Rebuilding a 65 273..I need some help.

Yur asking the wrong guy....... I run a 360,lol
A 220/110 cam is a nice cam in a 360 if a little conservative.
To run a 220 FT-hydro in a 273, I think the builder will need to have all his ducks in a row, and packed together tightly,lol..

The lifters should get it closer to 205 at idle. I'm hoping that leaves it drivable still.
