/6 to 360 swap
I just did this swap in a 72 Demon. The Schumacher conversion mounts fit perfectly and the 360/904 lined up nicely. I got my motor/trans from a 76 Cordoba. I needed a Lokar trans kickdown cable to replace the cordoba kickdown. The slant 6 kickdown is totally different, and the cordoba kickdown hit the firewall. The Lokar solved it nicely. I'm using an Airgap intake, so I also got an adjustable throttle bracket, which the Lokar mounts up to very nicely. I got the Lokar and the bracket from
www.magnumhp.com. With a little loop, the slant 6 throttle cable works fine.
You can use the existing wiring harness, but you'll need to extend the positive coil wire. I used an electronic ignition kit from proform, and a new could from advance auto.
Also, I used Hedman ceramic headers, and they fit perfectly with no bending/banging required. I would suggest leaving the exh studs off the motor for ease of installation. When I dropped the motor in, I tied the headers up in the engine bay then dropped the motor in from the top.
I replaced the full size starter with a mini starter from Advance auto for a 1991 Dodge Dakota truck with a 318 motor. I removed the plastic piece which extended the terminals on it to expose the "regular" terminals. It fit in with just a little wiggling AFTER the motor and headers were fully installed. First I ordered a mini starter from summitt, but the terminal setup was modular, and did not have the terminals I needed. I did not see a way to modify it.
I used the pulleys that came on the 76 'doba motor. It had a smog pump and A/C, neither of which was reinstalled. I bought repop alternator bracket and P/S bracket from an ebay vendor. Since I was going from A/C to non ac, I had to use some washers as spacers between the water pump housing and the brackets to get the belts lined up. I then measured and bought belts at Advance auto. If you are not changing from A/C to non A/C, or don't have s smog pump, you can probably skip this.
One last thing, if you have PS and are using a /6 k frame, you will need to notch the k frame so the ps pump can rotate for tightening. The line coming out the back of the pump will hit the point of the k frame and prevent you from tightening that belt. I have not yet ground that off, but will tomorrow. Don't worry about this one...it'll be obvious when you install the p/s pump...no advance planning required.
Let me know if you have any quetions or problems...it's fresh on my mind as I just did this a week ago.
