Oliver BBC vs BBF rod?

Noticed on the website they sell these with the same basic dimensions. Has anyone had experience to know the differences?

The BBF rods are 'on center'.......the bbc rods have an offset from the pin end to the crank end.

Enough to make piston choice an issue?

The BBC dimension connecting rod's offset may or may not effect the rod/piston relation at the piston's pin boss. The BBC application can be ordered with an offset (as known to BBC application) which will allow for the rod's beam to be centered with the rod's ends. This may offer better positioning (locating center) of the rod/piston pin boss relation.

Did you basically just say the same thing, but a paragraph longer?

So in visual the chevy rod has more material on the big end of the rods. Right?

Didn't even occur to me...gotcha.

No, no reason for extra weight

The big end is the same width.

There have been a train load of the bbc style rods used in bbf stroker engines for years but, if I was going to invest that kind of $s in a rod I'd get the most correct rod I could being that the cost is the same .

My thought also, perfect.

Lem explains the two applications (BBF/BBC). I offer an opinion.

No. If you read without prejudice you will understand Lem offers a description of a common part. I offer an option to that common part.

After Lem has done an excellent job of describing the BBC application and offering sound advise of part selection, one's thoughts should be perfected!

Not perfect but close,
Dave.

Ok, since we're practically on page 2 by derailing the thread into a sarcastic long-winded quote fest....you're right. I now see after I cleared myself of all my pesky reading prejudices. You are telling me, I could just get a 'BBC' rod with the factory offset taken out. Wait, did I just reiterate what you said, only in about 40 fewer words? Probably not......but it sounds good to me.

It is astonishing to me after Lem"s through detailing of the BBC rod, the most common rod incorporated in BBF engine builds, it often remains confusing to some people! Reiterate, no. The offset appearance is not a "factory offset", it is appropriate to the BBC application. Now if you center the beam of an aftermarket BBC application rod, it now becomes offset as to the rod's original application. Now, I have added over 40 additional words, offered no sarcasm and once again offered a simple explanation to a part that is often misunderstood. Not prejudicial, only offering what little knowledge I have of the internal combustion engine.

Your right Dave, I didn't realize life could be so rewarding! Raising a granddaughter and becoming (at least trying) an Internet know it all.

Have we got to page 2 yet?
Dave.

I'm not astonished at all. Ok, you're right.

bump for another thread derailment......

Dave gives good long answers but,he's not a boring Novelist like someone from Calif.
