MoParx if it doesn’t have good spark what could the cause be?

I obviously have put on the new FBO box, and coil, bypassed ballast resistor and ensured the engine has a good ground to the body. The distributor shaft is not broke (I confirmed that today). The cap and rotor look good too. I have new unused set of MSD from a different small block project I could put on but I suspect the Mallory wires on it aren’t the issue.

If it warms up enough tomorrow I’m going to ensure the rotor turns as the engine is cranked, ensure timing is correct, ensure the engine is at tdc, check firing order of plug wires is correct.


Things I have accomplished with the 30 degree weather we’ve been having...
Replaced he fuel lines
New battery in
Nitrous system off of engine
New FBO stuff on


without seeing under the dash, and looking at the bulkhead connectors, it "may" be a hidden [as in, yet to be detected] wiring problem. as you have said your brother [brother-in-law ?] has been playing with it, who knows exactly what may, or may not, have been done wiring wise.
