Same in every other way other than the needed removal of the side material and pressing in a nice bushing so the wrist pin floats in the small end of the rod..

Modify a SBC main girdle (just cut off the front section and the rest fits like it was designed for the 60degree engines)
and use some arp studs and you got a bottom end that will take 350+ hp all day long.



How do you narrow the SBC rods? I've seen it done by ID chucking the big end in a lathe, but always curious about other ideas.

Interesting tidbit about the SBC main girdle. It's pretty wild that the two engines use the same main bolt pattern.

Another interesting tidbit. I'd heard about screw in rocker studs, but not SBF rockers.

(there are a couple of oiling system mods that are game changers in the bottom end)
Especially the 2.8.

Maybe I should do one of those "how to Hotrod the 60* V6"
books you see on the more popular engines.

In any case I'm excited to get started

More than anything
I really enjoy projects like this.



I'm curious about the oiling modification.

Maybe you should publish a book.

I live for building, and what's important is that you build what you like.

I might even have one around, but the magic of modern technology makes that superfluous.

ARP makes rocker studs for conversion to SBC rockers. Then you can use narrow-body SBC rockers in your V6. It's a common mod, and fairly inexpensive. With the conversion studs, and some aftermarket springs and retainers, my 3.4 V6 valvetrain can handle up to .550" valve lift. No head machining necessary. It uses the same heads as the 2.8 V6.

Putting SBC rods and valves in is nothing new and was covered in that book plus other guides.
But I agree that things like roller rockers and EFI etc. have made some progress.
