Hey all, First mod was to remove the cast 4.8L and replace with LS6 Aluminum block with Magna charger w/Radix running 8 psi. I can't imagine how it would run with a 427 in it. Would be way to much to try and put to the ground. Anyone else unhappy with the trany ratio's? Definitly need to put in a T56 with aluminum flywheel. These trucks are a blast to drive!
