I have an ’86 FORD 460 in a e350 van, with 68,000 miles. It hasn’t been running right so we decided to check it out. Carb is off, pulled all the plugs, stripped all the pollution junk! Ran a compression check on all the cylinders, here is the results:
Cyl 1 130 NA
Cyl 2 129 NA
Cyl 3 120 140
Cyl 4 138 140
Cyl 5 135 NA
Cyl 6 135 NA
Cyl 7 135 142
Cyl 8 130 142
Are these numbers OK???
I’m assuming that part of the reason for the low numbers is the fact it has an 86 cam and cam gear set, retarded timing I think. Not planning on hopping it up, just would like it to run good….
All the plugs looked OK. Pulled a valve cover and there is not any buildup on the rockers, motor is pretty clean for being 25 years old….
What is the pipe that’s runs together from the back of each head, can it just be plugged???
Might pull the cam gear off and put a ’69 on it…
Thinking I will be able to pull about 5K(flat bed with a race car) with this if it starts running right.
Any other suggestions???
