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
You know normally Im not one to really care much for originality on these cars but I'm with Rob on this one, this car needs a 100% stock restoration. These days E-bodies are worth more when they keep their slant sixes vs v8 swapping them. I'm not sure about what modifying the slant would do to the value but I wouldnt do it.

And theres no chance in hell you're gonna get 250-300 hp out of a naturally aspirated slant with good street manners.
