THANKS again
Your '75 engine- even if an optional "high performance" engine- will have much the same- if not identical- internal parts as a base 350 SBC engine from the same years. The cam and possibly cylinder heads and intake may be different, and the performance engines mostly had 4-bolt mains, but for the most part the engines were much the same regardless of HP/TQ (large chamber "smog" heads, hydraulic cams, cast pistons and crank).

The sad truth is the early smog era engines were weak, power-wise, from the factory. But once rebuilt to performance specs, they're as good as any 2-piece rear main seal type engine.
