Think about it. Torque peak is mid 3000s rpm and hp peak is upper 4000s, so you really are doggin it anywhere below 3000 rpm, which is where these vans are from the stoplight. Once the RPMs get up the thing moves pretty good. So I figure it probably comes with a 1500 rpm stall converter, but could use perhaps a 2500 stall converter or more. But would that affect the drivability of the van, especially in rain or snow?
Well, I am not going to do it, too costly, just seems like the real problem short of actually having a torquier engine in it.
High stall torque converters build a lot of heat. That is that last thing they need. Also, a high stall converter does not change the shift points, which to me would be a better solution. Just adjust the kickdown cable and get an adjustable vacuum modulator. That will make the transmission more responsive to throttle, and will cause it to hang in the gears longer.
What the 3.0L really needs is a supercharger.
The 3.0L is built for economy. And that it does fairly well. It is perfect for old grandmas that never actually push the pedal anyway. For the rest of us, the 4.0L is the only way to go.
any one know what the compresion ration is for the 3.0l? i bet a supercharger from a 90's fire bird would fit and work nicely... i might replace my powersteering pump with a blower (it hardly works as is... stupid pump... plus i've moved my car before w/o it actualy running, and it turns just fine w/o power steering)
also... my 3.0 gets hella quick when i mash it and it jumps up to like...45-5200 rpms... then it shifts to a diff gear for lower rpms... can the 3.0 handle high rpms? 5spd swap is lookin more tempting all the time...
Good points. Mine has a 3.73 rear end. I think a 5.10 rear end would solve my main problem. That or a higher torque multiplication factor in the torque converter (multiplier).
Then there is always brake torqueing. Oh, that's heat again.

I sometimes mat the pedal in my 3.0 and out of first gear it usually will shift around 5700 rpm. What a rush!
Also I often run it up to 4500-5200. I think this engine is practically indestructible. Only way to kill it is to run it with a nasty spark knock. Otherwise it will never die.
Yeah, the 3.0L is more bulletproof than the 4.0L., and both are excellent engines.
Revving it won't hurt it thats for sure.
You would not need to remove the power steering to install a supercharger, you can probably fit a supercharger in the space above the power steering pump. However, you probably wouldn't be able to run a standard air to air intercooler. An air to water intercooler would work well.

3.0 Litre runs like a rocket with Lucus UCL in the gas tank!
Anyhow, great to have a faster engine but then you need to upgrade the rest of the vehicle to cope with the extra speed & traffic tickets!
What my 3.0 Aerostar needs is a 4.9L I6! Now that might just torque that unique partial frame welded to body arrangement. I would not mind a big doghouse sticking back between the front seats at all if it held 4.9L of gut wrenching torque. Consider the 3.0 and the 4.9 have approx the same hp, but the 4.9 has 100 more pound feet of torque! Also, go with manual tranny to eliminate shifting problems and tranny heat buildup.
Actually, what my 4.0L Aerostar needs is a 2.0L L4 engine.
I'm giving my teenage son the Aerostar, and I want it to be as sluggish and slow as it can be. 0-60 in two days, here we go.
hahahhahahahahaha couldn't agree more... my first, and only ticket, was when i was pulled over doing 70+ in a thirty five on my 17th birthday at like... one in the morning in my dad's 4.0 awd... i almost went on my self when i saw the lights in my mirror, i was sooooo scared....
Has anyone done any measuring to see if the I6 would fit with a longer doghouse?
I'm thinking it would have to be installed from the inside of the van after a lot of metal surgery.
Also, it's not a high-revver, so torque would have to be depended upon to do the job.
