Since I started you on this wild goose chase, I'll speak up.
I have heard of people on this forum using a 2.5 starter on a 2.8. I also figured that the 3.4 TDC block was essentially the same as the 2.8 in this regard. They were all kind of based on similar castings. That's where my statement came from. I apologize for the confusion.
