A couple of pix from my vortec 4200 inline six engine swap into my '51 GMC..
http://profile.imageshack.us/user/efi_diy/The engine fits its a bit tight on the PS pump and alt. Bang for the $ its hard to beat these engines - ebay has listing for engines that are under 30,000 miles for less than $1000. Its really hard to rebuild a 250/292 for that price.
Its not a bolt in though and does need fabrication - the end result is a truck that gets >25 MPG and goes like a raped ape.
