Hello,Fire Bird Lovers ! I don't know a hole lot on Fire Bird frames,can a convertible frame handle & convert from a Strait 6 to a V8 400 to 455 -This is to also swamp tranny, and rear end gears & all other parts for a V8?." Please NOTE, I look for rollers-junkers when I clone or mod ! ". I want any 68 Fire Bird convertible to add to my collection." I prefer a 68' 400 HO -4 on the Floor ". But if I find one that ran & was the right price I would keep it stock and fix it up,but I am looking for a good deal,"Memory's R worth more than money !"
