Thread: Z7 Install help

Ordered the shorter dog bones and poly engine mounts, will have to see how these work outs in regards to clearences. Any suggestions on where I should get a Monte Brake Booster? What year Monte am I looking for if mine is an 01 GP GT? Part #?

Got the shorter dog bones and poly bushings for everything, doesn't vibrate too, too much, but definitely more noticeable than stock. The engine does not move at all! Rev it and it stays put, and the shorter dog bones made plenty of room for the down pipe, no more issues with the brake booster.
Now for the bad news, had a problem with the manual boost controller, can not get it to adjust the boost at all? It is stuck at 15psi? No matter what I adjust it too, stays at 15psi so I am totally baffled?!?! Hooking it up is pretty straight forward, just can't figure it out? But now for the really bad news! Took the car out for a couple passes, car seemed to drive ok. Took it a little easy because the Tranny was already a little weak and didn't want to destroy it. Got the car up to about 40, got on it a little, car made boost then back fired. Eased off and then got back on it again thinking it was cold made a loud bang, car was dead! Wouldn't start, thinking that the time chain let loose? Hopefully the valves didn't take a hit???? If it was the chain, guys have any suggestions if I should just go stock or replace it with something different? If I destroyed a cam or valves and head need work, any suggestion for that as well? Too much invested in the car at this point to walk away from it. Want to keep it a daily driver, so I don't want anything too radical.

Yeah, I hear ya, I was not looking at putting 15 lbs of boost into it first time out. I was hoping to run anywhere between and 6 to 9 lbs of boost, but since the manual boost controller was not working correctly we took it out anyways. Whats done is done and I have too much invested in the car to walk away. Installed a boost gauge so I can see the vacuum and boost levels, car is in the shop across the river, will have to take a photo of the manual boost controller hook up and post it later. I'm more concerned on what broke in the engine. Hopefully its nothing major?!?!? Leaning towards the timing chain because it was a quick bang and the engine instantly cut out with no other noises, will update what I find as we tear into it.
Has anyone ever broke a timing chain before?

So as it turns out, the timing chain is in OK, but I stripped the teeth off the cam shaft gear? Only thing I can think of is the age and mileage on the engine and I guess that was the weakest part of the system. The cams are also damaged due to them rolling over after the gear went, not sure about the valves and pistons yet? Anyone know how stout these engines are? Is there a lot of room there where maybe they didn't get damaged? Since the cams have to be replaced, any suggestions on what I should replace them with? Was trying to keep the car a daily driver and get reasonable gas mileage, any suggestions would be appreciated.
