Hi All.
I have a 66’ mustang with a 289. The motor was built in the 80’s and put around 10,000 miles on motor before pulling motor out of car as it got in a accident. Motor has been sitting in garage since the 80’s till now and reinstalled into another 66’. I replaced carb with a new Edelbrock AVS2 and replaced distributor with a HEI distributor. Replace valve seals and other seals as well. Car hard to start. Idles at 1200 rpm. When put in gear idle drops to 380-420 rpm. Took compression and range from 105-115 psi. Checked valve adjustment again and push rods at TDC are loose again. So readjust valves and have 60psi in one cylnder now and push rod is loose again. Also performed vacuum test. At idle 16.5-18 with vacuum needle fluctuation and when car is put in gear vacuum drops to 15. Is it possible lifters have failed after sitting in motor since the 80’s not running till now? Or?.
Any input will be appreciated.
Thanks
