It is the 241 @ .050", 484 lift hydraulic. And yes, this shop had about 5 different muscle cars that they were working on, plus mine. They have been around for a while and were even on Garage TV at one time. But they won't be seeing me anymore i can tell you that!
There are two versions of that cam...which one did you get?

I found it strange that all of the plugs in cylinders 1,3,5 and 7 were fouled and all of the plugs in cylinders 2,4,6 and 8 looked good. Whats going on there?
Take a good look at the intake sealing on the driver's side, especially between the valley pan and the head. Sounds like it's sucking in oil (and air) on all four of those intake ports, which would also explain the poor idle

Yeah, it sounds like your jacked up on one side of your intake.

Why are there so many stories like this from "performance shops"
do you personally know the people who work at or own this shop? Who told you to go to them?
as previously asked...what IS their experience working on old carb'd engines?
I can't believe a shop would tell you that you DON'T want to degree in a cam and then not do it after you asked them to. They probably told you what they did because they don't have anyone there that knows how to degree a cam.
Makes you wonder if they did the proper cam break in or not? 20 minutes at 2000 rpm. I would call them and ask, if they didn't, I would go do it yourself now before you let that engine idle anymore. you could have a wiped lobe in your future if you don't.
Where do you live? maybe you can find a member here who can stop by to help you out?

Degreeing the cam in with a little extra advance would have help some to then a nice 2800/3000 stall. You may need a little more idle advance yet around 30 so lighter dizzy advance springs may be in order. Yo can turn it up to 30 initial and that is 46 total to play with idle and in gear idle to see what it needs don't drive till you turn it back to 38 total!

I had the same cam in the 440 I had in my 69 Bee. That cam doesn’t make good power until 3200 RPM and above. I would go with a good 3200 to 3400 stall converter. I had a 2000 rpm stall in mine for a while and the car was a real dog until 32000 rpm then it was hold on. I put a 3400 stall in it and it became a beast off the line.

I had that cam in my old 383 Dart. It was a very mild 383 with 9.5 comp and 452 heads with mild porting I put the cam in at 104 installed centerline. The car had a Turbo Action tight 3000 converter and 3.91's. Eddy RPM intake and 750 DP. It ran very good with a best et of 12.31 @ 110. Good luck with yours and glad to hear you got it running good. Ron
yea get a good 3000 maybe talk to John Cope he sells PTC and they are good https://www.coperacingtrans.com/index.php?cPath=22&osCsid=a47b579864b6fe200757837f2a6ed2ad ultimate or dynamic but trust us don't save 200 and be sorry later! and if its a little off buy the stuff and degree the cam up a bit over the winter if it needs one last tweek! 104 i agree

So I figure stall converter of 3000-3400 then? Which brand should I go with? Are there specific converters for the Mopar 727 trans?
Call PTC and give them your engine/cam specs and they will set you up with the proper convertor for your combo.
