[Grumpy old man]

It's your truck so you decide which way to go . But when I did mine I had to switch everything to the V8 position and found the V8 manual trans cross member off the parts board from another member . I had to change mine because it would have driven me crazy (crazier) every time I opened the hood and saw the V8 sitting in the rear holes with it's distributor up against the firewall knowing that it's not the way V8 trucks came from Chevy . Yes it cost more and involves more work and parts but Gm did it that way and that's a good enough reason for me.In the pictures you can see the V8 cross member is heavier and how it sits further forward in the frame
