big block radiator

My 396 conv. still has a small block radiator. What is the best radiator to mtch my 350 hp engine with automatic transmission? I want to keep it looking fairly stock, though a little chrome would be great. By the way, why are there different radiators for manual vs automatic trasmission?

Re: big block radiator

some radiators for automatic transmissions have the trans cooler in them and/or have provisions for trans cooler lines built into them. That is why they are different.

Does your 1968 have factory a/c? If so it should have the "big" block radiator. If not then a 4 row/4 core copper & brass radiator will do just fine for your 396. That's what I had on my first 1969 Camaro years ago. The 4 row/4 core copper & brass radiator will "match" the look of the era

Aluminum will work as well. Just don't overpay for one. There are several good manufacturers of aluminum radiators. I have aluminum in my car now.

I like both copper & brass radiators and aluminum radiators.

Re: big block radiator

Griffin radiators have die stamped end tanks that resemble the stock radiator when painted with radiator paint (not a rattle can of black enamel), as compared to the equally effective in terms of shedding heat fabricated end tanks of BeCool and others.

Re: big block radiator

Here's a look at my new Griffin. I cut off the mounts because I built a tray for my radiator to sit on, like '70 and later GMs. This is an exact replacement rated for 600 HP except it's two-core, not four. (more efficient) The cooler lines bolt right up. Got it at Summit.
