    non-HO cams

    HEy, not that I'm going to be doing this for some time, but does anyone have any suggestions on what cam to use in a non-HO 302. It's an EFI motor, figuring on a 65mm TB, stock intake, stock heads, and shorty headers going to a mandrel bent 2.25" dual exhaust with Flowmaster Delta 40's out back. I'm looking for a cam that can give me low end torque, with mid-high range power.

    What exactly do you want to do? If you do the complete HO conversion, you'll have an extra 40-50 rwhp no problem. It's hard to argue with those numbers using factory parts people would probably give away.

      Yeah.......Explorer/Truck or Mustang/Mark HO cam. Forget about a decent roller cam for a decent price with a non-HO firing order. It makes no sense to go backwards to a flat tappet cam. HO ECM's are cheap.

          So basically if I should go with a HO cam, I might as well look into FRPP's roller cam selection

          I like the E303:http://www.fordracingparts.com/parts...tKeyField=1329

          Also...I know I sound like an idiot, but to change to the HO firing order, I'm going to need to replace my ECM?

            the e cam is going to require you run a mass air ecm
            yes to change over to a ho cam you need a ho ecm.......mark 7 ecm will retain your cruise control
            i'm making 221 rwhp with a stock ho cam

              That is a nice find.......essentially a HO cam with standard firing order.... the issue would still be that the factory ECM would not be able to take advantage of the additional power potential without a chip.

                I guess some will have to install the cam so we can find out.

                the cam is not that wild, so the stock ECM should be able to keep up.

                    If its essentially HO spec, but non-HO firing order, I wonder if just tossing a set of 19 lb injectors in would do it. Truck engines have a non-HO firing order and run the 19 lb injectors, but thats also the funky batch-fire stuff and they have e7 heads.

                    It would run rich as the ECU doesn't know that you put 19's in.

                      It isn't just a matter of keeping up. The whole reason to add the cam is to increase performance. The factory maps suck. You loose power dropping from a stick Mustang ECM to an automatic ECM. Imagine the drop to a CV/GM ECM. It is much less expensive to put a Mark or Mustang computer with a factory HO cam in the engine and the net power gains are much more.

                              err, i never said it would run rich, i asked if fatter injectors would work with a HO spec but non-HO firing order cam.
