Internally or externally balanced flywheel?
I have to change my flywheel and cluth on my 70 Fastback. I wan't to confirm that this year had an externally balanced flywheel. How can I tell just by looking at it on the engine? Minehas 157 teeth. I want to buy the Ford Racing 157-tooth, external, 28.2in/oz. imbalance flywheel (part # M-6375-A302) from Summit. Also to go along with this I would get the Centerforce Dual Friction clutch (part # DF490030) from Summit again. Are these a good match? While I'm at it I will change the rear end for a Currie Enterprise centrepiece Trac-Lock with 3.50:1 gears.
Any comments would be appreciated.

RE: Internally or externally balanced flywheel?
That factory 351s were all externally balanced and 28oz should be the right one. That being said, many performance shops and performance engine builds move over to internally balanced cranks, flywheels, and balancers. My 383 stroker is internally balanced, but all my factory Windsors and Clevelands are externally balanced.
On another note. They are more expensive, but aluminum flywheels are MUCH lighter than steel ones! Also Fluidamper makes a great balancer.
