I here that you are supposed to use a flywheel in stead of a flexplate why. my rig has a flexplate it worke fine. another friend has BBC his works also. by not using one am I missing something.

i don't know why they put on flywheels. I replaced the 40lb monster on my olds with a flex plate and really picked up throttle response any one else have thoughts?

Well, with a small engine a flywheel will help it idle lower and smoother. But with a v-8(especially BB) you have enough rotating mass to keep the engine going smoothly. But a 1.8l Honda won't idle without one. Ditch the flywheel, don't need it.

Turbo, my guess is ,80% of the jetboats have a flexplate,go for it.

Just rebuilt 455 that was balanced with a flywheel. Could I use just any flexplate or would the flexplate have to be balanced? The crankshaft for this engine was balanced with harmonic Balancer and flywheel.

Travis ,your flexplate has to be balanced if your engine is internally balanced.Chev's are usually externally balanced with flywheels and counterweights behind the harmonic balancer.Fords are internally balanced up to around 1978-1980.
