Hi guys im pretty soon rebuilding an old 1971 340 with a thermoquad and iron intake and oem exhaust manifolds....is it the conception or the oiling/ cooling that does the overheating ? Some guys told me that an old iron 340 wouldnt stand a chance with a 100 c weather and 1 hour of traffic , is there a way to fix this ? I know that magnums overheat less but i would like to go with a 340 this time , all 100% original.

WHAT IN THE BLOODY HELL ARE YOU TALKING ABOUT???

LOL I'm kidding, but really, where did you get this info?

340 engines were and are a street engine. "Back in the day" I swapped a 340 into my 70 RR "was" a 6BBL 440 car. Drove the hell out of it around San Diego, LA. And when I got out of the Navy I loaded the thing down with all my possessions and tools, with a E body 'Cuda on the trailer, and lots of parts "and stuff" in IT and towed the thing all the way from San Diego to the N end of Idaho.

Overhead? The thought never entered my head!!!

When I got done with this I WAS BROKE!! (for awhile)
