hi all. my name is tosha and i have some questions for anyone whos upgraged a fj40 to a 383... we had a 350 and it ran great but we wanted more power so we bought a custom bluprinted 383 and now have major overheating problems. themostat is fine, have a brand new high volume aluminum water pump, 4 core aluminum radiator high volume catch can, all aluminum pullys to wic the heat and a oil coiler mounted under the chasis for maximum air exposure and all for naught. any ideas???
