What are you starting with? 170 (six) 3 speed, 4 lug rear end?? To change over for the V8, you will need the whole front suspension if possible: springs, spindles, brakes (5 lug). I'm unsure how this will bolt up. I installed a mustang II front end in my 63. You will also need to change the rearend, if your making any kind of horsepower. An 8 inch from a mustang will work. The C4 tranny will bolt up to a 289/302, but I'm not sure about the tranny mount. This might have to be fabricated. I know some people stay with the stock 6 cyl front end and still run a v8, but the stock 6cyl springs are not made to handle the extra weight of a v8. Plus handling will suffer. What are your plans? Do you want 350 horse or just a cruiser? just asking.
