  1. +George Withrow There's no comparison between the purpose a dragster engine is designed for and that of a car made for transportation. A top fuel dragster engine is designed to last for a minute and then is torn down. A car engine is designed to last 100-200k miles.

  2. +Mia Cassinelli I think "hemi" is a trademarked term by Chrysler. The design is not the same, but they use that term to sell muscle cars. The advantage of the "hemi" design is that the valves were oriented transversely, so you had straighter flow in the intake and exhaust. In a traditional v8 the valves are all in a row. That also means that more fuel mixture just goes right out the exhaust. So a hemi engine got shit gas mileage.

  3. Most engines aren't hemis because a wedge shaped combustion chamber causes the the fuel mixture to mix better and burn more efficiently.
