A reader has two questions about a Wagon and a Truck

• CATEGORIES: News This site contains affiliate links for which I may be compensated.

A reader named Steve had some questions about which I didn’t have answers:

He asked me to post two questions for two different projects:
1) What would be the easiest/best/smartest engine swap for an F134 in a 1947 W-O Truck?
2) What chassis swaps are recommended to modernize a 1952 W-O Station Wagon?

Thanks!

    Ans.1) The easiest/best/smartest swap for the original L4-134 in a ’47 Willys PU is an F4-134. It bolts right in. All you have to do is change the linkage to the carb, and maybe switch the battery to the other side. An F4-134 has 72 HP (adding 9 HP) which is all you need with 5:38 gears. If you want to have a freeway hauler, buy a Chevy and use your Willys for real work hauling on local roads.

    A modern V-8 can maintain a little more RPM’s, but that doesn’t gain much speed with your low rear end gears. A lot of work swapping, little gain. If you’re going to modify the engine, you will want to modify everything. However, you must remember that the rear wheels don’t track the front. So, if you install modern pickup axles front and rear, then the front axles will stick out past the front fenders. Did I mention, keep it stock and “buy a Chevy”?

    Ans. 2) Assuming your Wagon is 2WD, several people put a Willys Wagon body on a Chevy S-10 chassis. Why bother? Just buy a Chevy S-10.
    The old front ends were not designed to drive 70 mph, or drive fast around corners. Willys America offers a bolt-on front end kit to swap a 2WD Willys Wagon/Jeepster with a stronger, more stabile unit so you can drive Freeway speeds with modern running gear, utilizing a Ford 8″ or 9″ rear end, which is about the right width. If it’s 4WD, the factory power train will pull and climb anything. Just drive it as it came from the factory!
    If you still insist on re-powering, a Chevy engine/trans. is easiest because parts are cheaper and very interchangeable. I prefer a Chevy 6 cyl. engine unless you want a hot rod. V-8’s have too much power and you will break things, including traction. (Either Chevy 6 or 8, you will probably need to cut the firewall. Ouch! Don’t do it…)

    There’s nothing like a long stroke 6 cyl. for off road driving. That’s the reason my favorite off road engine is a Willys L6-226. Don’t do that swap, just buy a ’54 to ’62 Willys that already has one.

    Biased opinions by **Steve E.**

    (P.S. I’m not partial to Chevys. I like Fords as well as Chevys, next to Willys vehicles.)

    Hey Deilers

    Ilike the old trucks and been checking out what other people have done,,I think the easiest way to go is to buy a old w150 80s model Dodge pickup,, 318s are as easy to find parts for as chevys,, if you find a 440 Dodge truck even better as the distributor is in the from of the motor like the AMCs that were in Jeeps,,I think the wheel base is worked out by cutting some of the frame & makin it shorter…And since the trucks & the station wagons are ether the same wheel base or real close the Dodge would work good on ether one,, I built a 63 Willys truck by just changing motors to a 327 chevy & all I did was tried to ram 400 horses though a Tranny & transfer case rated for way less,,,

    Im building a 60 Willy 3B with a 74 CJ-5 running gear under it ,,, I cut the body & added 4″ to make it fit the 74 frame & using All JEEP runing gear,, AMC 360 ,,still find them at junk yards in 80s Cherokes…. Wish you luck with what ever you do,,
