what solid cam is equivalent to a hyd 268 ?

what solid cam are you all using that is equivalent to a hyd 268 cam ? I have a big erson solid 510 lift - 284 dur, 2000-7200 rpm range in it now , just does not have the bottom end torque and takes too long to whind up.
it is going into a non commando 273 . 4 speed, headers , ld340, 650 dp, electronic ign, low compression 4 relief pistons, stock closed chamber 920 heads and 3.55 gears.
everyone talks about the 268 cam here on fabo.
The 268 is a popular small block cam. Works great with a mild 340/360. Works well in 318's too but that cam in a automatic is borderline too big with a stock converter. It has been done but tuning is tricky. Your 273 2 barrel is easy to over cam and if you do there goes your bottom end. Good you have a 4 speed so you don't have to mess with torque converters.
