Degreeing my cam
Ready to install my cam and looking for feedback, suggestions and tips for degreeing it. Looking at kits to purchase I see some for "heads on" and "heads off"- seems like heads off would be easier?????? I also see a kit specifically for "Mopar and Oldsmobile" engines better than a "universal" kit???
Thanks!

Kit?
All you need is a degree wheel (larger is easier to use and more accurate), a piece of stiff wire to use as an indicating needle, and a dial indicator with a magnetic base.
It is definitely easier to do with the heads off (@&#% PIA to get TDC just right through the spark plug hole), but either way will work.
Just confirm TDC, set your pointer at zero, set up your dial indicator on the appropriate surface, and measure your lift at the specified degrees.

Agreed. I bought an inexpensive dial indicator kit from http://www.use-enco.com, a degree wheel, and then made a spark plug TDC tool out of an old spark plug and a long bolt. Total cost was probably under $60.

Depending on the kit, mounting the degree wheel to the crank can be a PITA because type C motors use evidently a 1/2" bolt or something.
Should have the flexplate installed to turn the crank with so that you don't disturb the degree wheel at all during the process.

Rather, you use a piston stop to stop the piston well short of TDC while turning the crank one direction, note the degree wheel reading, then turn the crank in the other direction until it stops, note the degree wheel reading, then zero the wheel halfway between the two readings.
I'm pretty sure Eric knows this.
