Engine swap

[Texasmustang]

On a 86 mustang with originally a v6 car. When putting in a 302 do you need to change the k member to a v8 or will the v6 work the same. Reason I ask is because I left the v6 in mine and it seemed to shift everything forward like a half inch to a inch. And I am wondering if that is throwing my drive shaft angle off causing the 65 + vibration. I have had the drive shaft balanced new u joints swapped out rearend thinking that was it. But it is still doing it.

IIRC the v6 k-members are different...

So guess that gives me a reason to look for a tube one lol. Think that's the reason for the vib. It is throwing the drive shaft angle off

I don't think thats the reason . I have done more than one swap with the v6 k and had no issues . My 86 vert was a v6 and now has a 351 and I have no problem . I couldn't tell you if there even is a differance between the 4cy , v6 and v8 . The i6 is different but I have swapped v8's onto both the v6 and 4cyl k's with no problems .

I'm gonna try taking the crossmember loose and jack it up and down see what happens. If the same I am putting my 8.8 back in and drive it till it breaks

Ur good! I did a 5.0 swap on my v6 and it fit perfect!!

Yea mine fit too just put everything bout a inch forward then normal and made the tranny sit to high. I put a 86 f150 tranny mount under it and the vibration I had at 65 plus is barely there. So I am happy now
