have the motor apart. and i don't need the gears that run the mech. water pum since im going ewp? just wanted to see if i could get a heavier duty timing set without having to get the expensive lt1 timing kit since im not going to have the mech. water pump anymore? am i wrong?

So you want to get a heavy duty timing set, but you want to get one for cheaper than the stock timing set?

This is a very doable scenario. If he's using an electric water pump, he can use the Cloyes 3146 double roller, which is like $75.

Oh, good to know. For some reason Summit has two listed, one for 87 and the other for 119.

I sure can.

I edited my post, I meant which one besides the 3146, summit has two on there for some reason.

Pretty sure either one will fit. I know for a fact I'm using the 3146.

It notes that it won't fit the LT1 because of the water pump drive mechanism (this is obviously null and void when using an EWP).

Yeah I got that, but why the two part number and different prices.

cool. i knew there was an alternative since i was going ewp. since i was eliminating the mechanism, i wanted to see if anyone was able to put a double roller in there. thanks ramair and slp

Keep in mind that I'm fairly sure you're going to need the 95-style timing cover, as it offers extra clearance (not 100% sure though, you may be able to get away with the 96-style). The cover MAY need minor clearancing on the back side as well (mine did). But it was worth it.

Didn't know that. I thought that the only difference between the '95 and '96-'97 cover was the provision for the cps.

RamAir95TA

iTrader: (2)

Yes, the CPS is the only difference. But depending on how the bung looks on the other side (never seen it myself) for the sensor, it may interfere with the thicker chain. I know for a fact the 95 cover works, not so sure about the 96+.

on my 93 am i able to get a bigger timing set or does only the factory size work on mine? Sorry for hijacking but im about to order my timing set and figured it was related to this topic.

You are unfortunately limited to stock replacement, due to having the spline drive of the non-vented optispark.

Now that I can't say, but having looked at the inside of a couple of '97 covers, I don't see why his '96 cover would be any different from a '95, clearance wise that is.

that is what i figured. There arent any companies that offer a beefier one that will work im guessing?

The only difference that i see on the write up is that one says sold as a kit and the other says sold as a set. Other than that i dont see any difference

Hmm. Well the block that's being machined is a 95 lt1. Is there a CPS on 96 b body lt1's? ouch... I'm going to have to look at my car now lol

Just remembered...96+ use a reluctor ring to drive the CPS. This requires additional space on the crank snout, which is why the 96+ cars use a shorter length crank hub. He'll also need an OBDI-type crank hub.

The block isn't the issue, it's the timing cover/crank hub.
