Re: Engine talk

Just to clarify, the 3.7 does not have direct injection does it?
And
Doesnt the 3.7 have an aluminum block opposed to previous engines?

I thought the 05-09 was the start of the aluminum block. Any year below that wasnt because it was kinda primitive. That's just what I've heard around from a few older guys. I noticed on GT models and the new v6 the heads are bigger from looks.

The easy answer is that the more power and more efficiently the power is created and transferred from chemical energy to mechanical energy via the transmission makes the difference. Obviously, the explanation of how and why starts to get fuzzier

Higher compression ratio engines, fuel delivery, more flexibility in timing, lighter parts, more gears in the transmission, etc. all make a difference. I just kinda miss the days when learning basic mechanical skills would essentially allow you to service your own car. Now, without a computer, all you can do is guess and be pretty sure.

Exactly. I know experience how to take apart and put a older carburetor engine. But one it hit fuel infection I didn't know jack. But with the technology comes more fun and power
