greets, i have been inactive for a couple months, was going to start my 3800sc project but had to buy a daily driver and save up some money first..... anyways.......


for the 3800sc guys running the xp cam, do you recommend me going 105 and single chain or 130 and double roller chain? what are you guys running on your setups? someone chime in, I am going to purchase the XP cam kit from zzp soon. thanks

I run the XP with 105 springs and stock chain/tensioner. Have been runnjng this setup for 70K miles and will be pulling setup soon to swap in a new stock chain/ tensioner along with new 105 Crow springs. Dont go with CompCam springs as failures have been seen since there plant was relocated.

I have heard bad things about using the stock chain even on 105 springs and that it stretches/breaks the tensioner. The engine I pulled has 130000 kilometres on it too. Is it a safer bet to go double?

I have read more about ppl busting aftermarket chains then stock chains myself. I have not had any issues but cant comment on stretch till I pull my setup to swap springs/chain.

My understanding is that 130# and higher definitely have to have the double roller timing chain but under that is some what optional. Personally I would go with the double roller chain but have built a few over the years for customers with just a new stock chain and they are still driving around years later.
