The GM factory water pump on 89 c4 was recently replaced. Finishing up with LT4 cam swap on stock L98 with ported intake. Considering high flow pump . Will the gm pump flow ... gpm work ok with 2row radiator?
Yes, the GM pump will work. My personal opinion is that you are better off with a high flow pump like Flow-Kooler or similar. They make a big difference in the engine temperature, especially in traffic.
