327 option

[STL_66 Chevy]

ok guys!
i have been going back and forth on which motor to run in my 66. today i came across a guy who is selling a rebuilt 327 turnkey motor with a 2 yr warranty and only 100 miles on it . he is also throwing in a brand new 350 trans (3yr warranty), headers, radiator and a bunch of other odds and ends not listed. all this for 3000.00 shipped to my door.
what are you opinions on this deal! i currently have a 283 that needs rebuilt and a turbo 400 trans also needs an overhaul. through my research i can get a new 350 for the price of rebuilding my 283... seems like pretty good deal to me but im not a motor guy! let me know what you guys think.
