TKO Swap on a budget

[NvrDun71]

I realize Budget and TKO conversion don't belong in the same sentence, but what is the cheapest and effective way of approaching an auto to TKO swap for my 71' Nova. Is a kit form the most cost effective way to go about this or does some research and careful planning and part selection allow it to be done for less?

The car will have a 400-425 horse small block and Ideally I would like to run the tko600 as it would be the perfect pairing for my 3.55 geared rearend. At the end of the day tho the initial purchase price for eveything is a bit hard to swallow. Any advice? What route did you guys go for your conversions? Just trying to figure out where I can cut costs and what I can't afford to skimp on for the complete swap. Any advice is appreciated.
