True roller timing set My builder has requested I find him a true roller timing set, with at least 3 crank keyways for my LT1 385 build. Only problem is the local parts store is telling me there is no true roller timing set that's adjustable. What is everybody else running? This is my first build, and I keep running into problems!
Thanks,
Amanda

This is where you step in to tell your builder that there is no point in running an adjustable timing set with an LT1 where the ignition timing is controlled via the PCM (unless you are running a dizzy/carb setup). May I recommend the Cloyes 3145 double roller, if you are converting to an electric water pump?

To the OP
1. If your engine builder cannot figure out something as simple as this you
might want to shop elsewere
With that said
2. IF you are running a electric water pump. Get a Cloyes timing chain for a SBC with a factory roller cam. Then press the gear off of the water pump drive shaft (its the gear that normally runs off the back of the cam gear on a factory type setup). Then reinstall the shaft as you normally would. Everything should clear as I have never seen one hit but double check it first. This solves 2 problems at once as you now have a adjustable timing set to allow you to get your cam degreed in where you want it and it takes care of the hole in the timing cover without having to rig it up with a freeze plug and jb weld or some other combination to keep it from leaking.
If you are not running a electric water pump I would be suprised but if so I think the only choices are a regular replacement part or the LT4 setup but you wont be able to degree your cam in with them as they come you will have to modify them to use degree bushings. And with all that hastle to do that I think you will find it easier to switch to the electric pump.

If you are running an electric water pump here ya go. The one on the left is the correct timing chain set for the LT1.
Scoggin Dickey SDCS1090, nitraded, double roller. The one on the right, SDCS1040 is wrong.
