Its really too bad that more wasn't done with this engine. No real aftermarket, never put in cars, etc. In my quest for a quick, cool-sounding and extremely efficient V8 for my 70 Challenger i want to daily drive i kept coming back to this one. Its small, its light and being a DOHC it will sound wicked with some dedicated pipes, make very good power and kill anything else in efficiency.




because the 5.7 is lighter, physically smaller, more efficient (with MDS), more powerful AND cheaper to manufacture....

sounds like you need a 5.7 in your chally. my '11 charger is a beast power wise (published times are ~13.7 in the quarter, ~5.2 0-60, in a 4250lb car) while getting 22-23mpg in mixed driving over the 8k miles I've had the car...



I dont think the hemi is more efficient... as a design. With the MDS sure... but i've always thought that was a really stupid idea. Its a cop-out. Rather than actually design a truly modern and efficient engine, they just find ways to use less gas in an inefficient engine? Why not just build a better engine? Ford did. Its just hokey from start to finish i think. I dont want a V8 in my car that becomes a 6 or 4cyl... i want a V8! With a better design i CAN have my cake and eat it too.

Just my opinion. Not a fan.

If they made (and i'm sure you wont hear this coming from anyone else...) a smaller hemi... say around 5.0L... then maybe (though still without the MDS). But sheer size has its drawbacks, and in MY case i just dont need a big engine. The car is light. A 318 could be fast in this car... Hence my recent obsession with the Ford mod engine.
