    BUILD THREAD 86 GP 2+2~Blown 6.0

    Took the car to Rock Falls yesterday for a test session. Trailered it as I now have access to a decent trailer and pickup and didn't want to mess with breaking at the track first time out on a new setup with a toddler at home. Since I don't have a roll bar I'm limited to 11.50 for sick summer...

    picked up a rough 87 Grand National - how to approach project?

    1. Pressure wash it off an make sure it doesn't get wet when it rains, fix leaks into interior if it does leak so your interior doesn't get ruined. Fix hinges or latches as the thing is pretty rusty the doors are probably out of alignment or hinges worn and hard to close. Replace any worn or...

    Questions about pulling an LS motor

    03+ you can get tach but no oil pressure or coolant temp. I guess you can swap to a 98-02 oil pressure sensor and leave the OEM wires dangling and pull new wires to a 98 style coolant temp but yeah, its possible to get there but its more work. There are a lot of added costs (IMO) to get a...

    Questions about pulling an LS motor

    An AWD gmt360 v8 is probably the hardest LS donor. A 5.3 is a tight fit in a chassis that was honestly designed for an I6. I had a 5.3 rainier for over 100k and worked on it a lot so am pretty familiar with the chassis. TBSS also get a bad rap because they are so hard to work on. The front...

    Retrosound DIN 1.5 bluetooth head unit install experience?

    radiator options for LS swap?

    F body rad sucks because it lays down at a 20 degree angle and the rad fill cap is tilted. Do you want to run a drivers side inlet or dual pass? I have a griffin dual pass which is clean as the inlet and outlet are on the passenger side so you can get away with a short upper hose vs something...

    Charging ac in g body

    They also come up with a new refrigerant about every 20 years, almost like the patent runs out and they have to come up with a 'new' freon because the old one is not longer protected by a patent I mean miraculously turned bad for the environment.... It's also funny how the govt locks down...

    Pontiac OHC-6 SPRINT parts on fleabay

    The OHC6 pontiac is one of the coolest looking engines of the 60's GM family. I almost bought one probably 10 years ago that came up locally on CL, however the owner wanted to keep it attached to the rolling rusty hulk of a 4dr tempest that it was bolted to. I stumbled on video of one with an...

    Does anyone here regret their auto to manual swap?

    I put a t56 out of an F body behind my LS in my GP and have about 20,000 miles on the setup. The swap was a bit of a pain, mostly with the hydraulic pedal because I built it all myself out of other GM vehicles (S10 clutch pedal, 3rd gen F body master cyl). I also run a pretty aggressive clutch...

    Diddly squat update #4251.56 Put the shop back together Dug out one of the spare parts I had. I had traded a pair of decent grey belt retractors a few years ago with the goal of replacing the passenger side on the cutlass because a mouse chewed a hole through the belt. I had the drivers side...

    4x4 4L80E to 2wd

    electronic speedometer conversion

    G van or C/K pickup/burb post 88 are your only options for factory swap parts I tried putting a G20 cluster in my GP gages but it was way different. I ended up with a summit electric speedometer and mounted it to my column like a tach Alternatively you can get an electric in to cable out...

    Finished the wiring oops repair and took it to the coin op wash to remove the 16 months of mouse blood and urine. Also took it for a short drive and seems good! Its a bit rich at idle but not bad, quick hpt update and should be good. Besides the cam having a bit more chop everything seems...

    Ended up giving up on the idea of the spacer as there's only 1/8" between the blower and the hood and I'm not rebuilding my motor mounts and exhaust this late in the game. I can only run 11.50 legal at sick summer anyway and it's already been 11.10 so I have enough power to get done what I...
