The problem is those cams are such old lazy grinds and you should be able to get something much better these days.
I suggest you have a look at what Kelford Cams in NZ has to offer off the shelf. https://www.kelfordcams.com/global/camshafts/holden/efi-304-v8
To make a simple comparison of what I suggest,
The Crane 268 is,
206°/206° @ .050" and 268°/268° advertised (.006") duration on 112lsa with .448" valve lift
The equivalent Kelfords grind is the 170A
206°/206° @ 0.050 but only 256°/256° advertised duration on 114lsa with .440" valve lift
The Kelfords grind with exactly same .050" duration will perform better right through the rpm range (with the same compression) because of the shorter advertised duration (which means the valve seats earlier) and therefore bleeds off less cylinder pressure which means better cylinder pressure and a better bang for your buck.
IMHO using something like an (old) Crane or Crow off the shelf grinds you are leaving power/torque on the table especially if you are using stock or near stock compression ratios!
I only run kelford Camtech sticks have done since I was a kid getting Briggs and Stratton and dirtbike cams done lol here's the D camshaft [email protected]" great with bananas and twin 2.5" exhaust and 2500 stall was a great cam for daily driving nice sound and had the grunt to back it up
