2-199 heater core mod for single pass?

OK, I would not recommend buying the 2-199 (Caprice) so that you could then turn around and modify it to be like the 2-342(?), but since I already own one, it may become an issue.

So, has anybody modified a 2-199 to be a single pass? I can think of 2-3 ways to do it, but I'm not overjoyed with any of them. If you've done it, post pics!

Can you give me a high resolution pic of the core?

I don't have one handy, but it's the same core that GibletPlus uses. His pics are on the forum in various places. I can post one after I get home from work.

Hmmm.. OK.
I'll wait till you get the pics.

Are there enough benefits to make it worth the hassle of modding a 2-199?

I can see where this one's going....

And for an idea (maybe mine origionally even). Why not just add an outlet barb on the bottom tank for the pump to draw from, and then use both of the top barbs as inlets, even hooking up both the barbs on a WhiteWater or other dual outlet block.
Then you'd have great flow through the radiator, and get rid of the 'Y' fitting to boot.

Just a thought, I tend to have 'em once in a great while.

You could mod it, but the bottom tank is pretty thin. The barb would have to face downwards. If you really wanted to, you could build a res that sits under the bottom tank, and seal the tank and res together.

Hey Diggrr, that's a rockin' idea. For those that asked, here are the high res photos:

Sorry, this next one didn't focus well, so I just did a small version.

Use a piece of 3/4" tubing, squooshed <(technical term) flat to 1/4" across ID, then dremel a corresponding slot in the core's tank. Solder/JBWeld to your heart's content.
Good flow and a larger intake to your pump....

If you'd like a hose barb on the tube, just solder on a ferule (the brass ring in a compression fitting, available seperately).

Its an awesome idea to mod a caprice to run like a single-pass but remember if you already have restrictive blocks (pin-design and jet design) you won't benefit much from it as the restriction in block is so much greater than your double-pass cores. This also applies if you have 3 different WBs running...
