I have 92 c1500 700R4, just lost 3rd and 4th. I’d like to do a stage two build with plans to drop a 383 in it later down the road. It has a stock 350 in it now. Is a performance build possible with the stock motor in it now? Any suggestions on master rebuild kits? Stall on torque converter? This will be a daily driven truck. thank you
