I assume my stock 250 has cast 5.7" rods? My research indicates they will hold unless I start pushing more than 6500rpm, which I don't see happening.

Thanks for all the help,

Not sure if you can get a wider lobe center?
I would go to a 116, but a 114 will work fine.

Stock rods are forged, it's not a Pontiac 350 V-8. = cast rods sick laugh

Normally I would turn to 6000-6500 RPMs on stock rods, with the Paxton super charger combo, it would have power up to 7500 RPM's.

Note: My stock rods were side grinded, polished shot peened & checked for cracks. Resized big end & ARP rod bolts installed.

Never blew up a stock Chevy 250 rod, they work pretty good.
