63 spit engine swap

[lewis mckillop <lsmc@lightspeed.net>]

    hello all,
    I am thinking about changing the engine in my 63 spit. I would like
some information about other engines (and trannies) that will be the
easiest to slid in. I was told a rotory RX-7 works well and provides a
major increase in power. I am a little hesitant to go with the rotory
since i know exactly zero about them. Any ideas/thoughts on this would
be appreciated.
    thanks again,
