Thread: Bigger injectors available for original 502-20S?

    Default Bigger injectors available for original 502-20S?

    I'm looking to install it to finish off a budget-build (I'm laid off) mild 351 SBC in an 81 Vette that as built should be capable of around 300 hp just under 5000 rpm, with a max of 5500 rpm, so the 670 cfm should be adequate but the 80 lb injectors might be a little small.

    By any chance are there larger injectors that will fit that unit?

    I have a wideband I've had for awhile I'm going to switch to that car so I can see where I'm at and to help tune the A/F.

    Thanks!

    If you're referring to the old style B2 injectors (black round tops), there were larger size injectors available, however if I recall correctly, they weren't sold through Holley.
