A few things if you are swapping in a V-8 for the L-6:
1. Don't have to move the trans crossmember
2. Don't have to modify the driveshaft
3. Don't have to modify the clutch linkage
4. More room in front of engine for accessories, electric fans, etc.

The only performance advantage is that it does shift weight toward the rear, so it can help handling a little bit.

When I swapped in the TREMEC, I debated on moving my engine forward. I was getting a custom driveshaft and the kit came with a new crossmember that I had to locate. I have enough room in front for the fans and whatnot. A little more clearance at the back of the engine would make changing plug wires easier.

Last straw was modifying the clutch linkage. Whoever installed the V-8 modified the L-6 Z-bar, and I would have had to do some fab to make it work in the forward position. Plus I would have had to mod my exhaust. Didn't seem worth it, so I put the engine right back where it was (I swapped the 327 for a crate 355 at the same time I did the TREMEC).
