I have some extra strong 5/16 SS pins that lejralie sold me. Let me know if you want some, I will send them out ASAP. Mine haven't broke.
You will be fine driving it for that short of a distance if you don't have the cog belt on and you don't get on it. Don't you have a deep impact socket for that crank bolt? That and a 1/2 ratchet will do the trick to get it snugged up.

Yea, I can do it with a ratchet, I just need the extension for the size I'm using...
I'll go to SEARS tomorrow to get one...
Jeremy, how much for those pins?
I'll also look to see if they have any 250ftlb TQ wrenches.......
I just want to get it tight enough to be able to drive to where it needs to go....10-15 miles, I don't plaon on driving it for a while, weather has gotten bad around here, so I'm in no hurry...
I'll be going into Sikoras for some work on the setup sometime in mid april...

I Pmed you Jeremy.......
Thanks a lot.....
Do you think that the pins broke off inside the pulley, or did they fall out, I can't really see into it, and I don't want to take the crank bolt off.....

Put it up on some ramps and shimmy under there and look behind the LS1 crank pulley to see if the pins are there or half there. If they broke off inside the crank cog, its not a problem just drive them out with a metal punch and drive the new ones in.
I got some logging done today without the cog belt on. The knock retard was pretty bad with the cog belt on from take offs and stopping. Without the belt on, the KR was non existant from stop and go take offs. I got a max of 1.8deg of KR that was because my idle was surging pretty bad when I stopped and took off. When the idle was smooth it didn't register.
FWIW

Sounds like a killer project. So you only read 9 pages huh, There is another post of mine that went to 20+ pages of my personal hell with two sets of these things
With the ATI dampner you will be set. The crank cog won't spin like ours MIGHT under high loads due to how its held to the stock LS1 pulley.
If this thread is dead by the time you get to yours, post up I would like to know how things are going with that 408
Another area that might be a problem is with the knock sensors on our cars being so sensitive and how these cogs like to make some pretty good vibrations in the ol engine compartment. I will get some good logging done tomorrow. I will be watching how my KR is without the cog belt on. With it on I was picking up some serious KR from stopping or taking off at a light and between shifts. At WOT it wasn't as bad, though I was seeing a high of 4 deg KR which is probably due to my hypersensitive 98 knock sensors. Damn 98's
Glad to see you post up Mark, don't be a stranger....misery loves company....j/k...or am I?

Sorry for the delayed response..been out of town on business. Thanks for the warm welcome to your Misery. I will try not to be a stranger but I will not be on the board as much as you guys (60 hours a week and 3 kids in activities will do that).
I will post when mine starts to come together. I will have the advantage of assembling everthing onto the block outside the car. The only thing I will not be able to simulate will be the inlet hat to radiator proximity. That looks as if it could present a small problem...any suggestions? Anyway how do you plug pics into the posts?
As to the set-up it's a 72 or 73 tooth crank pulley and a 31 tooth supercharger pulley using 960 belts.

Bos, I think I found a LS1 balancer that will fit our pins on our crank cogs
I just emailed them to see if they have an non underdriven one. I also think Speed inc. carries this brand too. Maybe you can run your crank cog over there to see if the 3 pins fit into the 3 holes that are in this balancer. It is also keyed too. This would be great if they fit, the crank cog would stay put no matter what.
Whatcha Think?

Sup Kyle, saw your pics of that iron block beast sitting in your bird, it looks awesome.
It's made by Powerbond/Romac? New Era Performance has em listed for 199.99
If they made them in a non underdriven application it would be perfect that and if the crank cog pins fit into those three holes around the hub of that balancer.
I have an extra crank cog here so if anyone has access to one of these let me know and I will send it to you to see if it fits.

Sounds good man............. Still waiting on head studs so hopefully this coming weekend ill have it all back togeather waiting on my stock tank to get back from being sumped and my 60#ers will be here too.
The cogs are all thats left for me so hopefully it will all be figured out by the time i place my order around May 1st or so.

Jeremy look at what Tom did w/his COG setup in his post, he cleared out the space in the bracket and he is running the belt under the tensioner fine.......
This could be the answer, I asked him for specific measurements.......

Looks like I'll be getting the steel bracket, I just don't feel comfortable grinding up that high with this cheesy aluminum bracket.
But DAMN things are looking good now.

who's tom??
on a related note, i saw a crank pulley for a whipple charger for a chevy truck, instead of pins, they have large ....fins / tabs / winglets ( you get the idea) that fit in between the posts of the stock pulley. they are so big that they fit snug between the posts.
i wish i had a camera to snap some pics. i don't know if anyone has pics of one of them or knows someone who does.
