Thread: Waste-Fire Question

  1. #1

    Default Waste-Fire Question

    Chevy V8, Dominator, Dual Sync Distributor, Waste-Fire 556-101 coils. When installing the Dual Sync Distributor the instructions say to set the crankshaft to 50° BTDC on the compression stroke on cylinder #1. This is the way I setup my engine, but then I was thinking (perhaps a bad thing) that since this is a Waste-Fire system does the initial 50° BTDC setting need to be on the compression stroke?

    I'd say follow the instructions. You'll have #1 on compression, and the paired cylinder of #6 is on the exhaust stroke. Every engine would be setup starting from #1. Gary

    Setting #1 cylinder BTDC on the compression stroke is just good practice. I installed my Holley EFI Waste-Spark ignition system (LINK) this way, even before I upgraded to sequential injection (LINK). Why do it any other way?

    It might work either way for waste-fire, but down the road you might switch to sequential and then it won't work. I agree that following the instructions makes the most sense.
