Top 10 U.S. Hot Rod Engines: #3 & #2Chris Breeden posted in Custom & Hot Rod Life6 days ago1.2KComments (17)RepostBumps(16)Comments (17)RepostBumps(16)A completely objective look at engines & Hot Rodding in the U.S. of A.!Recap: #10 Oldsmobile Rocket, #9 Buick Nailhead, #8 Buick, Oldsmobile & Pontiac 455, #7 Buick, Oldsmobile & Pontiac 350, #6 Mopar Hemi, #5 Small Block Ford, #4 Big Block Chevrolet. Let's look at the #3 & #2 picks!#3Coming in at number 3 is the GM LS engine. That's right just when you thought the pushrod V8 had gone as far as it could be taken, along comes the LS. By '97 the Chevy Small Block was 42 years old & everyone was looking for the next thing. In '55 when Chevy released their 1st OHV V8 the technology wasn't new. They simply put the engine together in a better way. When GM was designing the LS series they took the same approach and put together a better pushrod OHV engine. The result was the LS series of 4.8L, 5.3L, 5.7L, 6.0L, 6.2L & 7L engines. As rugged and as adaptable as its predecessor the LS series has proven to be the future of Hot Rodding & will insure its place well into the 21st century. Anything that had a SBC in it can have a LS in it. The beauty is that it will weigh about 100 pounds less. With the possibility of digital operation in a Hot Rod the future couldn't look better! #2#2 Before the Flathead Ford V8, speeds were impressive, but crossing that 100 MPH barrier was reserved for only the most expensive autos in the world. Ford ended that problem. With this 90 degree Flathead V8 speed was reachable to almost anyone! Despite Henry Ford's insistence that the only car Ford ever needed to make was the Model T, FoMoCo would introduce the Model A in '28 & '32 introduced another new body design along with a Flathead V8 engine option.The revolution of speed that resulted would come to define autos in the U.S. right up to today. The automotive aftermarket was born out of the pursuit of speed that came with the Flat Head Ford. It arrived in '32 & production stopped in '53. The Flathead has never left Hot Rodding. Despite it's heavy weight, low HP potential & build expense it is still loved by Rodders. Wherever you go, if Hot Rods are there, its a good bet one probably has a Flathead between the frame rails!
