Is the buick service manual a good source for rebuild info on this engine?

And is there a source for the correct pistons, gaskets etc. for this?

you can get parts for your 340 from www.kanter.com (http://www.kanter.com) or www.greenbaypartsworld.com, (http://www.greenbaypartsworld.com,) you might also try www.jcwhitney.com (http://www.jcwhitney.com) - after all they do seem to sponsor the site!Another site I haven't tried for a while is www.buickfarm.com. (http://www.buickfarm.com.)
But don't expect to pay 350 Chevy prices, 'cos it won't happen! Best of luck, Malc

Thanks for the reply.

Someone just gave me this car. Its been sitting in a field for about 6-8 years. It has a manual transmission with the shift on the tree with a 2 barrel carb.

I have not pulled the engine yet but I am trying to pull together as much technical info as I can on this engine and heads, valve train etc... before I do very much. I am trying to decide if it is worth the trouble.

I am also wondering what parts (if any) will fit on this engine from other gm engines.

Some of the performance things I am thinking about include: a little longer stroke if I can find the right crank, some valve work and porting on the heads, a little hotter cam would be nice, headers, electronic ignition, 4 barrel holley carb., automatic tranny....

So what does anyone think? This engine worth some or all of the above? Could I get some decent horses out of the 340? (assuming the block is sound enough to begin with of course).

Or would I be better off stuffing a big block in there? When I say "better" I mean more horses for the buck.
