Heater Core Replacement

I'm replacing a heater core for a 67 non AC small block. The core in the car was half an inch bigger than the one that I received from Classic Industries. I did read that the dimensions changed half way through 68. The bends in the tubes are slightly different. Is it advantageous to go with the bigger core? I'm not sure if the core that I pulled out is the original.

Re: Heater Core Replacement

Philip, This was hashed out a few years ago. Here's a link to the thread with pics. I think you need
Classic's H2298 core which is now 3013319. It seems this core is listed by other suppliers as used
on early 68's. I read on another site where a guy got his at NAPA.

Unless you're doing a correct type OEM car, I'd do the big block modification since you have it all apart.
Looks way cleaner and the hoses don't interfere with the valve cover.

Re: Heater Core Replacement

Well bufford heres my two cents worth. The stuff they make today is all aluminum and its junk compared to the original unit. If you have a radiator repair shop in your area take it there. One have them boil it out two have it pressurized to find all the leaks and repair them .then ask them while they are at it to reenforce the water necks at the core with extra solder. You will get another 30 p[lus years out of that old g/m core. The general made good stuff back then and they will never again give out so much brass copper iron and steel at those prices again . Just another way to solve your problem. Hope it helps good luck .alex

I agree with this, I did it as well.

I can't complain, but sometimes I still do.

Re: Heater Core Replacement

I would see if you can get the original re-cored by a local radiator shop. A lot of the replacement cores are cheap Chinese crap that will end up leaking again down the road.
Just my opinion.

Re: Heater Core Replacement

Also, if you have a core rebuilt, either have shop show you it's good with pressure test or test it yourself. I had one "refurbished" and decided to check before installing...glad I did, it leaked at the tube joint when I applied pressure. It has been awhile (a few years), believe I used 10 to 12psi to check but not sure. Reading online it seems the system runs around 14psi.

Would be a major bummer to reinstall then discover it leaks.
