340 cooling

Tuning has a lot to do with this set up.If you run lean, and mean, it could get dicey. I ran a 4 blade, with the stock rad, and never went over 190 deg. I now run a seven blade, 3 core rad, with NO shroud, and stay below 180 deg. If possible, I would recommend a shroud with your set up. My highs were recorded at an ambiant temp of about 90 degrees F.
