273 Performance build possibilities.

I have followed a few hot rod 273 build threads here on the site and I have yet seen one get finished, ran on a dyno, or at the drag strip to measure horsepower. To the OP, build what you want , how you want but remember, it's only a 273.
waiting for it to warm up here in Wisconsin . then I will finish my 273 build.. short block and ported heads are all done.. previous engine rocked before and with a fresh rebuild and ported heads now, it will rock even more. LOL
This 273 will be finished.
