This sounds familiar...I had a similar problem a couple of years ago and it turned out that my timing chain had jumped during break-in. If you start losing teeth on your ring gear, this is your problem.

Double check the dial on your digital box and then make sure it's set to not pull out the 20* and see how it starts for ya! That may atleast help that issue.

Hey everyone! Guy's I really appreciate all the help on this one. I have double/triple check'd TDC, where the rotor is at #1, plug wires are on the correct plugs, etc. I just did a compression test. Not good IMO. All plugs out, carb WOT, 150-160psi...I would think should be over 200 with my set-up. I'm thinking timing gears are not correct. I used the double roller timing set-up with the multiple crank way. I thought I installed it at 2deg advanced, but now, I'm almost positive I goofed up somewhere. I just looked at the MSD wires again. At the plug at the MSD box, the tach wire is definitely grey or tan. I'm color blind on light colors. Keith, you are a gentleman and a scholar! I really appreciate the offer and would make it worth your while! If I can't figure this out by checking the timing / degreeing, I'll take you up on the offer! Again, thanks a bunch!! Jeff

Solid Core spark plug wires cannot be used with an MSD Ignition.

First you compression is about 10.25 so 150 to 160 is not that bad with a 246 deg cam. did you check you cam degree again after picking the +2 deg keyway? always check check recheck next 57s are way way too cold for that engine go with 61's or even 63's just go to your local parts store and grab a set of RC12YC and put in to try! you are sure your firing order is correct?? seen a guy swap 6 and 8 and is power was down 40% and they are so far appart in the firing order not mush ill effects just two cold holes! and of course 5 and 7 are easy to mix up! :-) On second thought you should be around 180 so maybe you cam is installed retarded??

A temp. gun will tell you if you have a weak cylinder. If you have tried everything else and nothing has worked,it may be time to try and set your dist drive gear like it calls for. I had the same problem and that was the fix for me. Some times its the simple things that get you. I know everyone thinks I wrong but is it not a least worth a try?

Hello Everyone! Pulled front of engine apart this afternoon. I was hoping to find I had gears off. Well, according to my machine shop / engine builder, it is the way it should. I've attached a pix of the gears. We called Comp. The cam is a custom grind. They said on 7 1/2 CL. I kept comming up with about 8 1/2 so I advanced it 2 deg. You can see this on the gears. Now I'm kind of back to square one! We are gonna double ck this again tomorrow. I did double ck at TDC and I'm pointing at #1 on the dist. Firing order is correct. Checked 3 times with another set of eyes! I just can't see it being ignition related, because it ran the same with the Mopar ignition in it. Just very lazy, no power to get out of it's own way. Anyone ever heard of a cam doing this? Crank key wrong? I'm lost (again)! Take care, Jeff
Not sure who said it, too lazy to look, but now that you checked the cam, I would check lifter preload, valve adjustment. I would think even if only one carb was working it would still run okay. Did you check the gas like was suggested? I'm waiting to see what you find, interesting problem, hope I don't have the same one shortly.

Really stupid questio, but is it possible the plugs could have become gas fouled upon your initial break-in? I had a crate motor that behaved exactly this way, finding out later that I had gas fouled the plugs on a fresh small block crate motor. Just a thought.
