Rapid Robert has it.

All I do is pull the valve cover and rotate number 1 cylinder to overlap, which is 180* after firing and look at the rockers for that cylinder.

If both rockers are off the seat the same amount, the cam is in straight up.

If the exhaust rocker is off the seat more the cam is retarded.

If the intake rocker is off the seat more the cam is advanced.

This doesn't tell you how far off you are but your cam should be in advanced a bit and straight up at the very worst.

That's the first thing I'd check.


This is why you never ever NEVER EVER install a cam dot to dot. The cam MUST be degreed in, especially with the advent of all these multi keyed crank gears and the directions that come with them can be confusing.

Degree the cam and none of that matters.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
