If it's a Shelby, it would have to be a K-code. If it's a K-code, it might have a serial number stamped on the block (from what I gather, about 1/2 of them did). If it has a serial number (K followed by 6 letter VIN), it's a K-code block, and a chance it is a Shelby modified motor. If no serial number, it might still be but harder to prove. Check the year in the casting number. If it's not 65-67 (68?), it's not a Shelby motor. The K-code motors had screw-in rocker studs. You could pull the valve cover and see. If not, it's not a K-code and not a Shelby. If it's a factory reproduction engine, all bets are off, and it's probably not going to bring 'Shelby money'.
Given that K-codes are very rare, and a Shelby extremely rare, it's not likely you have one, but stranger things have turned up in barns, garage sales, etc. But everybody and their brother has a '289 HiPo' or 'Shelby' motor sitting in their barn ('cause it has a 'Cobra' air filter on it).

The intake is wrong for a true shelby - it is a modern part. From the picture it looks like a dressed up 302. A running 302 is worth $300 but unless it has a lot of name-brand hi-perf parts in it and paperwork showing it was balanced then it is only worth what someone will pay. Performance engines rarely bring prices that equal the cost of the parts installed.
