So I saw a 95 240 cluster and noticed the rpm redline stops at 6500, I have a 91 and it stops at 6900. I was wondering if I was seeing things or if this is all true, and why they would do this? I thought it was the same engine.

Drifferent cam durations. KA’s are usless past 5600rpms anyways. I used to run 2 248 duration cams, a port match and polish in my ka no real big differance.
