your going to need new pistons. Will be easier with a 95cc head
If your compression is a true 13.7 to 1, then installing a 6.7 rod will get the compression to 10.8 to 1 using your existing pistons with a 1.25 compression height.So Im looking into building a turbo bbf.. currently i have a 545 bbf.. 4.5 stroke 6.8 rods.. .30 over flat top pistons.. 13.7 compression ratio through a .39 gaskets
Im not sure about my options for lowering the compression though.. could I just switch to a 6.7 rod and get a lower compression.. I know the 6.7 would lower it but how much is the question.
I want the motor to be 9.0-1.. I can deal with anything for 8.5-10.0 though.. Thanks for any help
