come on guys, lets not be so negative. There is nothing wrong with that galen doc, they come in gray paper. My 67 hemi documentation from him, looks like that, about the same date, around 2003.
Its a nice 383 convert with docs. If you guys know more about window stickers, I could see maybe I am missing something there, but that looks ok to me.

I would only take shots at the hemi conversion, whether that is true or not. I find it odd, that they added undercoating to a california car (why?)
but the headers look real and probably could be hard to replicate.
and it makes sense it would need a rear valence change as california cars would not have the valence with exhaust cutouts. and after they do the conversion, it become illegal when it hits the street. hum...
I think the hemi would want to mate to a hemi spline? the 383 4spd would not be a hemi trans. Only 440 and hemi cars got the hemi trans.
then the K frame issue, as mentioned.

Seller is confused no doubt on the R/T factor, never made an R/T in 71 in a convert. If that seller had some better info on where that documentation came from on the conversion, he could have something unique. But there needs to be more.

I have to wonder, if the value of the 383 would offset all the added costs of putting in the hemi, like the brake booster offset, and maybe heavy duty springs, etc. The dealer would still retain that original engine.
Someone should know how much those mopar headers would go for, that would be the first thing I would check to see if that was a reasonable price, that seems high. the hood would have to be date code correct, etc.
