My machine shop recomends not going with the Eagle SIR 5.7" rods because of the clearancing that will be required to clear the cam, he says go with a shorter stock 400 rod and it clears with no modifications.

The Eagle rods are most likely better material, but after you grind a big chunk out of the cap/bolt is it still better?

Also what is the length of the 400 rod vs the 5.7" 350 rod?

Is thrust side loading an issue with the more sever rod inclination angle or are things still decent with the 400 style rod?
