Hello all,

I am new to this site and to membership in any car group for that matter. I have been playing with cars for some 43 years and most of that time with fords because I liked to be different and most of my early friends had chevys. I decided to join this site because I finally need some wisdom from you guys that have worked with the high performance FE motors. I have done a lot with small blocks but not a lot with FE's. About 20 years ago i bought a '67 Shelby GT500 in class 1 condition and have only put 15,000 miles on it since then. I have recently decided to sell it and wanted to freshen up the motor for the prospective new owner. I knew it had a 427 sideoiler in it but had been told some things about the internals that when I took it apart I discovered were not true. It was running pretty good save a little smoke from the number 8 cylinder which cleared after about five or ten minutes of running. I figured i was going to be in for a top end rework but was going to totally disassemble the engine just to know what I had. I found out I was runnng 60 over pistons and that the clearance on the rod bearings was close to .004 with plastigage. My question for all of you is: I have read it is not a smart thing to run a 427 with any more than .030 overbore, why if the wall thickness is still over .100? I have had the walls sonic checked and found nothing below that. What do these engines do when overbored? I have heard that they overheat, but this one did not run over 180 whether I ran it on the highway(4500rpm at 55) or in stop and go when cruising. I admit I did not drive it very far at any one time, but at least an hour or so each time. Any comments would be appreciated.

Jeff

Fords for fun!
