Currently i have a Cloyes true double roller timing chain. I have had an on going issure with burning up opti bearings. Another board member says he was experiencing problems with the same and said it was the cloyes. something about the thickness of the cloyes putting pressure on the opti bearings

I recently replaced my opti, shimed the new one with some washers...runs great again...but after 200 miles it making the same noise that it made befoe the first one crapped out.....


Having all that back ground... I am wondering it it would be fine to run my stock timing set.
My car is a all forged 4340 355 running 12# of boost and about 520 rwhp.

my cam is a 214/224 .565/.605'' 114 with cc977 springs. open seat pressure is around 400#.
Max rpm is 6500

Let me know what yall think. also sugjesting for other timing chains that are made for lt2s and have no known isues with optis let me know.

 

I wouldnt trust the stock timing set with an all forged blower setup making 500+rwhp. Why not just get an LT4 extreme duty set to protect that investment of yours?
