Does anyone have a dimensional drawing for a 26" b body radiator ?

[RyanSchoen]

Hello,

wondering if anyone can help me out? I am looking for a dimensional drawing for a 26" big block radiator for a 69 charger. Passanger side top port and drivers side lower port. I have found a couple partial drawings online but nothing complete. Mainly looking for the offset dimensions for the top and bottom hose connections. Appreciate the help.

I have to ask why? If your going aluminum, find out the brand you may go with and then ask what problems others have or did not have with it.

That's a fair question. I am having a custom piece made by a company that does not have an off the shelf radiator for a 69 b body and I do not have the original or a original style radiator in my possession to take measurments.

OK my stupid question is why not use a stock setup? It worked with 6 pack and hemi.

engine builder instructed that i do not run a mechanical fan. I have seen mixed reviews on the standard twin 11" electric set up that several vendors offer. So I decided to go all out and center this radiator around an 18" SPAL brushless fan that pulls more CFM than anyone needs.

Im just saying factory setup works. Is your engine stroked? Both my Bee 440 6 pack and charger 440 6 pack had stock with shroud. Not problems in SC heat.

I have no doubt in the factory set up, and yes my engine is stroked and makes 900HP. One of the most well known hemi engine builders told me to not use a mechanical fan on the motor he built for me and I'm going to listen to his advise.
This will also bring another radiator / fan option to the market for others to consider.

Probably a safe bet. The builder is most likely under 60 years old. If everything has been flushed correctly, you do not need all the extra stuff that was suggested.
CODICIL! I am referring to fairly stock engines. We have not had a overheating issue while going to car shows in Missouri, Illinois, South Dakota and Michigan.

You are probably aware that you will have to upgrade your electrical system for the electric fan setup.
Good luck with it.

They worked with me to make a custom design. That drawing posted above is almost the finished product My plan was to have it bolt into the factory location and use factory hoses. I should have the radiator in a couple weeks. Jason.Smith@pwrna.com will get you set up. Using my design would save you some money. the engineering fee they charge is steep for custom stuff.

Custom radiator finally arrived. The fan is massive, bolts right in like a factory unit.

Sorry, no pics of the final set up. 620 HP 500" stroker. Dual 13" Spals. Dakota Digital fan controller. 165 Amp power master alternator.
Some fine tuning on the controller keeps it down to 200-210 degrees on a 95-100 degree day. 80/20 water/antifreeze mix. Borderline heat issues.
The stock fan and shroud are the way to go if it will fit.
