That is a beautiful car!
FYI-But same foundation is only if you squint really hard. Might both have an 010 casting 350 block but that is where the similarities start to fade. A 1972 LT1 is 9:1 compression (in '70 it was 11:1), 4 bolt mains, steel crank shaft, solid lifter engine. A 1972 Biscane 350 is 8.5:1 compression, 2 -bolt mains, Cast crank, hydraulic lifter engine. All those things interchange for the most part, but are much more heavy duty and/or performance oriented for the LT1. LT1 also had a bigger oil pan, windage tray, different timing chain, better connecting rods, and so forth than the low HP 350s that year.
