Trying to build power....225 step by step help

Its 1 of 482...dont forget its a 225 3 speed manual , , deputy challenger...i just bought the shell with some few parts , needs a total resto , my cuda is a 2 tag car , 340 4 speed , in my book the 225 challenger is not worth more than 30k for a 60k resto , i have 30k in the cuda and its 70% finished, but this base model challenger will unfortunately never be really valuable if its restored back to stock..i just wanna have fun with it and put it back on the road
