So this might be a dumb question, what about the radiator, transmission cooler. Does the obs 98 oem work on ls1 motor or that has to be changed to new body radiator and tranny cooler. I have neen trying to finish this build of mine but i havent been able to touch it in 6 months cuz i was building my house ( lotta stress by the way) but my house will b finished in 3 weeks and i want to get back to getting my 98 2 door tahoe 2wd running. Cant wait to c how it will run being that the 2 door tahoe is shorter than a single cab short bed. I hope the 5/7 drop helps out too and 4l80e with 3200 stall. Any help will b appreciated. And maybe qualify to an up to 20% discount where i work. Thanks again.
