I tried emailing them several times regarding this but I didn't get any reply thus i am posting here (I live in Singapore so its quite impossible to call them).
I am planning for an engine with MM pistons and conrods as well as crank (unless I can find the crank elsewhere). However, I am looking at a compression of 10:1 rather than 8.6:1, thus I am wondering if MM or any other companies offer a compression of 10:1 for the M47 crank configuration.
Thanks!
