I wish I could get a copy of that issue. The one that I do have I happened upon it in the Advance Auto store, read it and subscribed to it in November and have not recieved it yet. Going to call them Wednesday  to see if it's on the way or not. On the Oliver 60 a little of both would be great but if I had to choose, torque would be the one to go with. I used to Race Oval track( Dirt) in the Mini Stock 4 cylinder class 10 years ago. I have built a few  Chev 4 cylinder's but you can get their parts over the counter. Wish it was that easy on the tractor but what fun would that be.  I'm new to the puller scene and all the local boys pull Farmall, Case,and Deere. Ask them something about building a motor and they look at you like you've lost your mind for asking. But you hear them talking and you know their tractors are not stock. On the 88 and 880 block. I was just looking at a motor on e-bay for and 880 and just wondered what the difference was. Too far away to buy. I live in Carson Va. just south of Richmond, not too many Oliver's in these parts. Taken me 3 year to find the 88 I have now and it was a mess, but she's coming along fine now. I had the head for the 88 redone, ported and bigger valves.I did get the cam for the 880 to put in my 88 after I have it ground.
