i have a 1966 olds dynamic 88 ragtop with a modified 425. mild crane can and bored 30 over. its got about 10k since the build. my problem is it wont stay in time, i reset the the ignition timing (seems to be right at 15* advanced with cam) run around the block and timing is off again. the ignition is fairly stock points and condenser. also looking for advice on where to start with dual exaust mods..this single is killing my horsepower...do they make a bolt on?
