So ive done this like you say by running the tach signal from hei distributor to the purple wire on the harness. Ran, but very very rich. Perhaps an aftermarket computer will work like that, but not an oem gm one. There is a way to "trick" the computer to an extent, but it wont make proper air fuel adjustments. Ultimately don't recommend this whatsoever. Not opposed to the hei mechanical advance, but it just doesn't jive without changing the ignition module. And then you have at minimum the brown/black jumper wire disconnected, so the computer wont compute like it supposed to.
I’m considering a vortec swap into my TBi truck.. did you notice a low end torque loss? Did you do any other mods to fuel system? Did you have computer chip tune or is that why you did the hei to adjust timing? Did it not run right at first? Awesome video!!
hell yeah man this is great just did this on my 95 350, just was wondering if you messed with the timing or what degrees you left ur timing mark at? Also now 2 months later how does it work ?
