Is there a stand alone timing control module

There's at least 1 dedicated product but it "may" require a dedicated distributor. I don't pay attention to this stuff because it is so expensive. The ones I've seen, support mgpmike above. You are well on the way to buying an EFI controller by the time you pay for an "ignition only" device. A guy has to wonder, "without EFI, then why?"

I will use it on a 440 RV motor with 413rv heads that I am building. I am pushing the limits of compression for running 87 swill and want to have it to pull some timing if needed. I want the higher compression for efficiency and because it will be a dual fuel motor running on CNG when available.
