Have been running a Tomei 2.8 since 2005. Popped an oil pump in 2012 and put the crank back in.
There are for and against arguments for full counter and semi counter cranks.. In theory full counter are better, but, keep the revs sane and match everything up , does it matter?
You're after a "response" setup. If you need to rev more than 8500 rpm then you're doing it wrong.
