Engine combo advice

I would not use a comp ratio so high. IMO, it would be insane. The closest I would get to a high compression mill would be 10-1 with the Hyper slugs from Speed Pro, the 116's or KB's.

Your on the right track.

Sorry A/J. While you can science out and reason your thoughts with a good argument, it is not needed to go there. Custom fitted slugs to iron heads is overkill. It ignores possible trips to lower land levels. The limit of the states octane and driving the cost will make the car difficult to fuel.

The build is for......

We are building it to be easy to drive for the wife and my almost 16 year old son.

Considering it is his first engine build with a MoPar buddy at his side, IMO he need not push the engine build. He needs to just get a good combo together. Not a ton of science. In this effort the K.I.S.S. method will work excellent on many fronts and for the overall package and target.
