So here is where I am at with this build. I have pulled all the parts for the engine, but to my disappointment, the kit is molded in frets of color. Except for the pan (molded in black), the engine is molded in a metallic-ish silver. This normally wouldn't be a problem, but the pigments used make the plastic soft. The high pressure used to fill the molds cause the plastic settle in some thicker areas, and flash out in thinner areas. I really wanted to detail the engine with good colors and have sharp components, but that is not what you can do with this soft and flexible plastic. It doesn't sand that well and fitment of the parts are lacking.

(All the major components of the engine. The block has been filed, sanded, flash removed, and glued together.)
The block of the engine lack any kind of location pins to align the two halves, so you kind of have to use the front face of the motor to align it and glue from the back, allow to dry and then remove the front and finish gluing the block together.
Now I understand that Salvino JR are actually targeting race fans and first time model enthusiasts for their kits. That's why they mold them in clear, metallic, black, white, and the main body in the color base of the team with large portions of livery in decals so that fans can put together their favorite drivers cars without the need for paints, tools and modeling experience.
The drawback is that the molding is not as crisp and stable as it could be if the kit was molded completely in white with its clear parts and tires.
I really hate to say I'm disappointed in the kit, but the truth of the matter is the kit could be so much better. The body's of the car looks the part, but the thickness of it detracts from the detail it could have. The cowl flaps on the hood are there, but they are lined out over scale and even more so on the roof. At this scale, they really shouldn't been seen, it kills the aerodynamics that these cars work so hard to achieve.
Anyway, don't mean to sound like I'm bashing the kit, but I'm just disappointed as I had higher hopes for these Next Gen cars. They are what they are (hopefully just for now and soon to be greatly improved for model builders), so I will have to make do and focus the most effort on the body and livery to really make it look the part. I can only hope they clean up the kits like the older 2000s NASCAR kits from Revell. So anyway, the build continues and hope to have more updates over the weekend.
