Just looking to confirm my compression ratio....
109 block, zero deck
Diamond .020 pistons (part #21401)
Champion GN 1 heads
Head Gasket ( can't find stat, standard gasket kit from Full Throttle, can't find listing)
Factory crank and rods.

Thanks
 
nowhere enough informatin to say what your static compression is. You need to know piston dish cc's, head cc's and head gasket cc's (and of course stroke length is factor as well)
 
Sounds like 8.9 - 9.1 to 1 assuming a few things. 46 cc heads, -29.5 cc piston dish, 3.8 cc head gasket, 0 deck.

google "compression Ratio Calculator"then put your information in and enter it.


Thanks
 
Help much appreciated.

I have all required info for calculating the CR, except victor reinz #3797 head gasket specs....I've googled it to death with zero luck.
Looking for Head Gasket Bore Diameter, and compressed thickness of the #3797.
