Okay I am a rookie here so feel free to give the appropriate "smile"... I have a FJ55 in the shop with a brand new rebuilt Chevy 350, and the shop owner is guessing at the right radiator, but isn't really sure. What I have right now is a shot 1966 - 67 Buick SkylarkMOD - 433347 radiator. He suggest putting the same one back in, but I think it might be the culprate of the old engine blowing... I plan on using the Pig for pulling a boat up some moderate mountains/hills (depending on where you live)...East coast they are mountains... It also has an after market A/C. Has anyone put a 350 in and had success with a particular radiator? Any help I would greatly appreciate. Thx.
