Ok, I pulled the trigger on the Sniper EFI. Was deciding between the Holley and Edelbrock products. Went with the former because of the cost.
Unlike fellow Calgarian Angus66, I aimed at a more complicated scope: engine stays in, all new ignition with time control, the fuel pump in the tank.
The fuel tank, lines and the TB part are done, put the distributor in. "While there", fixed a tired drive shaft U-joint, replaced original rear shocks (still shockingly capable considering the age) and did a bit of anti-corrosion touch-ups.
Even though I pulled the radiator and the fan out, I am still on the fence over replacing the timing sproket and chain. Even though it is 100% original (nylon?), it shows 0 slack. Think I get to it once I have the EFI running, over next winter, when I finally get to install the maxxjax lift.
Removing the fuel tank was so far the most physically challenging part. The original owner did not know or trust threaded fasteners, so the towhitch, handcrafted from the 8-10 mm steel (some 25 kilos or more) was welded in. Cutting the damn thing out to drop the tank I said many nasty things about the poor fella. Hope he's already long gone and his karma did not suffer.
But I digress. Once all done, I plan to do a writeup so that an amateur like me could have some second thoughts before following the same path. There are certain obstacles to overcome.
For now though, I am struggling with the electrics (which I am not very good with and the ambiguity of Holley manuals and videos not helping much).
Aside from the ignition setup (magnetic pick up distributor with the coil driver wiring), I need to get switched ignition (+) for the coil and some other stuff. The wiring is sort of stock (except Lean Burn was removed eons ago). There are no emission controls (I only see PCV and the heat riser flap).
Any suggestions? I do have the 2-tome shop manual with schematics, so if someone could point out at a proper page/part of circuit - much appreciated.
Also, Sniper manual calls for 15 degrees BTDC when setting the distributor, but if I read the specs on the Canadian 400 big block correctly, it should be 20 degrees for the basic setup. I plan to call Holley tech support with this, but some second opinions are very much welcome as well.
