Hi Guy's

Can anyone tell me if this combo should have an expansion tank connected to the radiator or not.
The car does not have A.C

Just looked it up in the NCRS Tech manual. No expansion tank for a 68 big block with or without a/c. Unless it is an L88. That had one.

No Corvette had two radiator caps. Lots of guys have added an expansion tank but it's of little use or function.

Thanks for the quick replys that answers that. also something to remember for future that 2 radiator caps is a no no

My 68 does not have one

My 68 bigblock does have a correctly dated Harrison expansion tank and my radiator has a cap also, which only proves that Bubba has worked on my car bigtime. I wonder if at one point it was going to be an L-88 clone... I mean, why a correctly dated wrong part??

Easy Mike

Your 68 should have a four row Harrison copper/brass radiator with a cap; no expansion tanks with these radiators.

What you have to remember is that bubba has had 42 years to work his magic and boy has i think he worked overtime on my car
