Safe RPM Limits On 350sbc

Not Sure Of Safe Running RPMs On 350sbc - About 370 To 380 hp - Will Push 26' Scarab About 55 To 60 mph At Just Over 5000 RPM ???

When the rods flyout of the side of the block it's too high!

Would need more details on the engine. 2-bolt, cast crank will run in the low 5000 range OK, on the other end, a race prepped motor will run in the high 6000 range.

so anything up to 9380 RPM should be good.. anything above that.. well it will buff out.!!!

3" stroke will rev lots higher than 3.5". I suspect a stock Merc 260 would buzz up to 9300... once.
