318: What Will It Make?

300 corrected should be doable.

For reference my 318 made 352hp on the dyno with 10.39:1, thumpr cam 227/241 @ .050 and 2.02 J heads with a bowl blend. performer RPM and 1-3/4 headers.

I've since went 254/254 solid cam and a bit more porting and it feels noticably faster with my best ET being 13.96 @ 98 in a 67 valiant (never raced before, bloody hot aussie summer day, running a little rich with a super restrictive twin 2" exhaust system, heavy 5 blade truck radiator fan. could use more stall etc and any other excuse you can think of)
