I’m getting ready to drop my 360 magnum motor that I had done up with a cam grind from bullit cams, new heads and added a carb style intake into my 70 satellite. Car is originally a slant six car auto. What will I need to drop this in? I’ll keep it a auto trans right now just to make it simple.
I kept the serpatine belt set up on the front of the motor.
I’m missing all the brackets for alt and power steering but I should be able to find easy.

Can I buy motor mounts that will work on the 6 k frame?
What’s style trans should I use? Any 727?
What converter?
How will I get the power steering to work?
What do I go with for alternator?

this sounds like alot of extra work and money ,plus fitment issues just to fit this engine in here. Myself ,I would find a 408 or 416 stroker

so it has been a while, but here are the things I ran into.
I put one in a 65 coronet, but it had a poly 318 not a slant 6.
schumaker makes conversion mounts for /6 to v8. but not sure how it handles 318 vs 360 mounts vs bb mounts you would have to check.

727 vs 904. I used the original 318 converter, so it was neutrally balalnced. b&m used to make a flex plate for the direct bolt in of a 5.9 to a 727 and it was balanced for it. The holes don't line up for a 904 and they didn't make one. BUT I read some people slotted a hole and it worked. never read further on it.

power steering- 2 things here. get a van bracket/pump. otherwise the truck one will put the cap under the battery tray. the van tucks it in closer to the engine.
for the hose, I found a hose shop near me. lots of them over town and had them customize the ends and length so I could bolt it up to the old power steering box to the new pump. Some have mentioned it might be too much pressure, but I haven't had any issues so far. been 10 years I guess now.

I used the original alt that came with the 5.9.
not sure on your car but mine has the single field voltage reg. I grounded one field wire and ran the other to the single field vr just like any other dual field vr and it works fine.

The alt bracket also includes the a/c mount and the idler wheel I think.
a/c mount is different between vans and trucks.
I found I needed to modify all that swaping between the van pump vs the truck pump to find a belt to give me better wrap.
I got one thet worked originally, but decided to find a better one.
by swapping the idler with a 5.7 hemi one, I was able to find a factory 5.9 belt that worked, that was for a different model.
not saying you can't get a van one to work, but it wasn't ideal routing to me.

Yup, me too.
It seems no one has addressed the K member yet.
I do believe you will need to swap it for a V-8 style.
The slant mounts are very different.

As mentioned, the Schumacher mounts allow use of the /6 K-member.

Member als499 sells a flex plate on Ebay that works with multiple bolt patterns @ crank & converter, neutral (internal) balance. External balance should be available from B&M and/or others like TCI & etc.

oh I forgot.
360 LA pan. but use the LA gaskets.
using magnum gaskets will let it leak out the front and back.
apparently there is a 1 piece la gasket now but I don't want to rip my motor out to try.

Thanks for all the great info. I’ll need an electric fuel pump as well as a electric fan. When I order a new engine harness from year one which one should I order. I’m pretty Sure I should order one for electronic ignition. I have a b&m flex plate, picked one of those up when I knew they were getting hard to find.

You also may want to upgrade your torsion bars to thicker ones as the slant six ones may ready to break as they are known to do.

Probably want to get the V8 (shorter) throttle cable too.

I put LA360 into my 70 Sport Satellite. But that car was original 318 car . . . however, drivers side motor mt bracket needs to be a 340 bracket. It is offset compared to the 318. Not sure if Schumaker has the conversion for slant 6 to small block with that . . .

My car had 904 with the 318. But I had a 727 that was rebuilt and had correct converter, so I went with that behind the 360.

I used the wiring harness for electronic ignition . . . however, I did lengthen the harness for the ignition module, and placed it under the battery.

As was mentioned, I would upgrade the t-bars to something larger. Make the car more enjoyable to drive in the long run. Also, if it does not have front sway bar, I would add that in . . .

Good luck with it !!!

So Schumacher does not make a kit for slant six to magnum. They told me I need to find a 318 k frame. I managed to find one on a parts car out back. It has the sway bar on it as well. It also has a 727 trans I can use and the larger torsion bars.

I really wish I would of used the v belt set up on my motor instead of keeping the serpentine belt. How hard would it be for to change this over? I’d love to run a mechanical fuel pump, correct fan, and correct style alt.

I’m thinking I’d have to cut the input shaft down

you have to unbolt the whole front end off the motor and replace it with the la stuff.
the timing chain cover forward has to be swapped out.
I would guess the link above also shows you can add the mechanical pump back in if you add the cam extension for the excentric.

honestly I prefer the serpentine belt, but to each their own.
I hated trying to find the matching belts for a/c.

I put a 360 Magnum in my '68 Slant 6 Barracuda using the Schumacher mounts. If you are not going to use the EFI, you are leaving out one of the best upgrades for using the Magnum. It's easy, but a bit expensive or harder and less money. It's so worth it.

The other trick to using the serpentine belt is to use a smaller battery and cut the tray. That's what I did. If you search my posts on A-Bodies only, you can find out a lot of other good tips I accumulated from the web for doing the swap.

You do need to retain the Magnum flex plate to use the EFI. I simply elongated one hole to allow it to bolt up to a 904 small block transmission.
