I'm ready to start putting this thing together. got my test stand engine running on all of the original equipment (runs good too).

what you dont see in the pic is the radiator setup I have for the test engine.

I believe I have all the parts now as well that I need. several distributors with 7 or 8 pin modules, a 235 hei distributor.

wiring harness. couple of computers, one of each size tbi unit. sensors.

is any of it good? I'm about to find out!

current plan:
get the TBI unit on the engine and running while retaining the original points distributor (so just use TBI for fueling at this point).

then I will change to the HEI distributor and get the timing set correct with that. then convert using one of the computer controls modules so the HEI is controlled by the TBI and lock out the vacuum advance.

the reason I'm doing it this way is because the carb I have "works" but it leaks (cracked housing) and it located above the exhaust manifold and I'm not really comfortable running it long with gas dripping on the manifold.

I'm putting my old thread here for my own reference as well as the wiring diagram link so I dont have to find my old thread info:

I'm going to use the 4.3 ecu for this.

I believe the only sensors I need for fueling purposes are as follows:
TPS, IACV, MAP sensor. I dont believe I need the EGR sensor and since its not running the ignition at first I do not need the ESC or ignition module.

is that thinking correct? I assume it will be in limp mode with a stock ecu though but thats ok I think just to get it running and then I can swap the HEI on and such.

once my grand plan is done, then the chipped ecu in the padded envelope can be hooked in and I start finalizing the tune. Or am I going about this wrong? it makes sense to me.20240305_173755.jpg
