My low-dollar 318 ran 14.9's with 2.76's at about 95 mph. Low compression and short block never disassembled. Just a cheapie summit brand cam, stock 318 smog heads that I dremeled, and a 4bbl. I'd say that's a sad day for the "high compression, larger cubes, better heads hot rod engines"... when a X-head 340 and 3.55's can't beat the ET or MPH of a low compression 2.76 geared 318. That's why it seems they are on the slow side.
