CSX 2299 is not a 427. 427s start with chassis number CSX 3XXX. Your car was the second Daytona Coupe completed. I have the Monogram Viking Blue #21 CSX 2299. While we encourage period liveries and allow fantasy liveries, there is no need to repaint your car. Besides, I think the 65 Guardsman Blue car looks better. My #21 has a 3D printed chassis and a thin, sheet aluminum interior, with thin-cast resin dash, console, driver, and spare tire/wheel. I have flat sheet plastic interiors in other TT cars, with dash top and driver head and shoulders that look fine and are easy to do. I would think that the front motor would be very difficult to make competitive.
CSX 2299, after an impressive list of drivers in period, was sold to Michael Shoen in 1969 for $5100. Mike Shoen wrote The Cobra-Ferrari Wars.
Looking forward to seeing your car. I plan on being at HQ on Saturday and bring my six TT cars to test.
