Is it the sticker on the air cleaner????

What constitutes an engine to be "Hi Performance" ? ? ?

• Is it a horsepower rating??
• Is it because it has a performance piece added to the typical run of the mill ??
• Or is it the label on the air cleaner ???

If it's HP rating, then today's run of the mill 4 banger in a honda is just as much of a hi performance is many labeled "HP" engines from back in the day. And the 3.6 PentaStar is more of a HP engine than the legend 340. The 318 2bbl is a factory HP engine because it boast more horsepower than some of the "HP" engines.

If it's a performance piece, then the super six (225 with a 2bbl) is a HP engine. Yeah, floor that and feel the excitement!

I think it's sold to us by a sticker on the air cleaner. :) That makes the 283 2bbl "turbo fire" an HP engine. I've driven them, and I beg to differ.
