The Godzilla looks to be about the same width as a Coyote (~28") valve cover to valve cover, give or take an inch. Definitely can't wait to see it. I know Backdraft has shoe horned it in but not sure of the body dimension differences. It will look awesome!! To Mike's question, no, the Godzilla does not have a flat plane crank.

The Godzilla does not have a flat plane crank. It is a heavy-duty truck motor with 6 bolt mains. It supposedly is a couple of inches narrower than a Coyote and about the same length as a Windsor. Height is the challenge. I have estimated with the high clearance oil pan and the super short stacks, it will fit under the hood without a scoop. Nothing can go wrong lol.
I am doing hip PT like an animal so I can get back in my shop and see. Stay tuned.
Rickster, I am planning to run an oil cooler in the lower opening. That may require me to invent some sort of tow hook bracket. Maybe that hooks to the sway bar?

Ok....after 6 weeks of lameness due to total hip replacement I am back! Did you miss me? Now I have to figure out how to get that giant Godzilla engine in the car. First I need to do the clutch, bellhousing, and transmission install. My "beautiful assistant" magically knew I needed a ball bearing engine leveler and a dial indicator for Christmas. Now I have to take her to Florida for a couple of weeks...its 23 degrees here. I hope to have to engine ready to install when we get back. I plan to put the back wheels on the four post lift (As seen on IE 427) and raise it up with the engine hoist sliding under the front. What could possibly go wrong?lol
I decided I should get the Godzilla ready to go in the car so its ready when we get back from Florida. The problem with that plan is the engine in its stand was sitting very low to the ground and my newly replaced hip is not crazy about me getting down on the floor. To help with this I used my engine hoist to lift the engine up and put the engine stand on some 4x6s. In order to do this I had to remove the power steering pump and make a spreader bar so the engine leveler would not hit the injector stacks.

Next it was time to mount the Ram flywheel, but I realized I didn't have the bolts. I also realized I didn't have the bolts for bolting the Centerforce pressure plate to the flywheel or the bolts to attach the Tremec TKX to the Quicktime bellhousing. What bolts should I use? Here is the helpful tip. I went on X and asked Super Grok. That is Elon Musk's AI. It costs $150 a year but is so worth it. In about a minute, it searched all the manuals, instructions, forums, and catalogues in the world. It told me the exact size and rating of the bolts I needed. It even gave the exact part numbers for the Ram, Centerforce, Quicktime,and Tremec bolts I needed!1 (29).jpg
Once the proper bolts arrived I had no problem bolting up the flywheel and getting it torqued down. Next i needed to check the run out on the Quicktime bellhousing. I watched so many Youtube videos about how to do this that my "beautiful assistant" said "I think you are starting to have a THING about bellhousings". I took the plugs out of the engine so I could turn it over with a breaker bar on the front pulley. Then I had to get down on my knees, attach the magnetic dial indicator to the flywheel then get up, go to the front of the engine, turn it over a quater turn, then go back to the rear of the engine, get on my knees again and check the reading. Then get up move it a little more and get back down on my knees. I did this over and over and over. Every time the dial indicator would come loose from the flywheel and move so I would have to start over (after I put some money in the swear jar each time). I finally gave up

When I was home for lunch, I asked Grok the best way to attach the dial indicator. It said to take out four of the eight bolts, thereby leaving a flat area for the magnetic base to attach. I did that, and it worked the first time. After all of that and after checking numerous times my Quicktime bellhousing was just .00325 out. Well within the allowed .005 limit.1 (30).jpg1 (31).jpg1 (32).jpg
Now for the "Dumb Question of the Week". What are these things? I found two triangular things and one round spacer of some kind in a box marked Godzilla install kit. I suspect the round thing is for use with a stock style air intake but ?

Be sure and check the flange on that Quicktime bellhousing that it doesn't hang below the frame rails, you may need to trim some off. You don't want that to be your skidplate!

Good tip Mike. It looks like it sticks down the same amount as the Holly oil pan on the Godzilla, which would be an even worse skidplate.

Thanks Jim. I was leaning that way. i will check on that tomorrow and report back.
Jim, you are right! They are spacers for the engine mounts. There are no installation instructions for the Godzilla so I get to figure this stuff out as I go.

Ok update time. I managed to get the TKX transmission mounted to the engine using my super handy motorcycle lift and the engine hoist. It would be better if you have friends help with this part. Next I will install the Forte slave cyliinder and when we get back from Florida the engine goes in....hopefully. What could possibly go wrong?

Ok, we are back from Florida and done with all that blizzard nonsense. I am now getting serious about getting the Godzilla into the car. But first...
When I started this build thread, I said I would not try to show people how to build one of these cars. There are many threads like Edwardb's that do that better than I ever could. Instead, I said I would document my screw-ups so others could avoid them.
Here is one. I decided to install the pedals, MCs, brake lines, etc., while waiting for my engine to be delivered. I assumed, for some reason, that I would need a throttle cable for my stack system. I spent a week modifying the FFR gas pedal to accommodate my giant feet. When the engine came in, I realized it required a drive-by-wire throttle pedal like a Coyote. Ugh. I ordered one of those pedals, and now I am installing it. I also had to pull the MCs out because I had not properly adjusted them for side-to-side clearance. Since I was going to have to re-bleed the system anyway, I pulled out the reservoirs I had installed to give me more room for installing the Godzilla.
I found I have a couple of extra Willwood pedal pads, so my current plan is to use one for a dead pedal and one on the cut-off throttle. This will allow me to offset them and make more room for my Frankenstein feet. 1 (41).jpeg
Next up I will try to organize some friends to help and we will get then engine in. Stay tuned
I've never seen stacks with DBW, interesting. Any idea what is being used on the stacks for the actuator or whatever it's called?

Might just be the photo but it looks like that throttle pedal is in the same plane as the brake, or maybe even a little closer to the driver.
Neither is a good idea. You always want the throttle lower than the brake so that when applying the brakes you don't inadvertently also depress the throttle.

Mike,
Here is a picture of the actuator on the InnoV8 Stacks. I have no idea how it works but I guess we will find out. lol

Jeff,
The gas pedal is almost 3" further away than the brake pedal. I have not even tried to do any adjusting yet. I could put it lower but ...the giant size 15 feet thing again. I think I can move the brake pedal over some.

Today I did a dress rehearsal for the engine install. I plan to use the lift to raise the back end of the car, an idea I stole from i.e. 427. I will also use a power socket on the leveler. This is a very heavy engine so I will wait for next weekend when I can gather up some friends. With enough beer and a couple of crowbars we should get it done.

So....is the Godzilla a heavy motor? Yep.
Hoist tip.jpg
I used that hoist to install a lot of airplane motors. This is a whole different thing. I am glad the shipping frame was still bolted to the motor. Extending hoist legs waay out.

It should be fine now. I just had to extend the legs. I didnt even know they could go out that far. I have friends coming Sat to help me put it in. I need one fat guy to stand on the back of the hoist lol.
Today I test-fit the SS Godzilla headers from FFR. They are beautiful and fit perfectly. This may be the first and only set they have sold. Well done FFR.

How many guys does it take to install a Godzilla engine in a Cobra? Apparently, 6 and a half.

Thanks to my son Kyle, son-in-law Steve, friends Craig, Anthony, Shane, and my 8-year-old grandson James, we got it in! I ended up removing the reservoirs and fuel regulator, whose location I had guessed at before I had the motor. I think I can put them back.

Now on to hooking everything up.
Some people were concerned that the bellhousing or oil pan might hang down below the frame. I was very concerned about this too. I am happy to report that with that they are nicely above the frame. Phwew!
