It can be done. Oil pan and front cover need to be swapped probably some other parts also.

Just rebuild what ya have the way it is suppose to be done and then you know what ya got . And if you do go with a rebuild BEFORE YOU just go out and BUY a kit look at the deck of the block for letters next to each hole as this will tell you what Bore class you have and by getting the sleeves that fit correctly for each hole will save you a ton of grief later . OF you can make a up grade to a 291 and have the block bored out to take the new larger sleeves and have them fit correctly and gain some extra pony power . But also keep in mind that if you want a gasser to live a long life then few things you MUST Do ( 1) You run low ash oil (2) you run nothing but 93 octane gas , You set the timing of that engine to the Spec's for the cubic inch of the engine as a 263 sets higher then a 291 .
