318 2bbl manifold swap with OE cam - worth it?

I agree with the others if you need maximum power go to a 360 or 340. It all depends on what you want, mine runs mid 15's with a basicly stock 318 except for 340 cam and springs old streetmaster intake and 600 holley, good dual exhaust and some tuning. Also has transgo TF-2 which helps shave a couple of tenths off. I am still running the original gearing in the 7 1/4 2.76 and can get 20 mpg on the highway no problem. I am in the process of building an 8 3/4 for it and will probably run 3.23 or 3.55 gears and expect I'll just get into the 14's with that as my build is very mild. Even a 340 will be a dog with 2.76 gearing. If you motor is in good shape, doesent use alot of oil and compresion is good and oil pressure is good, bolt ons will work just fine. You cant expect too much with a tired motor no matter what you start with. If I had it to do over again I would have done the rear end first. I saw a test once where a stock 318 2bbl dart with 4.56 gearing ran 14.88. You will need the rear end upgrade if you plan on doing anything more then just crusing.
