The best Ford engine to use in the Casey Luna kit will be Windsor based engine. The Cleveland engines don't fit at all well. Its been said that the chassis in these kits were two scale inches,that 2mm in 1/24,too narrow. I agree with that having built six of these kits. Thats the main reason the Cleveland engines don't fit well. The Casey Luna cars also ran with chives from time to time. The model pictured though should have the ford in it.
