tailpipe near the hanger and leave the 4 cylinder tailpipe out the back. though some fat tires and 4 cylinder tailpipe, may have pple thinking, what an idiot, a 4 cylinder with wanna be 5L tires. with the side exhausts, its nice to hide your true colors infront of your fat tires.
