bigger cam more timing?
im trying to set my timing. i havent really done this before. the engine is a 302 hipo and all i relly know about it is a few mechanics have told me that there is a big cam, and that its been bored 30 over. i notice that the book says the year engine i have (68 302) is supposed to be 6. with a bigger cam and the engine bored out, am i supposed to increase the timing? i did set it to 6 but the engine ran like crap. I then increased it to 8 and it helped a little, but still ran pretty bad. any advise would be great!
