I'd ask that machine shop why the 1970 L46 350/350 HP Corvette engine needed 11 : 1, 2.02"/1.60" 186# double hump heads, 765 cfm carb, and a .450/.460 lift cam with 224/224 duration cam.

Here's a great article dyno testing the 350 HP L79 327 and L46 350 engines.

The "Its easy to get 1 HP per cid" thing gets thrown around a lot these days, but it takes more than most people thinks it does with 30+ year old stock small valve heads. Its much easier with ported or modern heads. Its even easier with LSX engines, again, mainly because of the airflow of the heads.
