Hydroboost brake booster with all lines - the vacuum booster is too big and will not clear the 4.6

Transmisson - You need a 4.6 transmission. They had 4.6 specific bellhousings built into the case..... even on the manual transmissions.
Flywheel and clutch for T-45 and 3650 manuals
Flexplate for 4.6 auto trans 4R70W
Driveshaft - 4.6 has a specific yoke that is not the same as any 3.8 yokes. Tubes are the same length, in case you want to swap only the yoke.


Probably some other stuff. Unless money is not an issue, I'd sell the V6 and just buy a GT. Others will chime in. Welcome to the forum.

 

Welcome to the club, it's a lot of time and money to just do the swap, save up for a month or two, sell the v6 and buy yourself a decent gt. less hassle, unless you want to take up the build.

 

i have a 1994 v6 3.8 liter mustang , i want to put a 1998 mustang ?4.6 liter engine in. will the engine mounts line up from the 1998 engine to fit the1994 frame . or will i have to change the cross over member frame from the 1998

 

 

Going to be cheaper to sell yours and buy a GT. Save your money and time.

 

Did you not read the list of things you would need to make this swap posted above?

The answer is yes since the 4.6 was not even around in this platform in 94.

 

yes i have everything on list .just looking at the engine mounts on both the 94 & 98 i could see they where different.but the list that you talked about did not mention this

 

Plus a lot more since you are putting an OBD2 engine in an OBD1 car. You'd be better off putting a 5.0 in it, which was the V8 offered in 94/95.

 

You will need to swap over the k member from the 98

 

I'd save the time , and money ..
Not saying to not do it .. but you have to step back , and reaaaally look into this swap.
There are alot more things than just a simple engine swap with different motor mounts.
You have to take the computer/ harness / transmission/ rear end / etc. Into factor.

I'd just get a GT , or better yet even a Mach 1.
