Edelbrock parts
Do the edelbrock runners and intake make much of a difference in a 305s performance? And what about a cat back exhaust?

Re: Edelbrock parts
Wont really make any difference at all. The factory TPI system was designed around the 305 air flow data so your current runners are fine for a mild 305. On a 350 on the other hand that's a different story but for a 305 its money better spent else where.
