Oh dear God! 318 stroker

273 said
Cause a lot of people can't separate what the factory did performance wise and what's possible with any given engine. Look at 400 ford basically a 4 inch stroked 2bbl Cleveland but most think it has no potential, imagine if there was no 273 and 340 and 318 came with the 273 4bbl package then 340 trim. 318 would of been the legend.

To me I judge mainly by bore
3.625,3.91,4.00,4.04,4.125,4.1875,4.25,4.32,4.34

3.98 is midway, to me 318/340/360 bores are fairly close to each other even a 273 bore is good for at least 400 hp.

Same with the 400 sbc. Chevy guys like the 350, LOVE the 383 variant, and ignore the 400. Probably cause there was never a high performance version, just like 318, 400, mopars.
400 sbc can run hard with good parts, they don't even need to be great parts. Step one: pistons with some compression. Step two:decent heads. Step three, a decent cam. Step four: hang on tight.
The SAME formula works for 318s and 400s.
Potential of these and the Ford 400 is devalued, cause there was never a high performance version. It's a poor viewpoint.
