You wanna bet? I have a REAL nice 72 340 intake. If I ever go to sell it, the damned bottom will drop outta the market for um and it will be worthless to everybody. Just sayin.
What Im saying is a cast iron 273 is worth $$ to a 273 #'s guy. Just like a cast iron 340 intake is worth $$ to a 340 #'s guy. Dont know much about 273's, but the LD340 is worth more than cast iron 340 intake all day long.
