The eight cylinder truck had the radiator moved back closer to the engine. If your truck was originally equipped with a six cylinder, you will probably need a shroud or some fan spacers or both to get the fan to pull cooling air through the radiator properly. That being said I believe the stock rad in good condition should keep a 350 cool, hope that helps. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | X2 what 3B said, especially the shroud if it was originally a 6, then a good '57 rad with a 7# cap will work fine

As was mentioned above, an original-equipment V8 radiator in good shape should cool a stock 350 without much of a problem. If you add some "go-fast" goodies to it, you'll definitely need some more cooling capacity. The 600+ HP 350's we ran on the circle track needed a pretty hefty aluminum radiator, a good shroud, and a high-flow fan to keep 'em cool.

I'm using a stock radiator with a shroud and have absolutely no overheating problems - even in the 100+ temps we often have. | | | | | Joined: Jul 2009 Posts: 33 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2009 Posts: 33 | my truck had original 235 6 cyl if that help ill try the original an go from there thanks guys for the input an help
