Hmmm....I'd like to have that extra getupngo, but I don't want to sacrifice highway driving

i was pulling 2550 at 70mph, you dont even take a hit on highway mileage, GET THEM!!!!

and do a PI swap too, the way the NPI motors die over 5000 rpms is sad...

PI heads + cams +4.10's = WAYYYYYYYY too much fun

I'm looking for 375rwhp/375ft-lbs with a V3 Si-Trim or a KB 2.1, but I also drive this beast in the winter. A S/C + 4.10's, I might as well walk when it snows. This is also a couple years away so the plans may change depending on what parts I come across for cheap.

Thats one of the very reasons I went with 3.73s personally. And no matter who denies it they will affect the highway mileage a bit the OP even pointed that out in the second paragraph in his first posting. Going with 3.73s with my auto I only lost like 2-3mpg highway and on the high end 3mpg loss from/x a 15.7 gal tank = 47.1 less miles per tank. Some ppl care about that others dont. To each is own. But to Honestly answer your concern about that with the higher cruizing rpm on the highway yu will be burning more gas so your highway mileage will go down a bit. It still would be fun though no doubt.

Just use this to plug the numbers in and do the math from there. http://www.paladinmicro.com/SpeedInGearCalc.htm

I've got the Grand Caravan for highway journeys. The last time we took a trip to Colorado we filled the Caravan before we left and got back to Amarillo without getting gas and we still had over half a tank left, and it was a 440 mile trip.

That doesn't sound too terrible. I think I'm around 2200-2400 at 70-75mph. Not really worried about the gas mileage...I didn't buy a gt to get 30mpg )

PI heads are on the list. Need/want shocks struts, springs, cc plates, flsfc, lca's first.....then the gears, then work on the motor.

Maybe I misread your point or question or the point of that statement period. My bad for laying that out for ya then! Post #24 was kinda a response to the statement You made at the end of post #21!
Luck with your project.

Wow, talk about deja vu. My wife drives a newer Durango. But my work commuter and DD is a Grand Caravan. A 97 I bought for the wife new after we first got married. Now with 147,xxx miles and three accidents (all her). I sometimes feel like tinting the windows in that. Almost ashamed to be seen in it...lol

What year is yours?

I agree WHOLEHEARTEDLY, my freind.

it's a 2007. We call it the 20 Grand Caravan due to the crappy deal we got on it and the high finance charge. oh well, live and learn.
