I don't know if I should say "Little" because they produce the same HP as the 3rd gen Hemis did.
Which leads me to the question how do newer single cab 4.7s stack up against 3rd gen single cab Hemis? I have always kind of wondered who would win?
I had a RCSB 05 Sport 4x4 with 3.92/LSD and with only a borla cat back on it. It was stupid fast. No truck should ever be able to go that fast. It was downright scary to drive sometimes because of how badly it handled. If you hit 1/4 throttle through pretty much any turn, you were sideways. Pavement, ice, water, didnt matter the road surface, you were sideways.
My 09 4.7 is ALMOST as fast (maybe a little faster actually), but doesnt feel anywhere near as dangerous. I truly believe this as to do with the suspension enhancements made to the rear end. Going from leaf springs to a 4-link coil setup did WONDERS for how this truck handles its power. Willing to bet the 4th gen Hemi's are even better.

Indeed. This was the primary reason I was OK with the 4.7. Its not the gutless 235hp motor it was 5 years ago.
