That would be an incredibly sweet base motor. Unfortunately, it's too tall and too long to fit in a Camaro.

 

Oh well, that would have rocked. I-6s are so much better than V-6s due to how well balanced they are and how much fewer parts they have. Looks like the 4200 is consistently named to Ward's 10 best engines:

Maybe it can happen somehow? 291hp and 277tq in its current form, bet it could be up to 310 and 290 by 2008.

 

So something like 300 hp OHV V6??? Ok that ain't the HV V6 we got now, 224 hp now with VVT and variable intake and DOD. So would this be a new generation OHV V6? Would the displacement possibly be larger?

As you can tell my intrest is certainly peaked!

 

HFV6.

 

Peak numbers (both power and torque) don't tell you much. A useable powerband is the key. Also, 1/4 mile times are more directly related to horsepower than torque. Torque is just a measure of the force output, and is changed by gearing. Horsepower is the measure of energy produced, which is not affected by gearing.

Yes, gearing will affect the 1/4 mile time, but only becuase it puts the engine in the range where it makes power.

If 1 car has higher horsepower, but the 2 cars have identical peak torques, identical weight, and the same traction, then the higher horsepower car will win.

 

I thought the GMT360's and the I6 are getting one mild refresh and then go out to pasture ... replaced by crossovers.

We spent 4 1/2 years with an I6 Envoy and simply don't feel the love you do. The LS2 in the TB SS on the other hand ...

 

I liked the power of the I6 in my mom's trailblazer, but over it was kinda blah. Especially when you consider the best milage we got (all highway) was about 20mpg. Just saw an ad for a Yukon with a v8 (can't remember which) that is rated at 21 highway. So, less hp/tq with the same mileage in a smaller vehicle.

 

My bone stock 100K plus L98 ran a best of 14.1 @ 98 with a 2.0 60' time. Then again it was also very cool out that night and wheel spin off the line was very minimal... Just a though.


Anyway, Either way a 5th Gen is going to be badass...
