Chevrolet 350 (L48 / base Corvette spec) competitor (above)
So I only aimed for 200 hp, being led to believe it was an accurate number to go for based on this quote:
Though after rereading the same page now, it went on to mention “L82 (250 hp rated), 6.7 seconds”, so… yeah, that would suggest the factory quoted 300 hp was maybe quite accurate despite being in SAE gross, perhaps a fail on my part.

By extension, this engine is perhaps super underrated as well, though it did seem 270 hp would be about the limit I could get from this engine (by using High instead of Mid range intake and headers) without going crazy, so, I’m not sure what to make of that.
Also, check this thread for a 264 ci 151 hp engine meant to compete with the original 1955 Chevy small block: So, I think I went overboard making variants of these two engine families - #10 by Ray_V0lut10n
