Raw metal TTIs ??
I don't know.Mine came coated.But I can tell you this I paid $750.00 for mine.I wanted to use a mini starter right.So I checked my instructions and the called TTI to make sure I got the right starter.I ordered the Mopar starter that I was supposed to use.Guess what my headers would NOT fit.THE ONLY STARTER THAT WILL FIT CORRECTLY WITHOUT BEATING ON THE HEADERS WAS A STOCK STARTER!!! I was not to happy.I have a 383 I dont know if a 440 is any better it may be a better fit with a RB block.
