Got it .
but now that 278-280 dur is getting pretty close to what I have now, right ? where would be a sweet spot for the lift then?

No, I am not saying that would be a good "match" for your application. Just that it is about the same as a 268 hydraulic. I think that a 278-280 solid is pretty huge for a 273. That E4 cam is supposed to be very good.
