They will in fact work.  I have hundreds of hours on Chevy rods.  The only thing is that you have to order custom rods.  My machinist, a  master
Chevy race motor builder, put me on to the specs and the rest is history.  Love the Clevite bearing, super high quality and available in + or - .001 sizes already coated.

This topic has come up several times.  I have a fair number of friends who own speed shops and are great high performance engine builders.  The consensus among all of them is to not do this unless you have a crank made with narrower journals to create a big end to journal side clearance of no more that .006”.  The idea with this and why all manufactures use close side clearance is to create a healthy dose of oil spray onto the cylinders, pistons and cam shaft.  If you use the chevy rod on a standard Triumph journal you have a side clearance of over .100” and all the spray just directs horizontally which does not help a thing.  I have yet to find any engine spec that lists anything over .010” in all my 70+ years.

My opinion and I’m sticking to it!

Hi, Could anybody tell me what rods you are using on a Moldex crank that is sized for a Chevy rod.  This is for a TR3/4 engine.  Pat number, size or application would help.   Thanks in advance.   Lorne
