Moving Engine position forward on 4wd

[tjsblazer]

Hey, I have been gathering parts to do a driveline swap to a 5spd. I had planned on moving the Engine ahead to the front holes (about 3 inches) to help with the overall driveline length and shifter position of the NV4500. I pretty sure that is where 2wd Engine crossmembers mounted from the factory. I am noticing now that the front differential is going to be very close to the cross member / oil pan (probably why 4wd were set further back). All the threads I can find look like the trucks had lifts (4 inch or more) in them when they moved the Engine forward. I am planning on doing it with stock ride height. Has anyone else moved the engine forward to the 2wd mounting position on a 4wd truck with stock ride height? Mine is actually a K5 but I know trucks are basically the same in this area. thanks for any insight.
