guys, john is leaving a few things out here too.....
its an auto with 4.10s, a crappy 2000 stall converter (which hes putting back in the car with the worked motor) and he MIGHT BE USING A TWEECER.
so, with that being said, heres my reply: let him use the b303, get decent, but lower HP results than what he expected and try to be happy with it.
now, if he would listen to me, heres what he should do: get a 3500 stall (hes gonna be using a sticky tire), save for the tweecer and use a comp cams XE series cam, like the 268 or so.
John, talk to KillerCanary and see what he recomends. Call Comp Cams, email Jay Allen (who made my custom cam) and get some PROFESSIONAL HELP before you put ported heads/intake with an undersized cam!!!!
