Don't know what your budget is...But I came across a Black/Tan 98 Cobra last fall, always had a woody for one and 98 was supposedly one of the best years for the 4V motor and if I was gonna upgrade to a Cobra, that was the year I was after....32k, one owner, pretty mint...asking 13.1. So I would bank on paying more for a 4V...
Was a sweet original ride...I took it out for a test run and wasn't really overly impressed with it...Nice car,no doubt about it...ran good, but you really had to wring it out to get it moving compared to a pushrod motor...
Then I popped the hood and that sold me...I didn't really feel comfortable going thru the learning curve of a 4V as I know jack about em...I like doing my own wrenching and know mine inside out, it's never been back to Ford since day one....
BTW...I think the TT was for Twin Turbo....can you say Yowza !!!!
