Well, if there's ONE good thing about being an all too commonly broke TDer,I see a lot of forethought going on, keep it up!
it's that we have the extra time to think things through properly. :thumb:
Ab-SOL-utely having them balanced."And, rods will be Eagle H beams(SRT-4 rods, #CRS5945D3)
These rods will be "off" length-wise upon receipt for the 2.2,
but the machine shop will correct this.
The pin hole will require re-sizing for the larger pins.
So my machinist will bore the hole off center by the .0004"(yes, that's ten-thousandths) difference to correct, and meet spec. "
Of course you are then going to have those rods balanced?
I was surprised how much difference there was in a 'matched set' of T2 rods. The factory weight differential per rod is not very good. Chris Chadwich of NHRA dragster fame told me that 440 Mopar engines are really bad and he didn't expect my matched set to be near as bad as it was....and unfortunately I can't remember how many grams off it was...but we are talking more than a gram here. He had them balanced down to 1/1000 of a gram and one of them took a lot of shaving, it was a LOT heavier than the other three.
The pics attached are of the rods in the GLHS that I just sold being balanced. You can see the current weight more clearly displayed in the second picture.
I figure it this way; The engine I'm building was pushed close to its limits in the 1980s at 175HP!!!
If I'm going up to(and beyond) 3 times that, ALL PRECAUTIONS POSSIBLE are mandatory.
Good times Steve; Good times. :brows:
