1971 Satellite 383 block, .030" over, stock stroke Forged pistons .021" in the hole Stock 906 heads, new springs with dampners (Pioneer rv891x) 8.80:1 measured compression 727 2.76.1 or 3.23:1 rear end DP4B dual plane intake 650 Eddy carb HP exhaust manifolds power brakes air conditioning
This will be a 100% street car and will never see anything over 4000 rpm. I need vacuum for brakes and vacuum controlled dash/heater box. I want to run a/c and have it get decent mpg (I'm guessing 16-17???).
What cam to use?

Probably about the easiest cam question there is. You could go with a stock cam, no problem.
Check out crane grind # H-260-2 that's actually a little weaker than stock, and will have a tremendous bottom end. 112 LSA so it'll have a good idle and lots of vacuum.
Personally I'd go with a modern/stock equivalent grind, so you could at least wind up and be satisfied if you wanted to.
Seriously, any stock replacement came or the so-called RV cams will work great for what you want.

6401 Summit Cam is an amazing grind perfect for your application--383's need lots less cam than others that unit will idle well still sound Good, Melt tires off idle and pull like a train to about 5000 what more do ya want? And it is CHEAP!!!!!!!!!! I have used that cam in over 30 big mopars--it rocks for street applications with low to med compression like yours--trust me -it is an amazing camshaft 224 234 460?/ 488 exh lift I would install it around 102-103 with gears you plan it is PERFECT!

I have used it with smogger shortblocks all the way to true 10:1 Yea more compression runs better but his application will work great with that cam advanced a little like I mentioned---It will run fine with less CR than they advertise--they gotta put something in that blank--the 6401 will sound great yet is not too big to kill it --it runs like a much smaller cam IMO I usually install it at about 105 in a higher compression and around 102 in lower with fantasic results--best street cam ever for CHEAP

I looked at that cam and they are recommending a minimum CR of 9.5:1. What ratios have you used this with, specifically what do you mean by "low to med compression"?
I am using the 6401 in my 440, and I agree. It is an awesome cam in my relatively stock build, but I have 9.35:1 static compression. I went around and around with this also because it was less than 9.5:1. They determined that a point and a half wasn't enough to worry about. 8.8:1 may be though. I would try to bump up the compression or pick a stock cam as mentioned. It will definitely run good with the 6401, but you may be leaving some HP/TQ on the table compared to others.

Not that I know anything, but Summit 6401 seems like a big cam for low compression 383 with 2.73. No mention of transmission.
68 Roadrunner. 383 4-spd. Beat up.

http://www.summitracing.com/parts/LUN-60300LK/http://www.summitracing.com/parts/LUN-60301I'd go with the voodoo 60300 or 60301..... apples and fruit loops, but I had a similar duration hydraulic roller in a 9:1 magnum headed 318, pulled real good from idle to about 5500 RPM, plenty of vacuum for brakes and A/C
