What is the part number for the best double roller timing setup for the lt1 with the electric water pump and are there any thrust bearings or other components needed to make this change?
Thanks for the help guys!

 

Your options for timing sets depends on your year, more specifically, whether or not you are using a vented opti. If you have a vented opti, you can use the Coyles 3146 Double roller. You will have to remove the reluctor ring if you have a '96-'97 OBDII car and you have to use the '96-'97 crank hub (shorter). You have to use an EWP (but you have that already).
If you have a splined opti, I don't think you have much options then to convert to a vented opti and use the above.

 

I thought it was the Cloyes 9-3145. Isn't the 3146 for a non roller cam?

 

I think you are right on the part number. The 3146 set is for blocks with a raised cam. Both should work on roller cams though.

 

I think the bolt pattern is differnt on the 3146 (based on the pictures). It specifically says it does not fit LT1 (but that could be because of the lack of water pump gear teeth).

9-3145 is what most LT1 people run for a Cloyes double roller.

 

Thanks alot for the help guys.. This is in a 95 car with vented opti.

 

Then you can use the 9-3145 double roller but you will need to use the '96-'97 crank hub. Also be prepared to clearance the inside of your timing cover a little.

 

I am going with an SA Gear Double roller timing setup for roller cams PN (SA-78150) and Professional products SFI LT1 Damper with hub and woodruff key Do you think these will mesh properly? What is the difference between the hubs as far as from 95 to a 96-97?

 

93-95 hubs are longer than 96-97 hubs because there is no crank sensor. On 96-97s the reluctor for the crank sensor sits between the hub and the crank gear, taking up space. They shortened the hub to keep all the accessory pulleys aligned.

 

Yup, and usually when you go with a double roller like the cloyes 3145, the crank sprocket is just about as thick as the stock crank sprocket and the reluctor ring combined, so using the shorter OBD2 ('96-'97) keeps everything aligned correctly.

 

I am using the 3146. No problems here.

 

ok, so verufy if what i got will work on my 96 LT1

professional product LT1 balancer, with keyed hub

cloyes double roller 9-3145, and electric water pump

 

Will it bolt on, yes, will your belt line up perfectly, I don't know.

 

I'm using the Rollmaster billet double roller timing set with a clearenced 95 timing cover and I'm going with either the Jeg's sfi balancer or the Professional Products balancer.

 

Have you put it all together yet to see if its all going to mesh right or just in the process?
