i made this post a few days ago and i want to give some of those experts out there a little more knowledege about my engine. Its a 74-75 model 350 engine in a 81 buick regal. looking to get more power out of it. Seems like it has a sort of slow take off. it has headers 1.5 comp roller rockers, edel 650 carb, air gap intake, 292 comp cam, 9 to 1 compression ratio, hooked up to a 350 tranny with 2800 stall. hadnt did anything to the rear end yet but im told this will help alot. It has regular gm heads 72cc. going to change the heads in a couple months. What is the best exhaust to put on it ?it has dual right now but they aren't flowmaster or any thing looking for a better deeper sound. it has cats on the duals right now i was told to cut them off because its to restricted for that and i have a way of getting around the emission test. please give me some help guys!!! i have $2000 in the engine right now and i dont look to spend no more than maybe another grand.

The gear suggested earlier will make a tremedous difference. One problem I see right away though is too much cam for the CR. That 292 needs at the bare minimum 9.8:1+ If you can get around emissions, definitly get rid of the cats. Try some flowmasters for a flee flowing exhaust and a deep sound. Be conservative on pipe size like 2 1/2 max. Try to find you some early casting heads with a 64cc chamber, or better if you can find a set of vortecs but then it cost extra money for a new intake to fit and either machine work or a set of springs I seen posted that omit the need for machine work. If you look around you can find some camel humps pretty cheap that can be home ported to make decent flow numbers for a street engine. One more thing to do is run a good quench area. Measure how for your pistons are in the bore and use a head gasket that will put you in the range of .037-.041 head to piston distance.
