What happens if the timing chain is off a tooth?
You’ll either be way high or way low if your timing chain is off a tooth. You should be around 170 PSI with that combo. Distributor being off a tooth won’t make any difference, it’ll just cause the distributor to be pointing in a funny direction when the timing is set properly.
How many teeth does a cam gear have?
IMHO, it is a sorry way to compensate for the WRONG cam. A typical double roller timing chain set for a small block Chevy has 44 teeth on the cam gear and they cover 720* of crankshaft rotation (two rotations of the crank). Do the division and that’s about 16 crankshaft degrees per tooth.
What’s the best timing for a timing light?
Oddest thing is with the timing light my timing is 38* when it’s run’s it’s “Best” at IDLE! If i try to adjust it down to 16* or so it won’t run and it starts backfiring through the carb.
