Ordering cam today, do I need a double roller timing set?
If the ASP pulley was made after aug of 03 you dont have to worry about machinng. Ijust did a cam swap and didnt have nearly as much trouble putting onthe double roller as you guys claim. I dropped the pan 1/2" took the pump off put the chain on and went from there. Simple and easy. most of the newer pulleys are allready machined for clearance for double rollers

Too tight not really that good IMO, too loose either. It just needs to be right.
Too tight will increase your front cam bearing wear and put unnecessary downforce on the cam, limiting the oiling to the six oclock position on the bearing.
Unless you have a 750rwhp monster, it's overkill. But this is MO from my experiences.

I went with the double Rollmaster because I had 66,000 miles on my motor. If it had under 30,000 I would have left the stock one on there, would have saved me 3 hours. It wasn't hard, just frustrating getting the o-ring in properly. At least I didn't have the pain of having zero oil pressure and taking the front of the engine back apart.
As far as replacing the chain, I figured the double was a nice piece. It's not too loose or too tight, it has some slack. The spacers are no big deal, just be careful on how the drivers side spacer goes in. Big kicker is that it only costs $91. I would never replace just the chain, it's wise to always replace the gears when you put in a new chain.
Thanks,
