Well Andy?

Would it be possible to tec my old motor for stock components without removing the oil pan, side cover and valve cover.

We can check for cylinder bore for oversize very quickly with the "Swing-blade Go-no-Go Gauge", the transmission for altered gears, non stock pistons, non stock valves with the bore scope and even valve lift without pulling anything off the motor or draining any fluid. A ten minute tec at most. We can check the head thickness also, but with the visual of the internal relation of valve to piston clearances with my cut away head one would consider that to be a non starter. To build any significant compression the piston crown has to be raised. This is a very easy check with just the bore scope

A picture is worth a 1000 hits on IOW.

If we are serious about stock motors internals, we could just give the racer the choice of removing the side covers, oil pan and valve cover or they could install a couple of Honest Dads......" Honest to God"..... inspection plug and cam lift checker.

The valve lift checker requires the valve cover to be removed one time to install it. Volumetric efficiency is key on these motor. The cut away demonstrates that unlike old school push rod motors we can't change camshaft duration without valve to piston interference. The only way to make the cam more efficient is more lift and or bigger valves which require special pistons. If the lift is stock the cam is probably stock. I bought a factory race cam once. Best I can figure it was a stock cam that failed inspection. Same lift and they said a few more degrees duration, that I never could find even by making a cam profile graph of both stock and factory race cam.

The inspection plug could be installed on the motor with the aide of a vacuum cleaner adapter and perhaps applying about 5 psi positive air pres to the crankcase during the drilling and tapping process to cause ejection of the aluminum chips. If an aluminum chip does get into the oil it would not damage the oil pump and the filter would stop it from going any further. Has anyone ever cut an oil filter in two, that is an education in itself. How did that stuff get in there? Through the oil pump of course!

The transmission inspection plug is already there on most of the newer motors, it is called the speedometer sensor.

Nothing to fear but an old racers idea of KISS.
