Maximum rpm for SB

OK. I figured it was good for 5500 with an occasional 6000 burst for awhile.

I just remember my old 289 that I was always dealing with the small rod bolts and then the rail rockers that liked to pull studs.

That is one of my reasons for liking Mopar, shaft mounted rockers, 3/8" rod bolts etc. It is a far superior design.

Thank you guys, ROB
