is this true about a 350 sbc vs a sbm

you forgot to highlight the bronze bushings in the small end of the 340/318 rods...stock 340 vs 350 of the same caliber no comparison...the 327's were awesome but lacked the cubic inches the chebbie 302 was an astounding engine but the rods .....well....they were chebbie rods.....jes sayin ;)
This is the best argument hands down, besides the shaft mount rockers. Top is the 340 rod, bottom is the 350 rod. Both stock castings. Remember, the 350 rod is 5.7" and the 340 rod is 6.123. Not to mention all the extra meat on the 340 rod.
