Changing radiator support from 22 to 26

[bing69]

Sorry, I'm late for the game. I got the radiator support conversion piece and a 26" radiator. Plan on installing them next month in my 69 Roadrunner to take care of overheating issues. Does anyone have or know what the part number would be for a fan shroud that would fit the off set radiator? Thanks

It depends on what radiator you have. "66 & '67 had a different shroud than '68 - '70.

There no Brand Name stamped on the radiator or on the invoice. Aluminum from Auto City Classics.

I know this isn’t for everybody, but I cut out the support to put this massive 28” triple pass in to keep the blown Hemi cool on the street, I even had to grind the frame rails and no way it would of happened if the battery wasn’t in the trunk.
Has 2 pushers hooked sequentiality, into the sniper computer and works fantastic, I think I could add A/C!

How does it run with the snipers?

It needed to be tweaked by “our guy” but now the throttle response is like a light switch, instantaneous, couldn’t be happier!

Good to hear.

Looks nice, you did a good job.

Some times a good block flushing does wonders. If you flush and clean the rad, why not the block. Worked for me.

E-bay. There is a good article in Motor Trend .

I don’t always fully understand the reasons why the automakers build cars the way that they do but I dont recall ever seeing any car factory built with a radiator core wider than the support.

They should have built all cars with 26” openings and make the radiator mounting brackets to fit the radiators. From a bean counter perspective it makes sense, less metal, only 1 stamping die.

Running a 26 where a 22 grew works good. I’ve done it. Car ran exactly on the stat temp, without a shroud. The core support is a weak part of the chassis, I’d rather run a 22 hole for that reason anyway. It’s not a big deal to run it either way.

to get it straight did the factory have a larger radiator opening to accommodate the 26 inch rad? i presently have a 22 inch want to put larger motor in suggestions from the pros is to install a 26 inch with clutch fan. is there a modification piece to weld in while car is down?
thanks 1969 RR hemi converted from 383

Yes the opening was larger for the bigger rad. The aftermarket rad supports are ALL for the larger rads.

I took a sawsall and opened it up!

Another ( cut 2" out ) here.
I used my 3" wheel of skin removal .
Drilled a couple new mount holes and used 1/4" J nuts.
I did paint the cut edge.

Yes. Use this to make it look factory. It replaces the passenger side support.
