4.3 V6 in 85 4X4 Frame with 89 Body Mounted

[toomanytoyz]

As title states I have mounted a 89 GMC body onto my 85 3/4 4x4 Frame, This was done due to my 85 being a Snowplow Truck & the Body was Total Junk.

Im unsure as too whether to keep the 4.3 as all wiring in the truck is for this or to go with V8 & Change all wiring to match, I have the 4.3 & it would be nice to keep the FI. Just want to know what type mounting would be involved to put the 4.3 in my current frame, It is set up for V8 now. Are the V8 Mtgs the same for the the 4.3?

This Truck is used mainly to keep my lane clear in the winter as Im about 1/4 mile off road........................

Thanks for any Input, Rick
