Perfect. Thank you. I'm freshening up a 273 right now too.

The highlighted specs on the chart are for a Isky E-4 cam which is close to a stock HP-273 cam. I don't have the stock specs handy and the in-laws computer I'm on is slow as molasses. I'll post them if I can. tmm

Looking at the "66" service manual 2 bbl 273 = intake duration 240 degrees
exhaust duration 240 degrees
valve lift .395'' intake
valve lift .405 exhaust
valve overlap 16 degrees
4 bbl 273= intake duration 248 degrees
exhaust duration 248 degrees
valve lift .415 intake
valve lift .425 exhaust
valve overlap 26 degrees

The 273 HP cam can be bought at Egge in CA. Easy way out.
