Double timing chain with pully ?
Double timing chain with pully ? Just wondering if any1 has problems with clearance between an adjustable timing chain and a under-drive crank pulley, i have the March pulley....What would be the best timing chain set for my setup....Thanx guys
well, i had an slp double roller, ported ls6 oil pump, and the march underdrive crank pulley. first i had to get the pulley machined to fit properly. then after driving it for 8 months, when i opened it back up to swap cams, the chain had been rubbing against the timing cover, as it wore a ring on the inside. the car had also been running like ****, and my tach didnt work during that time... then i swapped to an ls2 chain, kept the oil pump, and put the stock pulley back on and everything was back to normal... i would say go with the ls2 chain, as it might save you a headache
LS2 Chain here also, I think double rollers are over kill on street cars anyhow. More problems than benifits... Besides, you can get yourself a LS2 chain for 35 bucks... can't beat that...
