I wish that they would come out with a awesome cylinder head for the 318's for the street. Edelbrock has a cylinder head for the small bore small block chevy. This new high performance cylinder head is going to create a demand for it and a street 318 would do the same

318 bore isn't small it can handle valves larger than 2.02, It's smaller than a 360 but not by a huge amount especially after an overbore. If a 360 came with a 3.31 crank would of been a 333 cid engine 15 cid larger and a 340 7 cid larger than that. What would aluminum 318 head be ?
Basically copy of a Magnum or 1.88 J head ? Performance wise.

The 318 head is basically a 273 head and was designed for that which is a decent piece for a 273 has about the same cfm per cid ratio as a 340 why both are considered revvers.
A 340 head was designed for a relatively mild 340 275 hp only 22 cid more than a 318 and far closer than the 45 cid difference between 273 and 318.
