  • What cam choice?

    Have a 305 with headers exhaust with stock converter and auto trans. Looked around but everyone keeps saying get a 350, if I could I would. Found many Ideas, but wanted to hear it from the horses mouth. If you have a 305 with a cam, let me know what you are running and how it runs and sounds. Just looking for help is all. Thanks in advance

    Im not much of professional help but from what I heard with cams you'll need to upgrade the converter. Could be wrong..

      Bigger cams work better with a higher stall, but it isn't necessary with all cam swaps. I wouldn't spend 250-300 bucks on a cam for that 305. I'd find a used LT1 cam and shorten the dowel. Get some cheap 1.6 roller rockers or roller tipped rockers.

      The reason I say this is because those heads are going to negate a nice cam.

          stock LT1 cam is a good upgrade for 305s... i personally wouldnt throw money at a 305. Spray it with nitrous til it blows (it will take more nitrous than you think) then put a block with a proper bore size in its place.

            Get a LT1 cam and spray it till it blows up like Joel said! I once met a guy running low 12's with a lt1 cam and a 200 shot with a 305

              Btw the dowel is press fit in so you don't need to cut it, just yank it.

                Hmm.. thanks guys! I have thought about the lt1 cam, wanted a little lobe to it ya know. But you are probably right just to stick with the knowns facts of the lt1 cam. Spray a tbi? with like a plate? Wouldnt I have to get different injectors and even retard the timing? Not sure on that.

                  Just make sure you get a wet kit - TBI plate or nozzles. If you plan to spray 125 or less you can keep stock pump/injectors/timing...well, that's what Nitrous Express says...personally I'd back off the timing a bit.
