New set of K1 4340 H-beam Big block Mopar connecting rods

7.000 length 2.200 rod journal .990 pin ARP2000 bolts (stock mopar width).

These rods allow offset grinding your stock 440 crank rod journals to increase stroke from 3.750 to 3.925 inches

The rods with increase stroke yield the following performance benefits.

1) Increase displacement of 20 cubic inches
2) Reduction in rotating weight (weight off crank journals/bearings plus light weight rod big end)
3) Improved rod/stroke ratio
4) Reduction in reciprocating weight (small end of rod plus lower compression height piston plus light .990 pin)
5) reduce rod bearing speeds

$585 plus shipping (I've had these several years and would likely be more than double this price today)

thanks
