The little 318 & Racer Brown's quality products

You aren't wrong, I haven't found concrete evidence either but I've talked to well over 50 Mopar people that have stated it made the engine run harder. Have even set aside my Mopar bias and talked with Pontiac guys as well because their pistons have the offset as well. They stated the same thing, made the engine run harder.


Here is something to think about.

I run domed pistons. How do I flip them around?

To that end, I have never seen an actual racing piston that has an offset pin. That’s the only way I can see you could accomplish what you are doing with a domed piston.

I have purchased pistons from about everyone in the industry and I asked them all if I should get the pin offset and every one of them said why? You’d be the only one doing it.

Are there some ultra high engines that do that? Probably. But if they are it’s F1 type stuff and they have test equipment to determine if it works.

Guys with an *** dyno are just guys with an *** dyno.

And I’m not disparaging you in any way. If you want to flip your pistons by all means do it. It absolutely positively will do no harm or damage.

And if it makes you feel better do not let anyone talk you out of it. You have to trust your gut and go with it.

Not a thing wrong with going with your gut.
