Pretty sure he's talking the days before stroker cranks and 355's man. The 330's were an offset ground crank with chev or ford rod combo from memory. Lots of stock parts even more machining.Nah would've been a 355 crank in a 253.
Strokes are the same but bores are different but for some reason holden made the casting smaller around the bores on the 253.
If they left it the same the 253 would.be a champ
Thinning down rod big ends and bearings come to mind.
Small end bushing and Buick or Pontiac pistons.
They were a can of worms.
I think with an over bore they came out to a 333 or 334 or something.
