I will be running close to the same engine/trans setup. I have a th350 and a 350 all disassembled but it will take about $1500 to get it going and im trying to find something that's already running for a little cheaper. Tire wise i want to run pie crust cheater slicks mostly for the looks and those are like 28.5-29.5 inches in diameter. I put everything in an rpm calculator and it says i will be turning about 3200 rpm at 60. Do you guys think this would be an ok combo just for now? I have limited time as school starts in 2 weeks and i don't have a garage or shop to work in so it sits all winter. I kind of just want to get up and running for now and i can do the rearend swap down the road.
