The intake runner was to long with the spacers I did not shorten the runner of a 420 at all.

We just added Plenum Volume to a "420" And positioned carb boosters over each pair of runners better.

I think it will accelerate better but.... ever know🙃 Untill you try things.

Testing I have done shows this should be good improvement 👍🏻
