Compression checking

Howdy again. Next on the agenda is to check my compression, so I'm going to do a compression check for giggles. . .well mostly to see if I'm on the verge of blowing my engine apart before I get the vortech installed. Has anyone done it themselves? Since the coil packs are so far from the spark plugs, I assume you have to use some sort of long neck gauge? Anyone recommend any products in particular? Thanks in advance!

1) Good idea.
2) Yes or an extension
3) Most would work. I have one with a flex rubber hose with a steel extension. Analog type guage. Basicly one that's been in use for decades probably.

I suppose finding one with the extension built in would be best.

Napa has a ton of them, so I'll check to see if they have one with a built in extension. Thx Jeff!

Also read the manual for the proper procedure. ie.. TB open or closed, cranking time etc.. cold or warm.

You might want to make a note on how long the extension needs to be. If it's too short, UBscrewed. If it's too long, then it might hit stuff in the engine bay
