G'day Pete sorry for the late reply I only just noticed this message. I have a dry kit spraying straight into the throttle body, its a cheap setup but it works and its reliable. I have had no drama's with blowing manifolds off etc like people do with wet shots. I havent done any work too the engine apart from, cam, valve springs, double row chain and pushrods. The bottom end and heads are stock. Its ok for a small shot on a stocky just dont get carried away and keep increasing the shot too make more power cause it will end badly a bit like regularly pumping 15 psi of boost into a stocky it wont last long. Also make sure you have a good fuel sys, fueling with gas is very important if you want the engine too last.
