I just finished a very successful engine swap in my 1985 silverado.I ditched the old 305 paperweight and installed a 350 but i am using the 305 distributor.The 350 is a real brute and runs very strong but am i short-changing myself on performance with the 305 distributor? I'm just wondering if there is any performance difference between the two factory distributors since there are more cubic inches in the 350.thanks.

The curve may be slightly different from that of a 350 dizzy but not that much to matter unless your trying to squeeze every available hp from the engine. I don't know if your running a carb or inj' with an ECU in your truck. I guess it would make more of a difference if you had a 305 ECU operating a 350 engine that the dizzy it'self.

I will work fine stock. I would recommend u visit performance distributers or summit racing and add the coil, module, and brass terminal dist cap/rotor kit they sell. It will help "liven" things up a bit!

It's not manditory, heck, u could add it on later down the road as well...
