Jeep 5.7L vs 4.7L

I am sure that this question has been brought up many many times before, but im new so ill ask anyway. I am wondering which jeep is faster from a dead start a 4.7 or a 5.7 I have seen videos of the 4.7 just blowing the Hemis out of the water, which dosent make sense to me considering that the 5.7 has a bigger engine. Are their modifications that can be made to the Hemi to make it so its just as fast as the 4.7, or are the videos i have seen just misleading? Thanks in advance!!!!

Re: 5.7L vs 4.7L

That doesnt sound right at all. The 5.7 blows a stock 4.7 out of the water.

Re: 5.7L vs 4.7L

I had a 2004 GC Freedom, this vehicle had a 4.7 HO with 3.73 gearing, I now have a 2006 Hemi GC Limited. I have obviously driven both extensively and IMO it does feel like the 4.7 HO was quicker till about 30-40 MPH, after that the 4.7 HO does not stand a chance against the HEMI. I would love to see a HEMI GC with the 3.73 gearing that would be impressive I bet.

The 5.7L is faster

Re: Jeep 5.7L vs 4.7L

After racing my sisters 2000 GC 4.7L and my dad's 2003 GC 4.7L i can say that the 5.7L 2011 GC is a little faster. It was a close race, usually under a car length but the hemi took it each time. I have to admit, i did lose to my brothers 1998 GC 5.9L. Still haven't lived that one down. My guess would be the 4.7L's were modified.

Re: 5.7L vs 4.7L

In my opinion my 5.7 is slow. I would hate to see how a 4.7 or a 3.7 would run. To my jeeps defence, it is the heaviest vehicle I have owned.

Re: 5.7L vs 4.7L

I read somewhere that the 4.7 WJ's are around the same quickness to 60 as the Hemi Wk's. But then again I don't believe everything I read online.

Re: Jeep 5.7L vs 4.7L

Were either of the 4.7 engines of the high output (HO) variety?

I've had both. The 5.7 is faster. Not by a ton but faster none the less.
