I think Timmy's estamates are bit on the high side. I am going to guess maybe 10 hp and 10-15 tq. The 305's just don't respond all that to mods, the heads are so restrictive. I think you will notice the gain but it's not going to into a tire shredding monster with just a carb and intake.
I agree. I have no doubt you will feel the difference, but I would guess no more than 20 HP, at least without a cam change. Not sure a came would help alot, either.

I also would not be surprised if you have some challenges ahead of you getting the jet size right. Hopefully it comes with jets about the right size, but don't be too surprised if you have to fiddle with several sizes for primaries and secondaries before you get it just right.
