Ignition Retard
 

Is there anyway,other than a programable ignition box/computer to retard timing in just 1 or 2 cyls.?

MSD has the selector but you have to move it manually.

I looked all over their stuff, all I can find are ways to change the timing in all cyl.s
I need to change just 1 or 2 cyls. ONLY.

What would be the effect of a LONG lpug wire on the cyl. in question?
Juice takes time to get there,would probably have to be pretty long,4-6 ft.?

I dont think you would affect timing enough to notice as spark travels in miliseconds. I know Ishmael performance had an 8 pack coil set up back in the day that you could do what your asking to do. A very easy setup that could be recreated with a bunch of coils. Worked on a points ignition too.

Tell me why you need to retard only a couple of cyd????:)

Poor flow in #4 runner,causing detonation.
probably just going to change compression in that cyl.,but was looking for alterantive.

Before there were programmable boxes, the NASCAR engine builders would bend the tangs on the distributor reluctor for the cylinders they wanted to retard or advance, then check the results by putting a timimg light on each cylinder. I guess it was trial and error until they got the right amount of change.

Why not just put a hotter or colder plug in that cylinder.

Poor flow??? What cyd's and whats the firing order Ford,Chevy??Are you using a carb?? If it's lean in those cyds would more fuel help?? This can be done..

440 Mopar,Edelbrock 6bbl intake. Of course Holley 2300 carbs.
1-8-4-3-6-5-7-2
Only #4 breaks the plug.
