The factory radiator support is this big U shaped piece that pushes the radiator towards the engine while leaving all of this dead space. I used that as a template to create a radiator support that holds the radiator in the middle of it. I need to finish welding it and figure out a way to more securely hold the radiator in there, but so far so good!

Another day, another day closer to this car's first speeding ticket in 40 years. Cleaning up the floor, removing interior (shockingly good original door panels!) and figuring out some plumbing for the intake.

This factory opening can work something like a cold air intake. I will fab up a surround for the air filter to shield it from the hot engine bay air. I think realistically this factory opening can feed the engine ok enough. Prefer not to cut, I don't like modifying these old Buicks![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)

I have looked at this AC link as this person has the new AC compressor working with the correct wiring. I am not far enough along to try this but I did bookmark the info so if you guys want to verify it works that would be great. Love the Buick! you do great work and it is well documented

Thanks guys! and thanks Kermit, that's some really great Gen V info there!
I fabbed up a passenger side air box replacement with a heater and AC line bulkhead. I made it out of 12 gauge- complete overkill but it makes for easy welding and no warping. Those huge factory air boxes sure are handy. I won't have to do any cutting and maybe just a little drilling. I plan on going the vintage air route.

The radiator bracket blends right in, you don't really see it. I used 3/8" weatherstrip from home depot on the radiator bracket on all the surfaces the radiator would otherwise touch.

Mounted my condenser and power steering cooler. I'm not sure if the PS cooler is necessary but the hydroboost may contribute to more heat. I was actually going to use that cooler for ATF in conjunction with the radiator ATF cooler. I have another one of these swaps in an F250 and it has only the ATF cooler in front of the radiator. Even when towing the ATF temp doesnt get very hot so this car should be perfectly fine with only the radiator cooler.

I'll order some plumbing for the drier and condenser now that I have measurements.

I bought a vintage air dummy test fit piece. these are really handy, they dont weigh much, theyre cheap and they let you mock up the system. I'll have to do a little bit of cutting on the firewall but I should be able to mock it up and make sure it clears the dash soon.

My Dad had one of these Specials like yours, 2 DrHdtp and all. Had a 264 CI engine and Dynaflow. Dad like to go so he traded it off in '62 for a new Olds with 4bbl 394 CI which really went. But he really missed the old Buick. He would love yours and your swap and mods if he was still alive and would appreciate your beautiful, detailed work. (And he would bug you to drive it!)
Thanks for the great pics showing your build and your commentary. I'll stay tuned.
