Interesting History lesson Thx! learn something everyday.

I, (with respects) Must add a bit more from My own research.

The 1.8k rpm max torque value (about 240 #ft) was the 'rated' output for the 2BBL base model.

However...
There were an total of 3 options built. 2BBL, 4BBL, and TURBO !!!...

Oldsmobile Jetfire, and Buick F85 were the turbo equipped variants.

With respects originalowner,

I humbly disagree with Your statement "it would require fab skills like Chip Foose".

LOL, in this Community that's a second cup of coffee.
