replacing 300 with a 200 or 170.

I have a 300 in my econoline. Will a 200 or 170 bolt right up to the same 3 speed tranny? Can I also use the same driveshaft? ( I have a 9 inch rear axle BTW and the cross brace like 65 up vans)). Seems it should be a simple swap and only need to change engine mounts ( which I can fab up any way I wish).

True or not? Am I missing anything?

I'm more concerned with gas mileage than power. After driving around the last couple weeks I feel the 300 is over kill in my van..... for my uses.

The 170/200 use a different transmission, flywheel and bell housing. If you get a crossmember from a 65-67 170 it will bolt right up but you will also have to get the bell housing, flywheel, clutch equalizer bar, and transmission. The transmission has a small yoke which will not fit your front u-joint. You can remove the yoke from the 300 transmission and install it on the 170 transmission. You will also have to change the radiator, the outlets are larger and one is on the opposite side. The 170 radiator will not line up with the 300 radiator support so you will have to drill some new holes. Throttle linkage is also different but should be able to be adapted. Best to find a complete truck with all the stuff on it that way you will have everything you need. I know where a few are in the northeast.

ahHHHHHHHHHHHH........TOO MUCH.

I was hoping the bell housing swap would be the most I'd have to do. Changing trannies and radiators and.......and.........and................is too much changing.

THIS IS WHAT I HATE ABOUT FORDS!..........I love the look of the Econoline best. But a good old Chevy always works out the best all the way around in any car or truck.

I wish now I would have found a Chevy van. More parts, easier to work on & most stuff can be swapped around.

I'll pass on finding another Ford truck. If I was gonna buy another truck it would be a CHEVY!

Matter of fact..........I'll likey start looking for a Chevy van next. And just keep the Econoline too or swap it off.

i have a 170 with tranny that ran well when i took it out if your interested

pm................om the way.

I love my 300!
Fresh rebuilt '75 Engine with hypereutectic pistons .30 over, milled head .030, melling torque cam, MSD. stock intake/carb so far.
It really moves the van. I have less than a 1000 miles on it and it's coming closer and closer to 15 mpg.
Just received the HD exhaust manifold that will go in with an offenhauser intake and barry grant 575 street demon carb.


My buddy replaced his tired 170 with a small block 4 cyl chebby, 4sp. od trans and 2.75:1 posi track. He reports excellent gas mileage.

YEP.............mine really "moves too".................but I'd rather have 25mpg than speed. I'm a low end torque kinda guy anyway.

PS..........Funny thing about a freakin FORD.............I have a 75 c-30 1 ton pick up ( Chevy)............4 speed..... 292 inline six ( the BIG Chevy six).....zillions of miles on it and it gets 25 mpg..........???????????

And pulls harder than the FORD 300 to boot! NO SHIT SHERLOCK. Now you FORD freaks may become disenchanted hearing this......but truth is truth.

I love the "looks" of the Econoline best...............but in retrospect...............I should have went Chevy flatfront............And wish I had. CHEAPER & EASIER TO FIND PARTS........better inter-changability...better gas mileage.........and more dependable. I'd trade my Econoline for a Chevy tomorrow.

BUT...............my last FORD econoline had a 200 six in it ( transplanted from an old Maverick) ..............I loved that bitch..................just the right power and great MPG....but the FORD parts train can not compete with the Chevy parts train.

( I KNOW...........I'm now booted from the Econoline club....... ........."you'll have that" )

WE SHALL WORK ON IT.........................

Don't get rid of the Econoline just add a Chevy !!
This is 2009 diversity in the family is no longer frowned upon but welcomed.

LOL.....
Let's see...........in my driveway is
1-jeep
2-Subaru
3- TWO SPITFIRES
4-Old Bug
5-Karmann Ghia
6-Cavalier
7- 64 econoline
7- nova
8-schoolbus
9- 75 Chevy pick up
10- Bradley GT2

SOMEHOW.......I do not think I need the "diversification".............

Although the Econoline and it's 300 is a very smooth running booger...............No problems there at all.

Just wish it was a nice old short bed Chevy with a good old 230 or 250 SIX with a itty-bitty 1 barrel.


TRADES ANYONE?????

What is that cross brace you mentioned?

PROBLEM SOLVED..........Bought a Chevy.

Can't go wrong with a chevy!!

I sure as shit like the 250's gas mileage better than the 300's...........

And the part inter-change and availability can't be beat with a GM.

Poor little 64 Econoline just sitting there now............waiting for a new owner to finish her off & love her.
Poor old girl.
I took her out for a spin today so she would stay all nice and charged and lubed up and not feeling too abandoned.
