Everyone wants a hemi but a modern 3.6 drive train in a Valiant could outrun a 340. The problem is no one makes a "kit" to do this easly.
Who would like to see this???

No there's no kit and NOTHING bolts in. I have a TON of swap info in my build thread.

100% stock tune it runs 14.3s @ ~100mph so far NA with a crap 60ft. iirc that's faster than a stock 340

According to the Road Test magazine "R/T Test Report" from April 1971 for a '71 340 Dodge Demon, yes, it is faster. Best they did was 14.56 @96mph

And I don't care what any of the haters say, that's some really nice work there. Doing a swap with a kit is hard enough for most people, making everything yourself to make it work is a level of skill they'll never have. Maybe a 3.6L isn't the "sexiest" engine swap out there, but that's a solid modern engine. I'd rather see 100 of those than 1 bone stock factory car that spends 99.99% of its time parked.

I have a 3.2 Pentastar in my wife's Jeep Cherokee. It's got less than 40k miles on it, but so far I like it. What kind of mileage do you get in it? What does the car weigh?

Not sure really on mpg since I don't have a working speedometer.
If I had to guess its around 25-30mpg if I'm not hammering it(which i do)
 
You’re getting 25-30 mpg and approaching 13’s?
And what’s the problem?
the least I get in my wife's Cherokee with the 3.2L is 25mpg. Of course that's with an 8spd auto, but you have a 6spd stick, so I think that's not that dissimilar. The big difference might be the weight , that's why I asked.

I bet the handling improves a ton with the 3.6 in it.
Its still not quite 50/50
Weight distribution is a around 52%/48%

But it would depend how much trust you can put into the accuracy of the garbage truck scale at the local recycle center.

I would love to see a kit or manual on how to put the 3.6L in the early A bodies. After driving a 3.6L Challenger, I was sold on putting one in my '64 Dart Conv.
 
The new 3.6can make over 300 hp and weighs less? Power to weight.
 
What rear end and gear ratio are you running?
Currently an 8-1/4 with 4.56:1. It was already in the axel when I got it and I thought its help up the low end torque. But with my T5 2.95 1st gear, it makes for a 13.4 overall gear ratio, so 1st gear is pretty much useless. So I'm thinking about stepping down to a 3.91

good idea. 3.91 or even 3.55.
