Long story short:I have a 1989 E350 7.5/C6 is knocking and burning oil. Tranny is fine. Been keeping my eyes open for an engine. But I found a whole van for $500. Runs and drives like a champ. 1985 E150 4.9/3ontree. And yes I already purchased the 85.I figured it might possible to swap the drive trains since I have the complete donor. I like the 3 on tree but would rather have a floor shifter.And info on the net is scarce about the 3 on tree tranny. Are these as hardy as a c6?What are they called? I parked the donor beside my 89 and the project seems feasible. I cannot lose b/c the 85 is woth more in scrap than what I paid. And that 4.9 feel like a winner to me,plenty of pull with that manual. Your opinions of proposed swap please.

 

I'm doing something similar. I've got a 89 E350 Clubwagon. Mines a 5.8/C6 And I'm swapping out the C6 for a NP435 4spd. Eventually I'll swap in a 300 too! I picked up a 88 E150 with a 300/5spd for a donor. It has all the manual transmission conversion parts except the transmission & bellhousing. Here's a pic of the dog house in my 5spd donor van. On the 5spd's and the T-18/NP435 4spds the shifter comes thru the rear of the dog house.



Your swap idea is doable. You'll have most if not all the parts you'll need. Depending on your van's wheelbase you may need to have a driveshaft made up or modified for your E350. The three on the tree is fine for the E100's & E150's. But I wouldn't run one of those 3spds in an E350. For an E350 I would swap in either a NP435 or T-18 4spd. They are both much tougher then the 3spd's.

 

The t18 has a non synchronized first gear, which makes them a bit hard to live with in the city. You have to RPM match and double clutch to get it to go into first from second if you are not completely stopped. Not that you will have to very often, 1st is a big time granny gear in those things.

The NP435 has a GIANT jump between 2 and 3, like 3.34 -> 1.66 I had one in an older pickup. You couldn't really jump to 3 if you were loaded and not on a level highway.

 

Could always find a T19, they have synchronized 1st.

But you really don't need first in the 4 speeds unless pulling a dam good load.

 

Both the T-18 & NP435 are non-synchro grany low first gears. Most people don't use 1st unless they are hauling a load anyways. They are also both nearly bullet proof. Which is why I'm a big fan. I personally prefer the NP435 over the T18. Don't know why, I just do.

I've done a lot of hauling/towing with the NP435's and have never had an issue with the gear ratios. And that was behind 300's, 351's and even a couple 302's.

 

Can't help you on the swap info, but as far as that 300/6 goes....yes it's a very good engine, lots of bottom end,
drives very much like a
diesel but it's still only about 150 HP and not much more torque. You may be very surprised after driving a 460.

 

150hp? That it for and 300? Well it sure feels like a champ anyways.

 

Yup, that's all they ever had. Lots of folks love their 300s and swear that they won't die without permission, but they don't win many races.

 

They made 150hp/265ftlbs in fuel injected late 90's trim. They also made 40-ish ftlbs more torque when they became fuel injected. The carbed engines in vans made a hair over 100hp, but could be bumped a bit with tuning.

 

Depends on what you do to them! Not mine, but I wish it was!!

Slap the 300's 1V carb and restrictive manifolds on a larger engine and see how little power it makes!!

With some modifications the 300 can make good power too.

Huh...I guess they can.

Sort of an uncommon thang though.

 

That dragster in the first video makes over 500 hp.


They are different! But different is good!! No belly button V8!
