Here Come the Funny Cars by Irwin Stambler. about 1973 I would say. I don’t have book handy to look at. Funny cars are also called “floppers” as the whole body flips up to expose engine and drivers seat. I love books about race cars. I once passed up several kids books like this at a library sale (they were from the 1970s also) and have regretted it ever since. So now, anytime I find books like this I pick them up.
