chevyslayer or66F100466, does the PA spacer PA68509 fit into the the crank pilot on a 460? I have a similar engine set up in my 55 ford, and would love to do this swap!I'm running a 6r80 behind my 521 in my 1970 torino. I'm using the 1/2 inch converter spacers with the stock 3.5 ecoboost converter no problem so far. Iv driven this combo for about 100 miles, at first the shifts are really harsh but once you get some miles on it things really smooth out. Shift are smooth on low throttle, but drop the the hammer and she will chirp 1-3. Downshift are quick and precise. Well worth the investment.
Awesome, cant wait for the pics, and thanks for the info and pics shared so far!The converter bolt patterns are the same size. My converter adapter kit was suppose to be here Wednesday but never showed should be here today. I’ll take pictures of everything as I’m mounting the trans. I’m going to run a stand alone cooler. There is a lot of aftermarket manifolds out there to adapt to the 8an
