Re: pistons etc
My last engine used ACL race series pistons. My opinions on them isn't very good. The skirts collapsed causing what you'd call piston slap. My old engines bores showed some real ugly marks.
They lasted 25,000k's and I noted signs (smoke out the tailpipes) by 30,000k's they were gone. That engine spent most if it's life around 3000-4000rpm. Only went higher when I raced it. Cruise rpm for me (100kph) was 3350rpm.
