Thanks for the advice! I have a '70 Cobra Torino. I am the 3rd owner. The 2nd owner blew up the Cobra motor back in the early 80's. he replaced it w/a 351, which he blew up. This is a non-cobra 429. motor was sitting in car when I got it. just sitting, not bolted down, no trans, etc... basket case. I got it up and running, drove it a bit. It has now been sitting for 4-5 yrs. just getting back to it. it is non adjustable valve train, replace push rods to adjust. I am taking it slow on the motor now, starting w/ lightening up the valve train. that's the plan, the mechanics work hasn't started yet!
Thanks for the advice!
