What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Exhaust manifold bolts?

Yes sir! All of them came out fine and the ARP bolts went in.

The front passenger side bolt on my exhaust is broken off below the manifold surface....

For future reference. This might be helpful with the exhaust manifold bolts.

That’s great for throttle but what about timing, afr, etc?

Debating on FI. Either way I can’t use the factory harness or computer. E38pcm does not do drive by cable.

Then you’ll need a dbc pcm. You need a computer to run the engine.

IDK, just wingin’ it. I’m sure you have it figured out. What are your plans? OEM or aftermarket?

To some degree yes but in my case I could feel the bolts flexing as I backed them out. The locktite was doing it's job and no amount of penetrating oil was helping. I did it with it as warm as I could stand to try and have soft Locktite. I was afraid working the bolts back and fourth could cause them to break or gall into the aluminum. I found that once I had them loose using my 3/8 air ratchet and just spinning them out worked the best. I got lucky and got all twelve out.

For the record his method is a solid method in most cases but there are some where it can fail.

finally, got my Belltech coilovers delivered. Knocking em out, now. New suspension, is a huge upgrade, when I drop this fully enhanced, rebuilt tranny and engine in.
Picked up all new tranny and fuel black braided lines this am. Maggy should be delivered next week. I'll be bale to add her, after I get back from vacay!
