I just wanted to know the lowest compression you could have and still start. I have fuel and spark but it won't kick over. Anybody recently do a compression test? Numbers would be appreciated! Thanks Again!

Old motor:

130 120 110 60

Still ran a 16.0 at the track..hahaha.

Thats shitty! ROFL

In terms of simply starting, when I bought my first DSM it had 120, 120, 80, 0, and it started fine, idled perfectly, and drove fine, slow as all hell, but drove fine.
 
Well i did the test i got 0 0 0 and um 0. Took the valve cover off and guess what i found? My Intake rockers from one end to the other!
 
My old laser had 93 91 90 92 ...It still ran but smoked like a freight train. LOL!
 
You weren't kidding all 16!!!!!!!! :mad:

Intake Rockers were spread across the head from one side to the other!
 
I guess i already said that! But im upgrading to 3g lifters, super flo valves, cams ect. Just a little sooner than I wanted too!
 
When I melted my hg, compression was 95,90,85,80 and it WOULD start but only after hooking up jumper cables and cranking the ignition for close to 5 minutes. Car ran like shit though, would barely even spool my turbo.
