Rebuilding my top end (after incident I'd rather not talk about). I ruined one of my con rods, but have a set of slightly older ones. These have the brass small end bushings, while the originals do not, and are machined alloy at the small end. Is there any reason not to use the older ones? Thanks for any input!

There will be other more informed than I but I have a 66 T100SC engine that came to me with later non bushed rods and even a roller bearing on the drive side so it would seem that there is a lot of interchangeability in these engines that could be possible. It also has the later oil pump and later cams as well so I would assume that it saw some serious duty in it's past. As I said, there will be more knowledgeable people that will chime in.

Cheers, Wilf

I was waiting for John Healy to provide the definitive answer, but until then I'll offer my humble opinion... I have three different C series rods in my possession. They range from relatively slender to very sturdy, but keeping in mind that the early engines were tuned hard and finished, and won, a lot of races, including endurance events, I wouldn't worry about using any of them in a road engine. I'd use the older ones DV, unless they've been used for racing, are bent or oval, cracked etc.

Vetterdog, if it were my engine then it would be getting new rods.

Thanks for the feedback fellas. The rods I have came from a good running motor, and I will be just buzzing around county roads, no hard running, those days are behind me. As I just got a replacement crankshaft in the mail today, I'm going to begin building this motor again. (Nobody local grinds cranks anymore!)
