Hello all, ive had some mixed answers, i have a 1976 caprice engine that has been sitting for a while and finally got it back up and running, it took a new carb and intake manifold as the old one was cracked and its running better but i need it to be timed.
it has very low compression from what i see online 7.8.1 and I used a static timer to get the idle timed at 10 degrees but before i do the timing to 36 or what ever it should be ive been told that because im such low compression, and also due to my altitude ( 5700 above sea level ) that i need even more timing to 42 degrees instead of the typical 36-38. what are your thoughts? is more timing from higher altitude needed? and also more timing for low compression?
