Correct a 4.030 x 3.50 vs a 4.125 x 3.35 stroke engine. I know there are some guys running here in non wing with 360's I'm not sure how much they are winning. I contacted someone here that has both a 410 and a 360 and has said he's been beat more by 360's than 410's while running his 410. He's not the only one that has said that. Of course this isn't USAC national level racing. I even wondered how a -12 motor would do as those can been had reasonably, but you never know what your getting either.

The advances there now, are fairly slim because we have all been working on that since 1955. Chasis setups and the connection between the crotch and the brain of the driver play a much bigger part.

" the connection between the crotch and the brain of the driver play a much bigger part." !!! Not only funny but brilliant...

When I was younger, crotch ruled brain. Now its reversed.
Not sure which is better....
