OPINION ON DISTRIBUTOR

That's right they tell you the canister only puts in 10 but it actually puts in 20 degrees at the crank.
mderoy340 directed me to a web site on a hot rod forum that shows a pic of someone that fabricated a small plate to limit it which i probably will make.It just sucks you pay four hundred dollars for a distributor with vac advance and you can not adjust it for what you want. Pertronix has a vac that is adjustable and so does mallory.
