Thoughts on a 225 rebuild

You obviously have no clue who Charlie is, I can tell. He's been racing slants longer than a lot of people have been alive. Trust me, he knows everything you're sayin and probably knew it before you did. He certainly knew it before I.

First, longer rods have zero effect on torque. Say it with me. Zero. However, a longer crank throw (stroke) would. All longer rods "do" is allow the piston to dwell at TDC a little longer and "supposedly", "possibly" increase the power stroke a little. It's a difference you'd never feel in your butt and likely not see on the dyno.....at least on a slant six.

All that said, it has been proven that shorter rods are actually better on the street, because they keep piston speed up at TDC thereby helping to fill the cylinders faster. This isn't secret information, it's all verifiable online in many, many different places. Even after all that said, once again, we're splittin hairs talkin about a street slant six. Were we talking about a mega cube stroker big block used for racing, it might be different, but we're not.

Also, the other "benefit" is the reduction of friction on the cylinder walls and piston skirts due to the reduced angle on the rods by being longer. But again, with the slight difference we're talking about, it's splitting hairs at best on a slant six street engine. Again, see my reference above to the mega cube stroker big block that we are not talking about. lol
