Starfire Rods:

These are the Con Rods used in the Starfire (4 Cylinder) Engine. These came exfactory in 2850 Engines. These came exfactory in all blue and black 3.3 Six Cylinder Engines. These Rods are favoured by Engine Builders

Popular Perception:

let me ask this, why are starfire rods more sort after for building worked 6s than standard rods if everything isd the same specs? End of submission by Weekendwarrior.

That is because, when Blue/Black 6's were relatively new, many more Starfire 4's were being wrecked than the 6's so most people only knew them as being in Starfires (but only because they'd never seen Blue/Black 6 rods). End of submission by Qute. 

Identifying Starfire Conrods:

pretty easy: red rods have 5/16" bolts, using a 7/16" socket to tighten the nut blue/black/starfire rods use 11/32" bolts and use a 1/2" socket for the nuts End of submission by Ben Simpson.

Interchangeability:

Starfire rods can be used in any red, blue or black six or in any Starfire Engine. Even though the stroke is longer in 202's and 3.3's, their pistons have the gudgeon pin 0.125" higher to prevent the piston colliding with the head and the piston descends 0.125" lower.

Clearance:

just got to watch the rod to camshaft clearance on a 202 stroke. it should clear by about 60 thou with a billet cam - factory 202 cams are clearanced here to clear even the red rods.
