In my opinion the canadian intakes are nice but not worth the money guys are asking for them. If you can get one cheap run it, if not put your time and money in other areas of your car. just my opinion. They are better but the gains aren't worth the headache of finding one or the money spent to get it.

Are you locked into the 305 due to rules? If not, and if the budget permits, get a 350, the 305 and the 350 have the same stroke, however, the bore of a 350 is 4.000 the bore on the 305 bored out is only 3.776. a stock 350 would be like boring your 305 out another .224 (almost a quarter of an inch) then add to that if you wanted to bore the 350 out. If you must stick with the 305, and if your allowed (no cheating now) 2.02/1.60 valves, porting your intake runners to match your intake gasket and port your heads to match the intake gasket, and maybe a carb spacer, not to big, an inch would be a good place to start, jet your carb a pinch rich, these are each worth a little bit of power, The head work is of course going to give you the most noticeable gain, the carb work is only going to aid a littlbit. what rpm are you turning in the corners and down the straight? if you're above 6,000 peak your gear is going to be o.k., if you're below that, maybe a some gear will help ( make sure you have a cam with the power band up there though) hope it helps and good luck.
