Finally get to pretend I am one of the cool kids - Holley kit swap
I don't know if you can still get them or not, but I originally did my Hemi swap with Schumacher mounts and a 4 speed with TTI headers. I really didn't have to touch any structure to make it work. The stock (well, I assume, who knows what they did to my car before) Z bar worked fine and the headers cleared. I'm still running the Milodon center sump pan as well. So it's about as close to a standard engine swap as you can get, which was sort of my goal originally as I don't have a lot of fab equipment or experience. Figured it was just an easy way to get a more modern engine with all the efficiencies that go with it instead of building up older tech to get there.
:lol:
I should have said that differently. Let me better explain.
The motor I am working with in the car is a core I am using as a mockup. The "good" motor (that is also a core) is on a stand and will get pulled down for a hone and rings assuming the rust in the bore doesn't require an overbore. Either way, I expect to have an extra motor laying around which has had me do some daydreaming about what I might do with it.
With a moderate build with just a 6.4 cam/intake and shorty headers, I could see the second motor being built up and a little spicier. Bottom level would be better heads and a bigger cam, upper level might be a forged shortblock, dual drilled heads and a HC FEAD so I could put a HC supercharger on it built in stages. Or maybe it sits in the corner and I buy a 6.4.
This daydreaming has me thinking about the overall build and the idea that potentially if I go a little bigger on the motor, I could see "rebuilding" it using different mounts and such to remove some of the compromises like the motor being forward and up and not having long tubes. So there is the additional potential that the Holley mounts and headers could end up in the same pile as the mild motor. This might mean no AC, or even bigger changes, but those questions get mulled over until much later.
Depending on how this build goes (thus the "if I like it" comment), I could see taking the first motor and the Holley parts and putting them in my '74 Duster 360. This is very much dependent on how much cutting is required and would not include the T56 and tunnel mods. The way the motor dropped in, I could see doing the swap and just adjusting some of the 4 speed parts like the mount, zee bar (or hydraulics) and building a shifter mount to maintain that location. But only if it is almost a bolt in. So my comment about "liking it" is less about the G3 and more about how well the swap goes in the end and if I want to jump through some of those hoops to put one in my '74.
Something to be clear about is that when the '73 hits the road with the G3/T56 I will have 2 running and driving A-Bodies with space to only really park one. The fact that one has the numbers matching LA and is a low production 4 speed car while the other is a go anywhere do anything more modern car means they can fulfill separate rolls for the most part. But if I swap a G3 into the '74 I would have 2 swapped cars and would really need to start thinking about getting rid of one. And it is on the periphery of my mind that once the '73 is on the road, I might not even want to keep the '74.
I have a lot of history with the '74 since I pulled it from the wrecking yard in '92. Makes it hard to think about parting with it.
