Timing

I logged my hours from the very beginning. They include time on the couch reading the manual, watching videos and studying photos.

Everyone's timing will be different based on experience, selected options, and any help you can get.

Ultima estimates 400 hrs (only 350 hrs if you purchase the pre-fit option).

I ended up around 440 hrs. This included extra options such as spraying underbody with Raptor, installing sound deadening and insulation, installing a stereo/speakers/subwoofers, installing a backup camera, and a few other items. Additionally, the 350 hr estimate is most likely for a naturally aspirated engine whereas I installed a supercharged LT4 with a dry sump. The S/C engines and dry sumps require a lot more plumbing.

Since "completing" the car, I have around 100 additional hours of tuning and making modifications. This includes tasks such as additional AIM programming, catch can overhaul, a new Billet Specialties supercharger lid, custom painted Motion Raceworks Valve Covers, relocated the coil packs, front brake ducts tubing/mounting, and re-sanding/painting the door edges.
