I am thinking of buying the Spirit 27T Super Kit. However, I have a few things that I am not sure of. I am not fond of the 10 bolt rear that comes with it. I am more inclined to use a Ford 9" but I see the Ford 8.8" is also an option so I may opt for that. My other concern comes with the quality of the parts included in the kit itself. I have been building muscle cars and classic cars for a while now and experience tells me that, usually, if it’s in a kit it is comprised of sub-par components to be as cheap as possible. That’s all fine and dandy until you shove a 500HP 429 Big Block Ford in the mix and all of a sudden the rad isn't large enough, frame can't take the stress, etc. I also will opt to use a Ford Transmission like a C6 rather than a TH350, not going to use the headers, won’t use the gauges. I am sure they can tailor the package to my liking but I suppose what I am trying to get at is, are the parts included in the kit worth the $10,000-$12,000 (plus shipping) price tag? Or am I better off sourcing the parts individually? I like the idea of getting most of my parts from one source but I am also not willing to sacrifice quality for convenience.
