I've got my engine on a stand and I'd like to try and figure out how much displacement I've got. I just replaced all my pushrod tube seals and did a valve adjustment, so I don't want to remove the heads. The engine came out of a '71 and was running 40IDF's when I bought it. The car makes a lot more power than a stock '71 injected engine, so I'm curiousif it's been fitted with larger cylinders. Might just be the carbs I'm feeling...
One idea I've got is to set a piston at BDC on the intake stroke and then CC the chamber through the spark plug hole, carefully stopping the liquid when I reach the bottom of the plug hole, then measure the amount. Problem is, the intake valve will still be slightly open at BDC, since most cams have at least one valve open at BDC. Got any ideas? |
