Well i got the pertronix setup and me and my dads friend put it in. Before my truck was running pretty good.. but i decided to go and get this so it'll run even better. Well it turns out my timing was off 25 degrees..... I know ford says to put it at 6 but wouldnt it like 10 better, or would it? it has 190,000. its a 68 f100 360. But right now the truck starts right away but the only problem is when i stop sorda fast... it will buck a little at idle and sound like it wants to shut off... but it hasnt yet. Why would this be... the timing needs more adjusting maybe??? thanks.

Each engine is different and it really depends on the mods and other factors. Generally, more advance is better until it starts to ping under load on a warm day.

As for it trying to die when you stop, I bet you have the stock 2v carb don't you? It tends to throw the fuel forward when you stop and starves the engine, has nothing to do with timming. I have one of those trucks and it does the same thing, a fuel bowl baffle or anti slosh sponge will help.

Also, don't trust the timming marks, they slip where the rubber part is on the balancer.
