when installing the flywheel, does the position of the external balance on the flywheel matter relative to engine position? can't seem to find any information about this anywhere so i'm thinking 'no' but i just wanted to make sure. don't feel like pulling the engine again :)

No, the flywheel bolts holes are drilled in such a manner as to allow the flywheel to line up only one way. You'll see it as you try to bolt it up.

I don't think you can put it on wrong. If you look at the bolt pattern, there is a little difference in the spacing of the bolt holes. I think it can only go on one way. But, make sure to use some teflon based thread sealer or you could get an oil leak later on.

My 351w crank holes are blind, so I didn't need teflon tap or thread sealer.

Also, I didn't have dowel pins, just bolt it up.

Good luck, Go Fast

Also make sure you have the correct weight flywheel. Ask me how I know..

Yep, check the weight. The dowel pins are for the flywheel to clutch housing assembly. The 351 crank flywheel holes are blind. No sealer needed. Most builders use star washers for the flywheel bolts. Put the block plate on before the flywheel.

So the 351W flywheel bolts don't need the thread sealer? I guess mine definately won't leak from there!

Thread sealer is not required on a 351, but loctite is very helpful.
