Re: Hidden HORSEPOWER in Side Gapping your Spark Plugs?

Beaver another reason to do this is also it helps deter detonation from the ground strap being to hot as well. Flipping the air cleaner base in the stock aircleaner does work. Especially so with a high flow filter. Indexing the plugs helps at higher rpm as well.

All these tricks are small on engines with a lot of power tapped out and many mods and improvements to make more power efficiently.

For you a stock 454 isn't going to see anything.

Try the big three. Intake, exhaust, cam. In that order. Don't want to tear down for a cam? Higher lift roller rockers can essential make your stock cam seem bigger. That's 10-15 hp guaranteed.

Do all these things and I will assure 75+hp gain
