Hi

Wondering if anyone with engine building experience can help me out or direct me a formula that will assist me.

I have a 9 port head which has been CC'd at 47.5

I currently run a 179 (192) without any trouble, however am looking at building a new motor.

I need to see if its possible to run this on a 202 block without compression being too high.

Can anyone help me with piston choice - will the dished ACL pistons availble drop the compression enough?

I don't want to run more than around 10:1 - I will be running 98 RON fuel.

Please - just responses if you have experience in this.

Regards
Dave
