1968 Road Runner '383' vs. 1968 Chevelle 'SS 396'
A-Body
I saw many Chevy Big Block 396 2-Bolt Main Chevy engines come into my fathers Machine Shop.
It wasn't pretty.
* Spun Main Bearings
* Cooked or Snapped Connecting Rods
* Cracked Oil-Pump mounts.
* Snapped Pushrods and Broken Rocker-Arms
* Cracked Lifter Valleys
Most of them usually had a Crane 'Fireball' High-Lift Hydraulic Camshaft that was around .550" lift.
But, with 'stock' Valve Train.
