sounds like a good swap. i was going to do a ls4/80e/205 and have another ls3/4l80e waiting on the shelf. at this moment i dont want to revamp the entire fuel system, do the wiring, and have the truck down for more time. so for now, its the ls6 with carb, th400, np205. and maybe i will prep the ls3 and 4l80e wiring, and have a tank already done with intank pump and all ready and waiting before i remove this setup later. that way the truck isnt down for long periods of time. at this point i want to drive it and enjoy it. but enjoy yours for the both of us with the overdrive lol. at this time its not in the cards for me. tooo busy

Cobalt964ruf · 09-08-2016, 02:11 AM

on a side note, with the dana60 front axle, 14bolt ff rear axle, both with lockers, th400, np205. and ls6 with minimal wiring and a carb, this truck makes a good SHTF truck.

72MARIO · 09-08-2016, 07:18 AM

I hear ya on the time. Just finished a lq4 /4L80 swap and kept it injected. Took me nearly 2 weeks of 12 hour days. The fuel tank was my biggest struggle. If i was to do another suburban of this era I would buy the ECE tank.
