Default 240 swap to Ford 302 or 4.6?

I've seen some very sweet Ford 302 conversions in a 240 over the decades (350 Chevy too, but we are Ford guys). Now in 2022, the 4.6 has really proven itself in Crown Vics and under old F100 pickups (we are building one). And we happen to have spare CVPIs for parts. The standard 2v 4.6 motor gives an honest 250hp and good torque. The 4v Marauder/Lincoln motor has more hp but at higher rpm. Parts are spendier for the 4v.

Is anyone here running a 4.6/240 FordVo? I was thinking the 4.6 would put less weight on the Volvo front suspension than the 302 Ford, but they are about the same weight and the newer tranny may even weight more https://thedriveradviser.com/the-wei...-1961-present/

I found quite a few 4.6 conversions in a search engine. https://presearch.com/search?q=Volvo+240+ford+4.6

You can source a manual from a Mustang, but supply is limited. However the sturdy 4R70W or sturdier 4R75W auto is found in all 4.6 CVPI police interceptors.

If you look in projects, there is someone with a 240 with the 4.6 swap.

Found it. http://turbobricks.com/forums/showthread.php?t=343681

So, the sbf 5.0 used to be the go to. Narrower and stuff. The 4.6, from what I’ve been seen, can fit but it’s super tight. Ls motors are more popular cause they’re narrow like the sbf’s and have a ridiculous after market.

There’s 2 4.6 swaps that I know about. The motor fits but the vacuum brake booster won’t. You either have to move the brake setup or (easier option) convert to a hydroboost which does fit, just barely.

I just can't imagine trying to change spark plugs on one swapped with a 4.6. Yikes!

For all the trouble of installing a 4.6 I would scope out whether a 5.0 will fit. The Coyote 5.0. They are amazing engines.

That would be super neat! They really are incredible engines.

5.slow from a foxbody fits so so so well. I can send you pics of the motor mounts I made, they're much easier to fab than the Converse/JTR mounts. Grab the t5, slap on some cheap aluminum heads with small chambers (less than 60cc), a mild cam, what ever intake/carb suits your needs. ~300hp and can be done on the cheap.

If all you want is v8 noises and torque, it's hard to beat the 5.slow in a 240.

Or an Ecoboost 4 banger. That car is awesome.

Very cool. Thanks for posting that one. I have never seen that build thread. The little (small displacement) Ecoboost is also an amazing engine. The 2020 Mustang 2.3 makes 350 HP from the factory. When I ran the Enduro event Oct 3rd there was a 2020 Ecoboost Mustang with the Performance/Handling package on it that also ran. He was only 1.6 seconds behind my record setting time in my 5.0 V8 GT. Impressive, to say the least.

Ditto on the sbf 302. I know there's better, more modern, more sophisticated engines, but it's so darn simple and fits so well it's almost as if the sbf windsor people owned 240's. If you're looking for the ultimate in simplicity, the 302 is hard to beat.

Junkyards round these parts are loaded with 5.0's from exploders with the gt40 or gt40p heads. Decent JY power for less than $300.... and when you're ready spring for better heads.

Even the gen 1 and 2 sbc fit really well in the engine bay with plenty of room for headers and such.

Heh, I saw an NA MIata at the autocross on Sunday with an Ecoboost in it, and a LOUD AS HELL fender exhaust. That thing MOVED.

What a great conversion. When I ran with the Oregon Region Porsche Club of America in Portland last month there was a Miata with an LS3 in it. It was out on course and I instantly recognized that LS sound. WAY too much power.

I didn't realize that the 4.6 is so wide. With OHC I guess that makes sense. Changing plugs would be a nightmare and I don't really want to dink with the stock Volvo brakes, which work well. If it ain't broke ...

Leaning for the 302 now, for sure. Love that classic V8 thump sound. 4 cyl sound ... no thanks. Only Saab Turbos sound good, imho. Wish I could find an old Saab 99 T with Aztec wheels but they are super rare now. Mine ran 15psi, water injections, and left stock Corvettes behind over and over. Back in the 80s.

A son is putting a CVPI 4.6 frame and motor under a Dentside F100. Some day. We'll see ...

I recently picked up a 1983 Volvo 245 with a 1989 5.0ho and a tremec 3550 in it. have had lots of problems due to that car being in to many hands over the years. But the couple times i have driven the car it is very fun. It is all stock motor and is still fun. Its an odd experience hearing the v8 when you are used to these cars being 4cyl.

One of the things that's appealing to me with the Ford swaps is the Ford automatic is a 4 speed with electronic OD like an AW. Fulling integrating the factory shift lever would be a make or break the swap for me. I personally think an 5.0 sounds better than an LS.

The 4r70w out of a v6 mustang fits in a 240 no problem, but getting the 3.8L v6 mustang shifter to work was a difficult proposition. In the end I had to extend the volvo 240 shifter mechanism beneath the car and welded on the nub for the stock v6 mustang shifter cable. Works so far.

If it helps any, plugs are on top of the heads.

Ah yes, we did them on my daughter's P71, along with new COPs.

But the big issue would be messing with the Volvo brakes. I like Volvo brakes. Always have.

Having owned a 5.0 swapped 245 I can say it was a ton of fun but I also bought it that way. If I were going through the trouble of swapping a v8 into a Volvo, I’d just go LS. The 5.0 is a perfectly fine engine and makes good power but an LS just does the same thing even better. Plus the outdated ford EFI can be a headache when it starts acting up. Either way it’s fun.

I own a B230FT swapped 245 now and it’s arguably as fun once you’re in boost. I do miss the torque of the 5.0 though.

First turbo brick I rode in belonged to the parts manager at my Volvo dealer. Flatnose 244. He went on about how I was going to love it. Hold on, he said, and nailed it in 2nd.

Uh....uh....where's the power? .... then WHAM it hit hard at about 30mph. I drove in there in a 744td and left in a new 944T. It was that impressive.

His brick was far from stock, but he had not gone the water injection route I did later on my 944T. And the earlier turbos spool up slower than the 900 smaller units. Still, it was a rush. He just kept grinning at me. I lost touch with him, think he went to work at a Toyota dealer.
