I finally found the problem was timming was comming in to slow. After getting my curve right I went right to low 1.6x 60's with no other changes

Not saying this is your issue but might be something you want to look in to.

You are right on on the distributor.
I did not bother with carb tuning because the curve is not were it needs to be.

Very happy for sure.

This is the first time I have read your thread and those are some nice numbers. I recently built my 350 for my w31 and got 400HP. Here is a link to the engine idling on the dyno. http://www.youtube.com/watch?v=B525a...ature=youtu.be

I am in agreement with Mark on the camshaft that a wider lobe seperation may help. Again, I like your build!
