Hello
re RPM limit of the 300 TEMPEST engine .
Ignorant to all the warnings, my engine revs upto 6000rpm
(@the built in tacho) and sounds well all the time .
Does anybody know the rev limits of the 1986 Mercruiuser 300 TEMPEST ..??? (Its not writen on the valve cover, sorry I read the threads first..)
Thanks for a short Info to

The tempest is a 4 bolt block, with a forged crank, so 6000 once in a while shouldn't kill it. If I were you, I'd get a prop that bring the rpm's down to 52-5300 @ WOT.

If it's a stock, 20 year old engine I'd be a little worried about the condition of the valvesprings and the valvetrain in general. Valve float could cause lots of damage. I'd keep it in the low 5000's.
