Wow,
No one has problems or Ideas for several months?
Pontiac's Rule !, they never have problems,lol .

But for real,I need to ask any one(?), can a 1968 Fire bird convertible V6 be swamped out to a V8(400-455) , I need to know if there is any issues or any thing to do to the frame before dropping in a power plant?
The transplant would be parts from another Fire bird or Pontiac type !
I don't have the car as of yet, but this is for further down the road,....
Thanks to any one who can help(?),
