This may be a retarded question, but I need to know.

Is there any difference between an LSx and a SBC radiator? Difference as in shape (size) or connections (anything other than an in/out)?

 

I hope I don't make myself look internet, but, what the heck I'll say it anyway.

Transmission lines?

 

Yes, they are different. As for connections, the LS radiator has a fitting for the throttle body cooler line not found on old SBC stuff. Additionally, the primary in/out necks are located at different heights on the respective tanks (LS hoses attach more towards the middle of each tank, height wise; where the SBC is more of a true top-to-bottom crossflow).

As for size, the old SBC radiator on my Nova is much bigger than what's on my LS cars. They would definitely not interchange without some modifications.

 

Thanks RPM, that's what I wanted to know. I didn't want to go out and buy a nice aluminum radiator for my SBC and be SOL after I buy an LS.
