7afe rebild VS silver top swap? Options

[addictions]

I have been debating on rather or not to have Doc-tweak do a 3s swap or a 4agze but he brought to my attention that a silver top would be way cheaper and all i am looking for is a little more get up and go but not still have 25+ mpg (this is a DD car) and i do alot of traveling all over the place but would it be better to just rebuild the 7afe to run like new or swap in a silver top? i have been looking a silver tops for a few days now and have seen them sell for $800 it will cost me around $1000 to rebuild the 7afe like new so whats the better deal for my application? so please let me have your .02 (ill give it back i swear!)
