I had the same issues with a 440 I slammed together. Turned out I installed the cam 180 out!! Check into it. I did exactly what you are talking about.



Just how do you manage to install the cam 180 out? You index the cam to the crank, and the distributor to the cam and TDC. Draw a line through the center of the crank and cam, and you line the dots (arrows, whatever) on that line. At this point it doesen't matter if the dot on the cam is at the top or bottom, as long as it's on the line. Turn the crank one full turn, put the crank dot on the line, and the cam will be on the line, too - again, either at the top or bottom, the opposite of what it was. It's either right both ways, or wrong both ways. Then you line up the crank on TDC, both #1 valves closed, and drop the dist (pump drive gear on a Mopar) with the rotor aimed at #1 on the cap, and the firing order to match the cam. You can have the dist 180 off, but not the CAM, and it won't run with the dist 180 off.


Good Morning everyone! I'm sure the cam is not 180 deg out. It would not run at all. I'm thinking it a tooth or 3 off from where I did the degree procedure. I've went over this build in my mind 100 times, that was the only part I wasn't 100% comfortable with. I don't think it has anything to do with the MSD, because it ran the same with the Mopar stuff. The box is a MSD Digital 6AL with rev limiter, MSD Pro Billet dist, Blaster SS coil. Wired up exactly per instructions.
The cam is hydraulic and is a 4 speed. I forgot that info!
I'm going to double check (again) all the simple stuff, then prob pull the cover. I've even thought of a solid cam. Any thought about the Mopar Purple # P4120659 528lift, 284 duration. Or, any other thoughts. Thanks again!! Jeff
