Stock 4AGZE pistons in 7A block will give you 10.8 CR (Edo got 11.06 cuz of the Bigger bore), so then using 1.5 mm head gasked you will get the CR between 9.5-9.6 and using 2mm head gasket will get you at 9-9.1 CR.
you have three options on aftermarket rods ARGO, PUATER, OR CUSTOM 700+ at min

if your keeping the 7a block the rods need to be 132.5
the 4afe are only 121.9 too short

also you need to specify those numbers like i did stroke /rod length

just saying .748" 1.693" 4.800" .856" well confuse people

and last i know you updated your front page but you might want to include links to where you got your numbers like i did it will back up your findings and be more creditable

and say doggy nik and edo contributed to the findings

give credit were its do
