had to let the gts go...

well, struck a deal today for a brown/tan vinyl 74-5 swinger, saw the receipt from the original sale, written in pencil, 8 miles and 4/10th's! sold to a lady who meticulously maintained it for 27 years! /6, 3rd owner. 104xxx miles, has rust below the back window in the flat panel between the window and the trunk. speckled rust in trunk pan, 3 or four small holes. has a/c and a big ol' smog pump, but not one crack in the dash, no dents, original hubcaps, highback bech/bucket seat, all for 1300, that is a great deal, currently registered, clear title, etc. I am stoked, can't complain about that at all. runs great, it's clean, I think its a great place to start! Now, here's the big question.... since I'm gonna yank the /6 a little later, should I just build a 440 or go with the stroker I was gonna build? I can get a 1977 440 motor complete from an imperial with a 727 for 190 bucks, it has been in the rain since last summer, but a good machinist will clean all that up I'm sure, and I'd end up with about the same power and torque for alot less than if I try to build a 408, I bet. 440 parts are dime a dozen on craigslist, etc. and for a boulevard bomber weight is not such a big deal, to me, hell, Mr. Norm did it, right? I'd bet that there is not much weight difference between a 383 and a 440, but will the 727 fit? the dart has a 904 right now, I think. I could put heavier springs in front, fat torsion bars. Bigger radiator? I know the motor swap kits are similaly priced, from /6 to la or /6 to rb would be about the same, so why not? I would't have to jump so far off the hook to get really good, streetable power, high reliability, and tire fryin' torque!!! I'd have to similarly upgrade the rear end, pay about the same for tti's, with just a mild rebuild, and intake swap, ignition will be the same price either way, msd, ignitor, etc. so what are the draw backs?? what do you think guys?
