I live near Oxford England and have just bought a (tired) '79 Cheyenne 350 4x4. Ok, so the body's a bit thin in places, shes only running on 7, 'park' doesn't work on the tranny but all this is a challenge for the months (years?) to come! Glad I found the site for support and inspiration. To start with, what pressures should I be running the road-pattern 31/1050/15 tires at ? Theres no stickers on the car and the Chilton manual dosent list any. 2./ The manual states that the plugs should be R45TS- I assume these are Delco which we dont get here- is there a Bosch or Champion equivalent? 3/ There is a lot of valve gear noise - I assume the lifters are hydraulic- are they easy to change in situ (this may be contributing to my misfire!! I'll be starting off with a compression check this weekend) Thanx for any help, Kind regards Andrew Newman Hopefully my Bowtie will soon have a strong ' heartbeat in the UK'
