it is a big deal adam, sorry for the banana reply but your profile kinda pi.... me off,lol electonic high performance electronic ignition distributor with performance curve and adjustable vac. advance .170,198 and 225 6 engines part number p3690789 3.9 litre v-6 p4529402 they even make the fast curve distributors for the little engines. these ar M.P. parts numbers,,,,,,,,if ya deny it why dont ya just try it,.ancient chinese secret but much more easy than the M.P method. the post tells a great way of gaining some decent low end and no it doesnt lean out or burn hotter ,nor does it make the car run hot. forget initial on anything performance related ,say anything 14seconds or quicker and this method works like a charm.Ya just have to forget initial .I run 13.5 to 1 and have no starting problems. the advance in the distributor actually retards the ignition for easier starts. meaningless. heck, they sell the kit for the slant 6s and the 3.9 this is just switching over its not performance.its what M.P. sells,there are no other choices as their the best. its mainly changing from points to electronic or lean burn to electronic. so try my method out and youll feel the difference ,betcha. ps ,they do make adjustable knob timing lights.think about you 2nd post up adam, yes the advance curve is important and when it all comes in at is also important. the total means all and will tell you your given ignition advance by revving to when your total advance is in fully and your at your desired degrees on the damper. the initial will be what it is but its normally around 14 to 18 but it just makes your car a tad bit better on performance.so your going to run 27 total to achieve 8 initial? that sux for speed.remember ,the spark advance or vacuum actually retards the engine on startup and its not a problem. can you change your profile into a pretty girl rather than a demonic lookin gorilla? lol take care, to each their own .
