fuel question for head & cam swap Hi, I'm about to put a 243 heads and the futral 224/224,/588/588,114 cam with borla catback exhaust,lid,ls6 intake with ported tb in my 99 ls1 firebird. I wanted to know if my stock fuel pump handle this upgrade? I know the stock 26lb injector is probably borderline,but don't know about pump. Whats the max hp on the pump? Lets say i change the pump to the Walbro and after do i need to do anything else besides the pump? Like doing something to the fuel pressure regulator? PLease help I'm a newbie

Your pump will be borderline as well max is about 400-430rwhp. I would replace it with the Walbro and that should cut it for your setup. I have direct replacment Walbro's for $149.99 and optional hotwire kit $59.99
