Did I miss anything at the party yet??? I've been working on the T most of the afternoon, so I hope I'm not too late. :)
I received a new Griffin radiator yesterday, so today seemed like a good day to install it. I'd been having some minor overheating problems with the OEM type 66 Mustang radiator that I built the car with, but replaced it with a super duty unit built to fit a 66 Mustang for easier installation. it's the 2 x 1.25" core aluminum variety, good for up to 600 HP, so I figure that should do the trick :cool: .

The first order of business was to make new mounting tabs to bolt the electric fan to. I never liked the wire tie method, and sure wasn't going to stab anything through my new $500.oo+ radiator, so after due consideration I decided I may as well incorporate the mounting into a full fan shroud.
The new shroud was fabricated out of 18G steel, as that's what I had laying around. most of it gets cut away anyway, so weight really wasn't going to be a factor. The center fan opening received a rolled edge, but I'm afraid the cold weather today forced me to toss the buck in the wood stove before I took a picture of it. it was simply a piece of 1x12 pine that I cut a circular likeness of the opening in, and then routed the edge over. with the tin clamped to the buck it was a simple matter to hammer the edge over to form the rolled edge. this stiffened the tin shroud a lot, as well as making a nice transition for the air to flow around. 4 studs were also welded in to mount the fan to.


The shroud was to be pop rivited to the radiator frame, so some 1/4" weather sealing foam tape was first stuck around the edges to seal as well as to protect the aluminum tanks from the steels edges.

A coat of trim black went on the steel shroud, but the rest is just too pretty to cover up. + why add insulation to the aluminum!!

She dropped right in as it should. the extra thickness and height makes it close in a few places, but nothing that posed a problem.

and my shortened model A shell still fits over it with ease

and covers the radiator by just - that - much. (thanks Max)

I'll let you know if it works tomorrow if the sun comes out again ;)

Good work Russ,

I hope this cools things down. A shroud with a really close fit is about the only thing that keeps the tiny cut down radiator in the track nose.

Say Bob... Solid motor mounts in that car?

Nope, angled downward isolated mounts.
