Ok, I hear word of the Cloyes double roller but do I need a electric pump for it? Im basically looking for an alternative to the pricey LT4 ED timing set but if there is nothing out there better or just not worth doing to me, i'll get it. I don't want to switch to a eletric water pump, so are their any other timing sets I can use that can survive the CC306? Thanks.

 

If you go with the Cloyes, you'll have to install an elec. W/P.

 

LT4 HD is one of your only options if you retain the stock waterpump. Ill be keeping mine when I install a cam so I think we're stuck.

 

dayum, im trying to price out the cloyes and EWP and see if its cheaper than the lt4 ED, if so, i'll get that.

 

you can save a couple bucks by going with cmotorsports ex-187 double roller instead of the cloyes double roller.

 

Just found my answer:

Jeg part numbers:


220-9-3145
171-6351

203 shipped, the pump is on sale.

 

I used the lunati replacement, haven't had any problems yet...(knocks on wood)

 

Why do I need EWP with a Cloyes true roller? Does the Cloyes not turn the waterpump gear?

 

Im using this lunati from summit without problems. Its only $110.

Cloyes makes the LT-4 ED for GM.Get it from Symmett and save a bunch of money.If you are going to run the factory water pump don't get the one with the oversize crank gear.Get the one to GM spect.

 

odd ball question, but my buddy is thinkin of just buying a new stock timing chain for his heads/cam(306). I'm sure it will work, but how long do u think it will last. I told him to just get the LT4 deal now but I was curious.
