Re: cam question

i want a lil bit of a lopey idle nothing serious though. about re-tuneing. i do plan on either takeing it to a dyno shop that does tuneing, or one day learning how to do it. that might come after i build a 350 for this bird. about the header size, yeah i know it does sound big for a 305, but it sounds so sweet, and when i installed them and ran the car it felt stronger than the other headers i had which were the dynomax a.i.r. headers and they were smaller. i was thinking about getting the compcam xfi 268 cam. i listened to the sound clip from the other guys 'bird which he posted in the forum and i loved that sound. now granite he has some other mods to his engine. and i do plan on building a 350 one of these days whenever finances get better.
