What camshaft spec for 425 hp

When you ran that Crower cam, how heavy was your car?

Some where around 3400 with a full tank.

The cam I was told was just a comp 218/218. I know the guy who ported those 318 heads as I take my stuff to him to have it flowed and he verified the details but eluded to the fact it had "much less" valve than my 1.9 which to me is code for stock. This guys lets very little out about what he does but CHI carries a head with his port design so he obviously knows what he's doing.

Looking at the thread on Mike becks cam change he went from a 216/228 to a 234/242 and didn't really pick up the ET. So what's going on there?

he rest of the combo:

'73 Duster, 3120 pounds with my fat *** in it.
360+030, around 9.5:1, shaved and ported X heads, Edelbrock Performer RPM, Holley 750HP, 727, PTC 9.5" converter, 8-1/4 with 3.91 gears.

Previously the best 60' was a 1.69, on my 2nd run on this day the 60' was a 1.67 (I think, I don't have the slip in front of me).

You would think he has everything to run a whole lot quicker but it didn't.
