Im wondering what compression I have..Im suppose to have 10.1 ...how can I tell?

does it have to do with the pistons and heads? My pistons are Keith Black .30over flat tops.

I dont have a compression tester thingy...and I dont feel like buying one.

I just need to know for sure what I have so when I get a cam and heads I know what I have..

can someone help me out?

 

Here is how you calculate it:

AH!...isnt there an easier way?...LOL

 

Not really....unless you buy the pistons with the kit and it tells you what cc heads to run to get a desired compression.

That's the true way to get your true compression instead of just an estimation from the piston and head cc. B/c gasket thicken, block decking, etc all plays a role in compression.

 

well crap!..then Im screwed.......I kinda wanna know for sure what I have...cause if I order a cam and tell them that I have 10.1 and dont then the cam will be wrong....so now I dont know what to do...Im suppose to have 10.1 according to the guy I got it from..but for some reason I dont think so.

 

Well. you can always get a guess by getting the pistion part number(mine was stamped on the top of it) and look it up and see what you come up with.
