383, short stroke, low compression, 3.23, low stall ALL equates to a sloooooooooow air/fuel response in the intake tract. Notta good idea.
An old DP4B aluminum intake is whatchya need.
I'd use the stock iron piece until you sell/trade the Torquer for a aluminum dual-plane.

My 383 had the stock Iron 4bbl intake, then I switched to a Performer, then to a torker. Still run the torker on my 451. I never noticed any power loss or gain for that matter by switching intakes. Not on that motor. It was also a very low compression motor with the psi killing MP474 cam. Cranking psi was only 96-98. Still made 13.72 1/4 mile times with the 3.91's , 3000 stall and headers.
I'd just advance the Summit cam, Run the Torker and put in the 3.91's if you want to beat on it. Without tearing into the thing and getting the compression up with some quench, you'll most likely just be stirring the poop soup.
My 383 (attached picture) was a big mismatch of whatever I could find for cheap, the 4780 holley 800 probably was way too much but it ran fastest with that carb too. Intakes and carbs on big blocks are a one or two beer job so for now I'd just run what ya have.

my real preference would be the Crower 271HDP 224/234, .486/.496 but have it custom ground for a 108 centerline (std is 112) and put it in your motor +3 at 105, on paper it's similar specs to the Summit, but it's a much better mopar lobe and it makes a mild 383 run like a scalded dog
So you would recommend the the Crower custom ground at 108 LSA even for an automatic? I was under the impression that since he was running an automatic that he'd be better off with the wider powerband of the standard 112 LSA cam? What kind of difference in vacuum would you expect between the 112 and 108 versions of this cam?

the Crower 271HDP cut on 108 is to me the hot ticket to really wake up a mild street 383, it's not a ton of duration so overlap is not an issue even with an automatic. PM member Mopork, he took my recommendation of this exact cam and dropped it in his uber-sweet 383 71 coronet cop car, he's told me on more than one occassion he's VERY pleased with how that cam runs.

I don't recall if the vam was installed advanced or not? The engine is at my parents house, maybe I'll go get it and check the installed CL. I did not want to give the wrong impression, the cam made power, but my stock converter and 3.23:1 gears made it slow off the line although that may have been partly the way the engine was tuned. I was using the stock advance curve in the Mopar distrubitor. It seemed to have good power from 2,500-5,000 RPM. I later did replace the rear gears with 3.91:1 ratio and used a single plane intake, but then I accidently over reved the engine. Went from third to first and had the dumb shift kit option that lets you do first gear at any speed. I think it may have hit 8,000 RPM? Result was a few bent intake valves.

Since this subject has been raised... I took an intake in on trade for some parts, I thought at first glance that it was a 383 Torker intake but it actually says...Edelbrock TM6 ...on it.. Is this the same as a Torker or???? Thanks
Different intake. Runners of the TM6 are larger than the Torker but at first glance they look very sinilar. Click on the link someone gave above from HRM for more info. Here's some pics from the archive: http://www.moparts.org/Tech/Archive/bb/14.html
