Hi guys, I just put together my motor and have not checked compression yet and was wondering what  you guys think it should be around,,its a 23hp vanny with 16hp crank,arc long rods,flat top pistons,new rings,cheetha cam,double valve springs,billet retainers,ported polished heads,stainless steel oversize valves,billet flywheel, 2bbl carb,i wont be able to check till next week and  was just looking for what I should expect

You will have to get the rings to seat by running it for a while before you can get a real accurate  compression test done with a gauage.   To figure compression ratio you will just have to know the cc of your heads and do some math from there to figure out what kind of fuel to run.
