On the Dyno at Hendrens we played with some spacers. HVH 2" four hole tapered Super Sucker, 1" 2 hole Super Sucker, open spacer and a standard/cheap standard 4 hole spacer. The cheap, 4 hole spacer made the most power.

What about spacer on a 604? I have a moroso 1 in. plastic spacer or a 1 in. super sucker that I barrowed.

Plastic spacers work well on drag cars but the heat of an oval track engine cause them to leak. The Super Sucker is a better choice for the 604 anyway.
