318 Build Up

I have been collecting parts for a Magnum head motor for some time now. I have 2 sets of heads, lifters,pushrods, springs,retainers,keepers the
Air Gap and the cam. I knew I was getting the engine a long time ago but didn't know what it was inside until I took it apart. Knowing what I know now I would have stripped the Lean Burn stuff off, stuffed in a new cam bolted on a nice intake/carb and ran with it. I haven't been able to find any info about
these newer 318's. Everybody seems to write about the mid 60's-mid 70's 318's. toolmanmike
