There probably is, I just mean by the average guy's perspective, they would need to be more common, for that to be the common view. I bet a decade or so ago 500 hp would be considered dicey. I remember when everyone worried strokers would wear the bores out under 10k.

LOL! I remember that!

IDK, going back to the 70’s, 500hp from a small block wasn’t really done or at least publicly announced. The only head back in the day was the W2. Very pricey and an annoying few items a lot of people didn’t like. Dedicated intake, exhaust header patterns, offset valve train, all pricey!

When the Edelbrock head came out and a few had a nicely ported set up top, those were good times for a lot of guys that didn’t know how to port heads or afford them to be done up.
