So, after some maths, I found out that my CR with the old pistons was about 11.1:1. TIDAK BAGUS!!! I mean I could run E85, but no, just no. I could have just run strait propane, but I like the versatility of gasoline. I mean when you are camping and you need to start a fire you just unplug the fuel line and BOOM instant fire. LOL
With the new pistons and eagle rods my CR should be about 9.7:1. Which IMPO is still kinda high for boost, but definitely doable with 93 octane.
I really wanted to be able to run like 87, but oh well.
Just gotta hone out the block and slap these buggers back in there.
