Sounds like WAY to much total timing. Check with your builder, set timing to spec, re-set idle and see what happens. If no good, go back to my first post and follow along! Please let us know what your initial timing ends up being.

I agree with Rick,way too much advance for your 418W.

If you have an MSD,it sounds like you have the blue advance bushing.It allows about 22*.The black cuts it down to about 18* cent..
Your stroker only needs 34*.

I have attached a link that shows what the diffferent bushing and springs do.
