[DMCForum] Rich's ignition



Can adjust my CPR because it isn't stock... (am afraid Mr Historian is
stuck with whatever pressure his bi-metal plates produce)

Don't dismiss your crappy ignition so quickly. Louie G at least will
back me up on this one: BUY YOURSELF SOME DECENT COMPONENTS. Even
stock would be better than what you're running now. At speed you don't
have a lot of time to explode mixture. Yellow spark isn't going to do it.

Worst experience in my life was screwing around with low voltage
ignition (factory spec) on 1969 engine I transplanted in one of my
Lincolns. Mistakenly listened to mechanic buddy who convinced me to
keep everything stock. While he was correct Re: camshaft, valves, etc,
ignition was neverending headache. Simply converting to high voltage
electronic (breakerless) TOTALLY reinvented the car. Convinced me then
to swap coils on them all.

Will probably drive one of the Lincolns next time I come up there. We
can throw its coil on your car and see if you don't eat your words.
Still have the Bosch plugs I swapped out of the DeLo. Will give them
to you to get rid of those stupid Champions.

Re: timing while spark advance connected -- in theory you'd be OK *IF*
spark advance cut off solenoid is working. If solenoid is letting
vacuum through, car is in fact way retarded. Watch timing mark as
throttle plates open. 13 degrees idling with full vacuum will probably
jump past TDC as it drops.

Re: steering rack -- all my other vehicles are center link so you
might need to check with rack & pinion owners. Outer tie rods look
conventional enough, but have no idea what's inside those boots. FWIW
I can replace everything from pittman arm down for $100. See now why
I'm glad ratio of Lincolns to DeLoreans is 5:1 and not other way around...

Re: 302 in a DeLorean -- would never work without a lot of ballast up
front. Engine is behind rear axles. Cast iron would tip car backwards
and lift front wheels off ground. Better leave men's engines in men's
cars and continue debugging your PRV (excuse me: better leave boys'
engines in boys' cars. 460 is a man's engine).
