Cloyes SBC timing chain on a LT1

In order to run the Cloyes Double Roller timing chain (part# 9-3145) or anyother SBC timing chian to fit you must first covert to a 95+ opti.  You need to remove all the water pump drive stuff from under the timing cover, and install an elec pump.  Doing these mods allows you to run a $79 timing chain that is stronger than the LT4 extreme duty!!
