they are all 6 port engines.....the Spec 3 is a 6 port, the Spec 2 is a 6 port, the BigRed is a 6 port......
I have been running a LRP 30 for a bit.... IMO learn to tune better and buy a Picco 28...LRP 30 is kinda lame when its stock, we really notice its lack of RPM
Then what's the difference exactly between a Spec 2 and a Spec 3??
