    I plan to replace the factory 22’´ rad on my 1965 chrysler 300 383 2 barrels

    First option: 26’’ cool casse MOP757A, does the trans line will fit?

    Second option: wizard coolind 22’’ bolt on rad (more expensive)

    The factory 26" rad used a different radiator support. You would need to drill new mounting holes in your rad support to fit a 26" radiator. Your cooling system would hold more coolant, but the opening for airflow would still be 22".

    For awhile it was popular to mount a radiator from a Ford Explorer. I think you needed the rad from a V6 explorer with the upper rad hose from a V8 Explorer, and use your original lower rad hose, or something like that.

    IMHO, I'd go with the 22" rad that's ready to go. Unless you are out in the desert and having over heating issues, the 22" will work just fine. Bolt it in and be done.

    If you go with the 26" rad, you'll have to cut and drill the rad support. If you are worried about trans lines, then doing the rest of the work correctly is going to be a lot harder to do... and once you do it, it's hard to go back. Then you have to screw around with getting the right hoses and possibly changing the water pump housing to orient the hoses to the correct side. It can escalate into a bunch of work that will have negligible results.

    Is this even a question and if it is what you trying to say? If the company installs the fittings where they should be, yes, the tranny lines will fit that radiator. I guess that's the answer your lookin for? Good Luck

    Why not buy the correct part for the application? It costs what it costs. In my experience, trying to "make" something fit to save a few bucks usually winds up costing more in the long run.

    Matt,

    I replaced my steel transmission lines with flex hose lines so it really doesn't affect mine. Most of these guys are more knowledgeable than I am so I would go with the 22" if that's what they recommend.

    Is it okay to run 16psi instead of 14psi (I have no AC) ?

    btw, that $399 price is our List price that you found on our website. I realize you already got the smaller ECP unit but I just wanted readers to know that we charge list price on our website and if you go through one of our dealers, the price should be around $357. Further, as a forum member, if you PM me, I'll shoot you guys a special member price.
