Winn - please don't stop posting that type of thinking as there is something in your post for everyone and I didn't know any of that. I did switch to a Mallory Unilite Dist and ended up using steel gasket.

Also it is my understanding the the older non-stretch bolts are better than the stretch ones. You just retighten them from time to time.

Karl,
I hope you went with a steel timing gear and upgraded chain. Also, don't forget to pack the oil pump gears with grease as this will help the pump start to suck up oil upon start up.
Thanks for the heads up on the indian head. I will try and find some around here.

I already have new bolts so will use those and just re-use the one for the bump bracket.

I haven't done anything with the timing gear... though I did notice it was vinyl teeth. I'll look into a replacement.

Without a doubt replace the timing set.

I have Rovers North as my go-to source for parts. Is there anywhere else I should be browsing or is what they have all I will need. Looked at the timing set they have and not too bad a price so I added that to my next order.

Thanks!

Also, is there a thread that may already address all the questions I have that I could be pointed to? I don't want to be too big a nag here!

The thermostat in the vehicle works so its' wired into somewhere not sure just yet.

Thanks,

I use it with an electric fan as my sensor to know when the engine is hot enough to trigger the fans...

Timing gear set for a 3.8 Buick will work, you can get them from Summit or Jeg's. Get the one that has multiple keyways, advance it 3 degrees, will give you lots more low end, from what I remember that's the only difference between the old cams and the 4.0/4.6 cams....

Winn,

How does the timing advance affect overall driving? This is the wife's D90 so it's more of a summer day driver and sees very little off road other than what I do on occasion which isn't much

I have a new gear and chain set coming but will run down to my parts store and compare it with a buick for reference and then I'll decide what I'm going to do.

Good idea. Did you remove the OEM fan and retro an electric in it's place or do you run 2 fans?

Well SHIT!!

So one of the mysteries I have of the head job is why they don't supply a new cylinder #1 lower head bolt (the one with the threaded top) when you order them? I went on the reuse it method as suggested and it snapped!

Now I ask: If the head bolts have done their 90 & 90 on a brand new gasket but never run... would you re-use those or just bite down and get a new gasket and bolts for a brand new torque?

Now I gotta go find that bolt...

Karl

All done!

Got the engine fired up first turns!! What a relief!! Thanks all for the info and tips. Got a last one. What is this chunk of steel? It hit me in the throat as I was dropping the exhaust from the manifolds. I think it was wedged between the frame and exhaust? Don't think it's even a part of the vehicle.

Thanks,

Karl

looks similar to a body mans dolly, it certainly is not a rover part, prior owner may have droped that thing and could never find, probably hoped/expected and thought it may have fallen on the road years ago.

Ouch, I hope your throat is ok! I agree with Carlos. Polish it up and keep it as a paper weight

A body mans dolly... I had to look that up and I'm convinced that's what it is as well!! I'm just happy it didn't clock me in the skull when it dropped. In a previous ownership this D saw some action. I noted that the front grill frame has been resprayed.

Thanks!!

Karl
