[Fot] Chevy rods/Moldex crank

[Larry Young]

Do all V8 rods have no chamfer where the two rods meet? I think someone 
told me the modular Ford rods were not made this way. If so, they would 
be a better choice if a custom crank is used. When I did Chevy rods, we 
narrowed the journal on a stock crank by running a bead of weld along 
the edges. The only problem was getting it straight after the welding. -

Now have switched to a custom crank sized for these rods. Motor can spin to 7000 no problem. Someone else mentioned the availability of the clevite bearings which is awesome.

Now the custom crank was made with these in mind so they are no longer piston guided. Since they are for a v8, there is some machine work involved in cutting a radius on one side of the big end so it won’t foul the radius of the big journal on the crank. Pretty easy for a good machine shop. You’ll likely find that you need to chamfer the rod bearings as well
