Best E58 360HP Camshaft....your guesses

It has some misinformation in this article that he wrote for one the 72 motor did not get 1,92 intake valves. And as far as I know all 340s had a 750 thermoquad if they had a thermoquad.

1972 - The 340 four-barrel dropped to 240 horsepower:

• Compression dropped to 8.5:1; the compression height of the piston via wrist pin location changed by 0.10"
• The crankshaft was switched from forged to cast somewhere in the production cycle, believed to be in early April 1972, with engine 39118000 (thanks, Karl Thomas); a milder camshaft was used
• 340/360 were moved to "J" casting heads with 1.92" intake valves; exhaust valves remained the same
• Paint went from orange to corporate blue
