I think this is on topic.
300 hp is 2X the factory rating of the ford 300. It used a mellings tq cam (mild as it gets as far as aftermarket cams go) 9.5:1 comp ratio (pump gas friendly), idles like a stocker, got 17mpg in a truck (daily driver), there is no reason why this combination wouldnt be considered street friendly, dyno'd 300hp and right at 400tq at the crank....why couldnt a 292 accomplish the same thing?
500 hp street friendly, naturally aspirated, modern day small block, isnt out of the realm of possibility anymore. [/quote]
