    Mabey he means Hi Performance 305. Anyway, the two chambered flows are the load ones three chambers are the softer ones.

    The best thing I ever did to my old stock 305 is give it a tune up and a K&N filter..not just the charger but I converted it over to the open chrome filter assembly. The cat was getting plugged up so I cut it off and put in a straight pipe and a glasspack. You can always advance the timing for more power but dont go too far it will cause a ping.

    How many miles on it ? If it's close to around 70,000 be prepared to replace the cam. They go out around then. It would be a great time to install a high performance one at that time.

    How about a new Edelbrock Performer intake and a Performer 600 carb? Those two things along with headers and a good airfilter makes your engine breath a little easier, and should be good for an additional 30-40 hp, or so.
