4.2L mod question

[machoman013]

If ever in the event my 3.8 blows, is it possible to still use my basic bolt ons like the UDP, (assuming exhaust as well), intake spacer, and cai if I swapped with a 99+ f150 when I'm an 03 3.8L? I know it'll take other modification and needs for parts to, but I wouldn't want my other mods to go to waste.

The 4.2l is in essence the 3.8l but with a different crankshaft. When you swap it over youll put all your mustang stuff back on to it. It will all fit as its nearly the exact same engine from the outside.

Depends on the year of your Mustang

Yes you can use most of it, the upper half is pretty much the same its the internals that differ.

Ok here's the dealio. If you have a 94-98 V6, you can directly swap over UDP if you use a rotating assembly from a 97-98 4.2. You still need to use the 4.2 balancer, but the pulley can still be the UD one. If you buy a later rotation assembly, you'll need to buy a late 01 UDP. You'll also need to buy a late 01 oil pan and pick-up tube, because of clearence issues. If you have 99-early 01 V6, you need to buy a 01+ UDP, you might be able to get away with using your stock oilpan/pick-up tube, but that's your call not mine. If you have a late 01-04, you can swap over everything literally since both motors are internally balanced. This should clear up some questions.
