261 FLYWHEEL REAPPLICATION - 01/26/12 01:28 AM
I have a 261 truck engine and flywheel that had an 11 inch clutch mounted on it. I.m putting a car bell hsg on the engine and don.t think an 11" clutch will fit in. Question, can I drill new mounting holes in the flywheel to accomodate a 9" clutch. Concerns - NC machine work should be able to locate the new holes near perfectly about centerline of flywheel??? The new holes will be in the web (thinner part of the flywheel
)but the thread engagement depth looks about the same as the 11" holes because they are countersunk, the 9" holes will have no countersink. Spin balancing - is the flywheel balanced with the engine or clutch attached, or is it needed as this engine is not hot rod bound. Thanks in advance for your response.
