Hello!

I was wondering if such a rod was ever manufactured by Ma Mopar:

a 6.86" length HEMI rod

with a small end for a 1,09" wrist pin.

NASCAR rod maybe???

If I remember correctly KB made an aluminum rod that size.

Yes. The early 64-65 race hemis had that rod. The 1.03 pin didn't begin until the street Hemi in 66.

And was that rod bronze bushed or not?

Would that rod be just the same forging as a street hemi rod? Just that it wasnt bronze bushed?

Yes, very early 426 Hemi, pressed pin.

GOTCHA.

So I guess if you just take some 66-71 street hemi rods and drive out the bronze bushings and resize the small end to press fit a 1.09 wrist pin, you would basically have a 64/65 HEMI rod?
Sre they the same forging? Or are the press fit rods any beefier on the small end?

I'm not sure what the small end size would be if you took the bushing out. I can't imagine why anybody would do such a thing. I have seen the old press fit rods but I didn't pay any attention to them. Whatever you're thinking, forget about it. Floating in bronze is better than pressed in steel.

The 1964 rod had a foot width of 3.72 inch if you have a street rod to compare with. I-section was 0.35 sq inch, max rpm 7000.

Did the NASCAR rods have the 1.09" pin? Those big heavy suckers with the 1/2" rod bolts.
