Long Rod Kits
Have features that offer advantages for performance and durability that surpass standard short rod kits. The advantages are:

A lighter piston, shorter compression height
Lighter pins (.990 vs. 1.093)
Lighter connecting rods (BB Chevy vs. BB Chrysler)
Less wear on the cylinders, the piston stays higher up in the bore putting less stress on the thrust side and on stroke motors pistons speed increases and a lighter bobweight helps to reduce wear.
Better dwell time at TDC and BDC for tuning.
Easier to balance without extra heavy metal.
Less total reciprocation weight, saves on harmonics, crank and bearing wear.

Note!
1976 to 1978 400 blocks max bore .020

Engine Info
413 Block standard bore 4.180
