The Poncho 421 SD's had forged rods from the factory.
1963 era approx.?
That's why when my friend would want to go to Pontiac race days1/4 mile) I would say OK, but let me find my catchers glove, he would ask why a catchers glove, I would say so I can catch some rods flying out of the blocks!!!!
What a shame on so many nice Ponchos had cast rods.
IIRC, SD 455 & 455 HO's had forged rods.
