you know there are so many factors to why hes crank failed, like how much wear and tear are on it and so on, id say a reasonable number is 450, these are very good motors, but be careful with that nos :D
there is actually really not very big differences between the sc 300 and the sc 400, the only thing is really the motor and dravetrain blah blah you know? so i dont see why it wouldnt just fit right in there, because i believe everything on the frame and body are the same.
lol, well if you find out anything for sure, i got about a week or so to get all my parts together, you guys input will be greatly apprieciated :) thanks
good deal man, i got my sc400 for 4000 with 200k miles, and just about the same condition of the interior and i love it, i think we both got pretty good deals
