1970 L46 Radiator Question
A friend just bought a C3 and asked this question:
"....does the '70 350/350 L46 have an aluminum radiator? It seems that some '70s did, maybe only big blocks. Is there a way to distinguish visually without removing the unit?"
Any help would be greatly appreciated.

Re: 1970 L46 Radiator Question (davidwp97)
if it's anything like '69 (which it should be) then it should have a 26" core copper radiator. Very early '69 L-46 cars had the aluminum radiators, but then they transitioned to the larger copper unit.
Then again, they may have switched back. Any '70 folks out there?

Hi,
If I remember correctly, the base engine in '70 came with the small aluminum rad with the separate expansion tank.
The L-46 and LT-1 came with the long 4 row copper rad with the tanks on the ends. I have that copper rad in my '70.
Not sure what the BB had.

My car originally had the L46 engine, and it has the copper/brass radiator with no expansion tank. As I recall, I looked through my GM Restoration Package, and found that the base engine was the only one that had the aluminum radiator with the expansion tank in 1970.
