My bad. In that case, I completely agree with you.

If the 2014 v8 is really 6.2 seconds, then that is very impressive.

Back in those days, I had a stock 1970 Buick GSX Stage 1 Auto with A/C, power windows/locks etc. which was rated at 360hp and it always beat any stock 426 hemi from that era. Wish I kept it.

The real 426 Hemis ended in the late 50's...they changed to the wedges around then. Anybody who has a real 426 hemi is sitting on a block of gold.

There was no such thing as a 426 in the 50's. The 426 Hemi was the late 60's and very early 70's. Those are the ones worth a lot. The 392 was from the 50's and that is less desirable. And yes, a stage 1 455 Buick was a beast. It would walk away from a Hemi on the street. It made 510lbs. of torque. The Hemi was a case of too much flow for the street. It actually is quicker when it was switched to a single 4 bbl for the street.

Same amount of lead in right foot.
There are some commonly accepted correction factors that every now and then the more technical auto rags will note in their columns. Most also make multiple runs and some use multiple drivers to try to get consistent comparisons.

Nowadays you'd probably have to make sure both were at current flash levels since the 8 speed can make a difference--moreso on the engine with the narrower torque curve.

Sort of. There were still genuine hemis in the 60's, and they were not the same as the wedge heads. The wedge heads weren't slugs either, Daddy Don G. ran one.

I was always a Rat motor person, but it was a 466 cheater, so I couldn't drag with it.

If it makes you feel any better, Fiat [yes Fiat] had a hemi in 1907, 44 years before the '51 Mopar 331 ci hemi. Riley made them for Healey IIRC before Chrysler began with the military versions or their 6 banger versions.

Some purist historians would claim that only those very early units up till '58 were true hemi chambers, and a nitpicker would agree they are correct.

Tank and aircraft hemi engines excluded.

The later hemis aren't pure hemi chambers, but they aren't really wedge either, and marketing prefers the term and they are still much wider across the heads than pretty much anything else except a dohc special..

Exactly this. Love my jeep as a family car but this thing is boring to drive. V8 hemi is very disappointing for me. I have a 2012 GC altitude. I also drive a 335i which is probably why the jeep is boring to me.

I don't know what you guys expected from a 5200 lb SUV....but unless you get the HP up, the power/ weight ratio is just too high. Should have sprung for the SRT if it was performance you were after.

Don't know what kind of performance you expected in a 5200 lb SUV with about 360 HP, but didn't you read the specs....or test drive the vehicle? Maybe you should have sprung for the SRT. And I don't think there are any equivalent Euro SUVs, with the possible exception of the extremely pricey Range Rovers and Cayennes....Major expense there ; both purchase and maintenance.

Re: 2014 V8 is weak?

If you want to look at specs then a 5,750 lb Sequoia with only 21 hp more smokes your Hemi anytime. If you guys are happy with the hemi performance well more power to you but it doesn't mean everyone else has to agree with you.
