It has the 5.7 & 5 speed manual in it. Has 188k miles and is getting close for an overhaul.

Let's assume I already have the LS1 or LQ9, 6 speed trans, clutch/flywheel, & wiring harness. Would it be worth it?? What did you guys end up spending on your conversion? How about swapping out the gauges/cluster & using either the LS1 gauge cluster or LQ9 gauge cluster? And last, where's the majority of the expenses go on the drivetrain stuff (rear end, axles, driveshaft, etc)? Basically, what can I keep & what needs converted?

Thanks!
