I was nervous about the cam being too big. I kept seeing cams of this size being recommended for 400+cid engines and I know that 100 cubic inches can soak up quite a bit of cam. Over all I'm quite happy with the manners of this cam in the 305. I think the more aggressive ramp profiles are helping keep the "street manners" quite tame. I was impressed with how smoothly it idles.
I considered throwing the edelbrock 9906 I have on the shelf on there, but for this truck I think the quadrajet is a better option. The edelbrock and afb are simpler carbs to work on and understand but the quadrajet really is a much better carb.
