Finally get to pretend I am one of the cool kids - Holley kit swap

-
That looks like a good fit! I assume this is mockup. You could easily set up a port a power with the engine out of the way and gently push that inner fender out a tad away from that header, I bet. It wouldn't take much at all.

Yes, just a mock up with a core motor. Good idea on the port-a-power.
 
I'm not sure how much wiggle room the K actually has since the bolts have shoulders on them. Are the Holley engine mount bolt holes slotted? I wonder if the engine could be rotated a few degrees without the trans on it making this header really close.

Seems like there is some slop. I can look at the /6 k-frame when I get home.

Motor mounts are not slotted.

Worst case I will probably just push the inner fender in a little.

Remember, the shock tower is behind it, so don't get "real" carried away. You don't need much at all for a good gap.

You could shim the motor up just a tad... put a spacer between the block and the mount. You don't need much. Try experimenting with washers. Hopefully it doesn't throw the holes too far apart

I've got all kinds of shims, trying to clear this and that.. Mostly PS.. But I'm on biscuits

Nice work @DionR didn’t Holley give up on a lot of that swap stuff?

I guess some of the confusing parts on the Holley website is because of a different methodology than I would employ. Stuff that is generic and fits multiple years and models doesn’t show up using the filters. Other parts, like motor mounts are part of a kit in the filtering, but the motor mounts themselves aren’t listed unless you open the kit page and then they are shown (e.g. kit contains…with links).

So it seems they haven’t dropped anything, they just have to be searched out if you need them.

And the issues with headers is completely the EPA.

Looks like there is a fair amount of slop in the bolt holes. The shoulder on the bolt measured 0.746" and the hole in the k-frame measured 0.893". That's more than an 1/8" slop. The silver area in the below picture is the washer showing through the hole in the k-frame.

My plan is to use the TTI crank CL measurements and see where I am at and then put the car on a set of jack stands and see if I can loosen the bolts and shift it around depending on the measurements I get.

But I bet the mis-alignment in the holes take up a bunch of that slop.
 
do you have part numbers to the elusive Holley parts that are hard to find on there website?

please and thank you

I went to Holley's website and searched based on the model rather than "Engine swap parts". Seemed to work better. But here parts that the engine swap category doesn't show.

Oil pans:

302-60/302-60BK - non-VVT
302-61/302-61BK - VVT non-HC
302-64/303-64BK - Hellcat

Motor mounts only - BHS571

Crossmember only - BHS572

Headers - BH23104

Note that I had to search on the part number for the headers, they wouldn't show up in the model specific search. And they only work on '73 and '74 <<wink>>.

Cast manifolds - BHS582/BHS584

Fuel tank - 19-135

Fuel tank module - 12-319

PS hard line kit (Borgeson) - 198-231

Dipstick - 302-74

The dipstick had to be search by part number like the headers, but it does show it is in stock. Note that I haven't tried it yet and I have heard of reports that it is too tall and doesn't bolt to the valve cover like it should.

There are other parts they offer like a hoop for a NAG1, the adapters for the transmission crossmember based on which transmission you are running and transmission mounts. But they seem to be easy to find for now so I didn't list them.

Note that some stuff does seem to have been discontinued. And the NAG1 hoop is only available as a white box (unpainted) item so I wouldn't be surprised if that didn't go away. It seems like they offered everything both coated and uncoated but a lot of the uncoated stuff is now disco'ed, so I am guessing that anything they offer uncoated only is there only until that stock sells out.

Good point, very possible. Really makes me wish I paid better attention when I bolted the V8 one in.

I went and looked that old k-frame and it kind of looks like it could be shifted based on the witness marks the washers left. Time will tell.

I also grabbed a quick measurement of the crank CL and I am right at 1.125" offset from the DS, it is supposed to be 1.25". So I am 1/8" too close to the DS which (I think) matches the way it seemed the k-frame needed to go just based on alignment of the ends of the k-frame legs and the outside of the frame.

Guess we will see soon, it will be the next thing I mess with when I get back into the shop this week.

wow thank you for the list. I am torn on exhaust I have already purchased the cast 6.4 Cherokee manifolds that i have heard work on ABody swaps. (Golling Mopars in Roseville) part number 77072462AB. I am into these for $600. i do like the shorty headers they have.
