Is there a tool that will check cubic inch displacement by using the spark plug hole, without removing the heads to measure the bore & stroke?

If so, where is the best place for me to find one of these tools ?
What do you call it ?

My block is a 401 but I found some interesting marks when cleaning the engine and I'd like to know if it has been de-stroked to 304, etc..

Or, is the only way by removing the head to measure bore and stroke ?

Thanks

Mike

It's normally referred to as a swept volume test and is a common test in motorsports to prevent cheating.

This is a fairly expensive test rig, probably cheaper options out there:

You could probably make something fairly cheaply to do the job.
