Never had a 340... If I did have one I'd sell it... If someone would buy my block 318 I'd sell it to them... Assuming they needed something to tie to the end of a rope to keep their boat from going adrift while they were fishing... LOL..:poke:...
And your first line is a good one. IF a guy had a 340 and 1500, would he be better off to sell it for 1500, take the 3k and get a "free" 318 and build it ? He may very well go faster....
Obviously selling the 340 and buying a 360 would net the best bang for the buck... but for the sake of the thread... it's a 318.
