Okay I lied. It's really a Midget 1500.
I have a stock cam, and I just want to make sure it is timed correctly.
What I have done so far:
I have aligned the marks on the cam and crank and installed the chain. I have used a dial indicator to find TDC. My dial indicator is now following the intake lifter for #1 cylinder. I have a degree wheel on my crank. What I am having a hard time understanding is how to read my degree wheel to determine if my cam is aligned properly.
Here are the numbers I have for my stock 1500 cam (from Paul Tegler's site).
Lobe centers 112°
Intake timeing 18°-58°
Seat duration 247°
.05" duration 205°
How do I translate my degree wheel readings so that they relate to these numbers.
Lemme throw this out: Starting from TDC before the intake stroke, I take a degree wheel reading when my tappet reaches .05" lift; I take another reading when it returns to .05" lift. I add these two readings then divede by 2, and if everything is aligned correctly, the sum should be 205°. Is that right.
If so, what numbers would I look for if I wanted to advance my cam timing by 2°.
Thanks.
