what all do you need to do this and going carb? what does a good strocker kit cost? will a 750 demon be big and to big for a bolt on 302? its going to be a 408? think

IMO a vacuum secondary demon could be used on a 302 with a tighter secondary spring to eliminate the launch bog until you got around to doing the 351 or 347 or whatever..if thats what you are asking. And at that point you could put a lighter spring in the secondary and be ok. It also matters if it is a stick car or auto as to how well it will work. You are gonna hear that you need a 600 or 650 but I feel a 750 would be a good choice if you are gonna put some cubic inch in it at some point and the carb would be expensive to replace. I also recommend the vacuum secondaries over the mechanical secondaries (double pumper) for most people because of ease of adjustments. The mechanical carbs are very adjustable and alot for most people to get on to without alot of frustration. Also the vacuum model would be a little more friendly for street use and occasional strip pass. IMO
