  • Injector size

    Combo is a turbo 289, EFI converted handled by MS. Plan on running pump gas at around 450-500hp.

    Will 42's suffice or be too big or not big enough?

    Should be good. I run 42s on my 302 with a novi 2000 and put down right at 500 rwhp with no issues

      They will work, albeit at the top end of their duty cycle (which isn't typically recommended).

            60's would be safer but I think you can get by with the 42's. Watch your AFR and duty cycles. With the megasquirt at least you have options to log and help keep the tune safe.

                      Id go with new gt500 injectors. They are 52# i believe. Readily available and cheap.

                        Looks like I'm going 80's..... Might as well go E85 at this point

                          Dont lets yours end up like keiths with the e85. My junk will sit for extended amounts of time so im stickingto the ol best shitty pump gas i can get with a few gallons of 112 thrown in.

                            Ya, been looking at different intercooler ideas. I don't have the fuel system to support E85. My pump is rated at 600hp pump gas or 300 e85..... Sooooooooo

                              I made the switch back to 93. If Holly ever comes out with an ethanol vontent based fuel table adjustment I will go back to having an e85 tune.
