Thread: Just to confirm the pulley size with my current growing list of junk

The extreme energy cam is an OK cam it gives a nice broad tourqe range but falls off on the top end their are better cams to be sure but for a DD it wouldn't be a bad choice ,going with a genv is always a good idea but unlesss you are going to IC removing the H bar is a waste of time ,I would say with a modular pulley setup start with a 3.4" to be on the safe side and go from there ,don't forget a new timing chain and tensioner and I believe if you are not going to IC some type of CAI would be a benefit just keep the tubing large 3 1/2" or 4" and limit the bends also use as large a K&N filter that you can fit in there .

Once you are in the 3.4 gen v or 3.2 gen III range open cone is the best. I would also run a dry flow filter. Not K&N
