71 340 Compression Test

Thanks guys for the info. I did hear a light tap in the engine. Sounded like it was coming from timing cover. It was high pitch kinda like a lifter tap but not as loud. I was was planning on replacing-timing chain and gears with cam/lifter upgrade. I had a 280H Comp in a 73 Nova 350 and got about 200k mi out of the engine.
It also ran about 205 psi on compression with 10.5:1 TRW flats in it. This 71 was supposed to be 10.25:1 so I was expecting more psi. One of you guys are right about the pump gas. Couldnt shut off the old Nova without putting in 4th gear and letting out clutch. Had to run at least 93 octane.
Thanks again for the advice I do appreciate it. Always helps to ask if you're unsure about it.
