listen to swifster... car is worth a lot more with the original engine than with a $10,000 race motor.... so keep the 265, wrap it up so its weather proofed and keep it safe... and get yourself a toy to put in the car til that day you decide to sell it..... might even be nice if you end up with time to rebuild that 265 while it sits, use a heavey assembling grease when you put it together, no oil at all in it.... and it can sit forever as long as your bag it and seal it well
