FINNEGAN MAKES THE FIRST RIP IN HIS BLOWN LS-SWAPPED GMC TRUCK! IS THIS THING TOO PRETTY FOR THE DRAGSTRIP?
There are a lot of vehicles that make it to the annual SEMA Show in Las Vegas every year that do not run and drive. At all. Or some that sort of do, but are far from ready to hit the track or the streets. So the fact that Finnegan and the gang got his OBS GMC pickup project done for the SEMA Show AND actually had it on the track not long after is kind of a thing. Not earth shattering, but still a big deal because lots of these projects end up sitting in the shop for months and months and months before anyone has the drive to touch them again after thrashing to get them ready for the show.
But Mike and crew got this truck home, finished up the details that needed sorted to start driving it, and then hit the dragstrip to see what the blown LS could do.
Video Description:
We filmed Episode 331 a month ago, which means for once we are actually ahead of schedule. lol. It’s weird to even type those words. Anyway, this one is about the 1998 GMC Sierra work truck that Joe and I put together last October in preparation for its debut for the annual SEMA Show. While the truck ran and drove into the show and looked great, it was far from really being finished and road-ready.
Before we could have real fun behind the wheel we had to get the transmission tuning for the Gearstar Level IV 6L90 worked out. That required a few hours of time spent with Jeff Harris of Mo’s Speed Shop in Dallas, Georgia. Jeff plugged his laptop into the OBDII port of the truck and was able to manipulate the tune so that the truck would shift properly so we could drive at more than 1/4 throttle. While we haven’t strapped the shop truck down to the dyno rollers to see how much power it makes, we did road test it and take it to our local 1/8 mile dragstrip to help donate toys for local kids who didn’t have much for Christmas. Hope you enjoy the video, our next one will be about prepping Blasphemi for Sick Week 2025. -Finnegan
