Ok so I have another thread in here about troubles with my La based 408 stroker having troubles staying running in gear at low rpm, and what appears to be a fouling issue of the plugs. It’s a blueprint 408, that I bought never run, from a 3rd party. The tech from blueprint got back to me with some inquiries I had about the motor build, and in his response he said “timing needs to be mechanical only, no vacuum advanced used.”
When I got my motor, it has an msd distributor in it with vacuum...
Riddle me this..mechanical vs vacuum advance
