Re: 72 Blazer project. OMG

I installed an ls3 4l80e swap in my 72 but kept the original frame and axles. I had the original 12 bolt and Dana 44 rebuilt. Installed an offroad designs 3” lift with softer springs. I adapted the NP205 case to the transmission and kept the stock location for the t case. I moved the engine forward and only oblonged the forward holes in the frame. I bought a bolt in engine crossmember that didn’t require new holes to install. I tried my best to keep everything stock on the frame so if needed it could be put back. The dash isn’t even cut for a newer stereo. I have to say the ls3 runs really nice and cruises down the highway at 2000 rpm with 373 gears. 33” tires. I wouldn’t ask close to what this guy is asking and mines cleaner and a Highlander to boot.
