I found this on Coast High Performance website. It is a dyno chart of a CHP 306 with hydrualic cam. 320 lb-ft tq at 3000 rpm is appealing. Peak tq is close to 400 lbs ft and 460 hp. 6200 rpm looks to be the limit as power falls off. Nothing wrong with these numbers for a 2300 lbs car.
347's, as I understand, won't last as long as a 306/331, because they use
oil. Okay, what if a 347 can be built that doesn't use
oil? Does this mean they will last as long as a 306/331?
