Looking through some old magazines i've found engine swap articles on how to swap many different engines into old cars. Most popular were Olds or Cadillac engines onto a '40 Ford, Buick Nailhead into a '49-'53 Chevy (Car) and how to put a Chevy v8 into a '49-'54 Chevy Pickup. But what i don't recall seeing are a lot of articles that have Hot Rods with Pontiac engines in them. You would think with Mickey Thompson setting a land speed record of 406.6 in 1960 with one, and using them exclusively in his drag racing cars you would've seen a lot more swaps. I wonder why not, especially since they made really only one block., and could be bored from 287 to 455 ci. Was it size, cost, to hard to find speed parts that made them an unpopular swap?
