Good for you! I've always said that I shouldn't be allowed to own a Deusenberg because I'd DRIVE it! (not like I have enough $$ to afford a Deusenberg hose clamp.....)

Today I installed a rubber D gasket on the doors. It went smoothly. It is cheap Chinese material so I don't have high expectations for it. I also found my big round red Studebaker emblem for the grill. I'll install that when i get a chance.

In driving it around today with the straight pipe you can hear the turbo from time to time. I think It sounds like a small cummins.

I'll hold the stock turbo with the clipped compressor for you. Given that we don't have a track for this year I may test the new turbo on the dyno then the drag strip and see if it works OK then send the current one off to you (it WAS you who was wanting the clipped turbo, wasn't it?). I'm pretty sure the big turbo will solve the "not enough air" issue I've been having.

Yes, cool! I am definitely interested in giving that clipped turbo a new home! It'd be awesome to be able to spin the donuts with it.

Today the CE is at the shop. They removed the 1" lowering block in back and are installing .598 diameter springs in place of the .573" springs upfront, in an effort to raise the car up a tad. We found the pinion seal leaks a bit on my craigs list ford 9" so they'll renew that too. And I found a blob of metal where the center of the drive shaft is rubbing a bit to be removed.

I have 50 miles on it now.

They also lubricated the ball joints and u joint. It steers very much nicer now. I can run it through the gears with some confidence now and drive it around corners with a little vigor, though the lack of side support in the dilapidated seat prevents any real enthusiastic driving.

Today I drove the Stude around. It was in the eighties so I turned on the AC. It blew cold air quickly but soon the belt was slipping so I'll have to get in there and tighten the belt. I found that a couple of places I asked my Indie to trim for more room for the engine to dance around have not been opened up. I noticed something hitting when I backed up today.

Fun driving it though! I always get to chat with some old fart about it.

Today I took it out. Went to the drugstore and the park with the GC and Children. I also took it out to a sort of bypass road which is divided. I took it up to 85 mph and held it there for a couple of miles. The temp got up to 200F. When I took it back down to more normal speeds the temp came down to bout 190. Cruising at 70 was very comfy without too much noise. When I get door panels, headliner and rugs in it it should be very quiet.

Excellent! Do you have any Water Wetter in it? I've found that to be helpful in a car that runs on the hot side. Or MXFrank can build you a slick radiator if it proves to be an "issue".

I think its likely the restricted grill openings of the 39. Once the speed is back to 70 it comes right down. 200 under a load is not unusual I don't think. OTOH the rad is a stock mb one from my parts car so it could be on its last legs as far as that goes!

La Salle grill? Is there room for a scoop to direct air from under the bumper to the radiator?

I could add a scoop but really I don't need to go 85 mph. 70 will probably be plenty.

I didn't take them all at the same time.

(silly sixto).

You actually look to have more grill area that our thirty nine Buick. Ours is on the original rad or a long ago original type replacement. In any event the cooling demand with the much more powerful 327 under the hood is seemingly easy met.

Yet there is a problem. The underhood temperatures are far higher than I like created by a lack of enough air flow through the engine compartment. The radiator would see even more increased efficiency if I had some louvers punched into the inner fenders. When I open one side of the hood after a good run there is just too much retained hot air in there. Indicating the lack of enough air flow through the engine compartment.

I have also always thought at high speed engine cooling is more influenced by the natural air flow through the radiator more than fan effect. So any change occurring in the engine compartment should not reduce air flow volume ability. It actually increases the air pressure enabling better air flow through the radiator and engine compartment with a well fitting shroud.

I think the 327 engine in place of the straight eight in our car does exactly that. Impairs the flow through and the engine compartment gets pretty hot as a result. Not hot enough to damage the paint on the hood but it should be lower.

Thanks for the comments Barry. Of course in my car I can remove the side panels of the hood and run that way if I like. I imagine you can too if you want. There also was a reason the hot rodders used to cut louvers everywhere. (Get that heat out!)

Only as a test if you seem to have added too much obstruction to the airflow. The original engine in your vehicle probably was a lot smaller physically. Plus I did not think It was as likely to be the problem with a five cylinder 300d in line engine change for a smaller six cylinder in line change. Unless the obstructing mass of the 300d was a lot larger.

The designs of the time did narrow up that compartment a lot on many brands. I really did not know to post that information or not. The same applied to your too low front end. I assumed your front end kit did not have the dropped spindals. Plus you knew that. I am well aware you know a lot.
