Racer Brown ST-21

Looks like the specs say 10.5 or better. 4.10 gears. You would probably be ok with the 3.91's.

286 is probably advertised duration, 254 is @.050

Yea I seen that but could 10.5 static be ok for street? if this cam bleeds off compression? Thanks physhy. i thaught my 3.91's would work with the close ratio trans and smallish tires.

I'll buy a new cam if i have too but i would rather save the money for new heads or have the smogers ported.
