Can anyone tell me if a Stock DeSoto 291 4bl intake carburetor mounting pad is level with the engine, or tilted forward...tilted forward to compensate for the engine tilting backward. It's tough, trying to figure stuff out, being 1,200 miles away from the engine. Thanks, in advance, for any info...
As I don't ever remember seeing a production rear wheel drive car with the back of the engine higher than the front I would have to say set it level with the back of the engine lower than the front. Someone can probably post a side view drawing of an early hemi showing that. A couple of photos here http://www.aaronscustomrestorations.com/55desoto.html The engine is a two barrel but from looking at the photos I think You can see how the engine sets as compared to the carb mount or top in this case.
I couldn't tell you off the top of my head, but if you haven't gotten a straight answer from anyone by this evening I'll check the intake on my '55 when I get home from work and let you know. But I'm thinking that the carb is level with the engine.
I had a chance to check out my intake- while I couldn't really measure it without taking the air cleaner off, the carb does appear to slope forward.
EARLYHEMIBILL - Yup. I'm home now, and checked it. the intake has a tilt and yes, I'm using it for a blower base...
Sweet! I remembr back about 1970 an article in Hot Rod. A guy milled off an intake until flush with the block and put a blower plate on it. The blower was junk. He then took the rotors out of the blower and placed the carb inside. The pulley was still operational. Didn't do anything for the power, but still p***ed emissions. Hope for a photo of your setup.

EARLYHEMIBILL - I DON'T want to ruin the 291 4bl intake...they're not that common. What I plan on doing is the way it was done years ago. I have a 3/4" aluminum plate cut to fit JUST inside the bottom of a Dyers cast blower intake top half. That way I can set the plate on top of the intake, slip the blower intake onto that, then move the whole thing front to back/side to side up and down until it's exactly where it needs to be, then mark everything...including the holes to match up with the studs and throttle bore openings on the intake. Bore the necessary holes, and weld up the manifold top to the base plate. Then the whole thing bolts to the original carburetor studs, inside the finished manifold. I don't like the looks OR the price of a weld up intake, and there aren't any cast blower intakes for a DeSoto. I plan on taking pictures, every step of the way...
I HAVE A 291 W A 4BBL AS WELL AND WANT TO USE A BLOWER ANY ADVICE ON HOW YOU DO IT WOULD BE GREAT. i'M STILL IN THE TEARDOWN PHASE BUT TRYING TO PLAN AHEAD
Stude, i milled an intake for a neighbor, and ran into a heat crossover before i had it flat As for desoto, i think they are pretty close to flat atleast close enough
Wish your intake was here. I'd put an auminum plate on the mill and cut it at an angle for ya. I have a 341 4-bbl intake but don't know if the angles would be the same. I have a 6-71 and am designing a blower intake for it. Will be cast here at home. I did recieve some autocad drawings from someone awhile back. It was a set of 3-D drawing from a company that was going to build a blower inteke. They decided against it I reckon. Besides, it had no provisions for coolant so it would have just been a 1/4 mile deal anyway. Bill
EARLYHEMIBILL - To save on the expense, you might try what I'm doing. The largest expense is the $195 for the blower manifold top from Dyers...quick and dirty....
