700 r4 in a K20?

[Bigdav160]

I've done it too and used the AA output shaft.

Things I learned:
my factory 4x4 fan shroud no longer fit
the coolant hoses had to be modified
my A/C lines had to be modified
I had to move the shift linkage forward on the frame
I notched the front crossmember for crank pulley clearance
The transmission pan is really close to the front driveshaft but clears possibly because I have a 2" lift
The exhaust pipes had to be lengthened

Otherwise I would do it again
