Im looking to do the same thing. I bought a 351 last summer, my 302 is tired and is in need of a rebuild with 132k on it. The 351 came out of a 94 Ford Lightning pickup truck. It has just over 100k on it. It has the tubular intake and i think some type of GT40 heads. I was planning on turning it into a 393, but i dont have that much cash to spend this year as i just rebuilt the engine in my truck. So i am thinking about dropping it in stock this spring so i can at least drag it. I hope it wouldnt cost more than 1k in extra parts to put the 351 in my car.
