Cam/Crank TDC question
Since the weather is getting warmer, time to start working on the Monte Carlo. Last season ended with the motor being in the car, but not being to start. She would backfire through the intake. Then she had to go into storage.
Now she's back out and getting cleaned up and now I can start working on it again. Was told the valves are probably too tight. Distrib was good and played with various timing, all with no luck real luck. Back fire did change from going out the exhaust to coming up through the intake.
My question is, when I was looking at pics of when I assembled the engine, I had the crank at TDC, and the cam looks like I had it at the 12 o'clock position. Looking at pics, people have the cam at 6. When I was doing the valve adjustment, the intake/exhaust lifters all move properly and at the right time. I did the test with the air coming out of cyl 1 spark plug and it blows plenty of air out.
So should I second guess myself or does that sound right? Thanks
