is this true about a 350 sbc vs a sbm

Seems to me the object of your postion and the business to work for is to make money. (Not to argue the merits of various makes.) Many before you have smiled in the knowledge of the truth and taken the man's money (at the counter and on the track).

Thomas Tusser in Five Hundreth Pointes of Good Husbandrie, 1573:
A foole & his money,
be soone at debate:
which after with sorow,
repents him to late.

Figurative translation: A fool and his money are soon parted.
