I am hoping some of you guys might be able to offer some guidance for me on a /6 to big block swap into a 1970 Swinger. I have a restoration project going with my 16 YO son, we pulled a 1970 dart Swinger out of the woods last year and have replaced the floor pans and are slowly working our way out from there. Lots of stuff left to do, but we are starting to think more on exactly what we want for a power train in this thing. Son wants a stick shift and since it was originally a 198 with 3 on the tree, it has the pedals installed. We have a 3 speed floor shift tranny, but haven't yet cut holes in the floor to accept this unit and I have some general questions I need to answer before we go too far. Being a cheap ass SOB, we are looking at using a 413 from a 65 chrysler 300 that I just happen to have sitting around. Now the car is /6 all the way and I expect the 7 1/4 and everything associated with it will need to go no matter what else we do. I have a 8 3/4 from the same Chrysler 300 with 4:10 gears which we think is our budget route to correct the rear end issues, just shorten and install. We expect to mount the springs inward from stock for the extra clearance in the wheel wells. I also have a 23 spline out of a 70 E body, but think that may be difficult to use in the A body. I also expect to have to install disc brakes up front to stop this baby. I also assume any horsepower will require sub-frame connections to keep it from becoming a pretzel.
Questions are as follows: 1) - Is it irrational to stick this 413 into this little car? 2) - Opinions on using the 3 speed transmission, good, bad ugly or indifferent? 3) - Do our thoughts regarding shortening the C body rear end to use in our A body make sense? Appears to be best cost approach at this point. 4) - Assuming the 413 is a viable idea, it has a stock cast intake, should I plan on replacing this and do you have recommendations for a replacement manifold/carb combo? 5) - Is there anything here which I should be aware of and haven't thought of that will bite me you know where later?
I have been I well treated by the members here and think I may save myself some headaches here by asking before dong, something on the order of measure twice, cut once if you know what I mean. Please if you have any thoughts, comments, suggestions or even derogatory remarks I have thick skin and would love to hear from you guys that have been there and done that. Thanks in advance for your support.
