Which Cam?

[jderry]

im sorry john i didnt see your question. get new shaft and new gear. sorry man

The LT4 timing kit comes with the gear, but where can I buy just the shaft and bearing?

I have a shop press so pressing it isn't the problem.

Got my oil system all squared away.

I was wondering if anyone knows how to replace the water pump drive gear?

very nice!

I'm having trouble getting the oil pump drive installed.

The stock one pops right in. The new gear on the stock one works.

The billet piece will not fit into the hole..

Spent a little while with some emery cloth and got it to fit pretty well.

Timing set came today, got that installed.
Now I'm waiting on my water pump seal installer so I can install that.

Glad to hear it's going well for the most part. I didn't have any problems with mine slipping in, but then again by the time I installed the billet piece my stock gear was getting all tore up from the cam.

So heres something weird.


Look at this link

Says #1 is top dead center at 9 o'clock.

Looks wrong to me, I am pretty sure it should be 3 o'clock for 1 & 6 right?

it should look like this. if you look you will see a casting ridge on the hub and directly above that will be a short casting ridge like in the picture. line those up while at TDC



then you alighn the arrow on the balancer at the 12 o-clock also.

I think he's talking about the cam's dowl pin. But yes it is supposed to be 9 o'clock:

lol my bad. in that case brian is right. also if you have the dowel style opti you will notice a sleight key way groove to help you line everything.

[jderry]

Yeah, I figured that out, I have it TDC for #6, I figured the dots on the cam & crank gears would be #1.


Thanks for the help.

What would be a good idle for my tune?

[meissen]

I think mine is like 750-800
