i recenetly replaced the timing chain on my 95 LT1 motor that i have in my 87 trans am.when i replaced it i just ligned up the marks and put it back together,but i didnt check to see if it was at top dead center.

From what i remember there are 2 rotations of the crank and only 1 of the cam correct?

im also hoping that i didnt do any valve damage turning the crank without turning the cam too...HELP would be great!

 

Did you make sure it was at TDC before you took the old chain off?

 

No,and that's the problem I think...I ligned the marks up after I took the chain off,which I now realize is what your NOT supposed to do

 

There is the problem. Timing is way off. Set to TDC and THEN align the timing marks on the sprockets. You should be good then.

 

Wow and now I feel real dumb,went out today to start tearing it all part again and found that my coil wire was unplugged.I plugged it in and it fired right up! Thanks for your help though.
