Unusual motor swaps... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

68,69 K20 · 03-07-2011, 10:28 AM

Just curious how many out of the norm motor swaps have been done to these trucks. BBC and SBC's are cool and all, but how about a 348/409 swap, or even something radical like running an ol skool flathead or even and early Hemi or something along those lines.

Anybody done something different or know someone who has?

**special-K** · 03-07-2011, 11:27 AM

I already have a built 327 for my '67 GMC,which was the top dog for power and pretty limited production. But,if I could do it over I'd like a Pontiac 389. My theme,other than using what I have,is a '67 era truck that might have been worked over by a performance minded wrench. Since GMC would have been sold at a Pontiac dealership I thought it would be cool to have it modded with Pontiac stuff that may have been available to a mechanic at a dealership. I have a Pontiac steering wheel,dog dish caps,and M22 from a GTO already. Add a 389 tri-power and some GTO seats,maybe twin tip duals poking down from behind the rear wheels...WOWZA!!

I looked at my truck the other day, then looked at my wife's '76 300d Mercedes with good motor/trans, I hate that car.... I had a thought...... nahhh.

Beat68CST · 03-07-2011, 05:31 PM

My grandpa pondered puttin our stroked 348 with 690 heads and matchin 750 comp series dual 4's in my truck.

Then we thought about the cost going through that compared to my small journal 327. lmao.

There is a member on here who has a Buick 455 in one. I'm sure there were more than a few got 472/500 Cadillac, it was a popular swap into the square series and the 67-72 isn't much different.

I'm in the 500 caddy club.....I will say that something along the lines of an Isuzu diesal with an auto out of a small box truck would be Kool and easy

70 shorty · 03-07-2011, 04:50 PM

a 348 or 409 would be really cool, but I think it would be even cooler in an even older truck, say from when the 409 was actually produced. Special K, I love your idea!

I had a '65 caddy in high school with a 425, that was a great motor. Good mileage and a ton of power.

I have the 5.3 swap in mine.

W block or nailhead would be cool but I'd rather see them in something without a hood.

There is another 460 going in one in LA too. I have 4.8 in mine..........not running yet, but in

i would love to drop a cad motor in one. you going to sell your cad engine when you swap it?

suville · 03-07-2011, 05:57 PM

Not too unusual but a bit different and can be accomplished without goin to the extent that I have but this is a real cobb job installation was that way when I bought it and am in the process of complete reconstruction.

Here's a '68 GMC powered by a Boeing turbine:

YouTube - Jet Truck Burnout

YouTube - Jerrys Jet Truck Full Video

I've seen other unique swaps on here as well, Pontiac 400s, 6.2/6.5 Detroits (something I'm thinking about on my next truck), Cummins. I was reading somewhere about a 4-cylinder into an Action Line truck, but I can't find it offhand.

ChevLoRay · 03-07-2011, 07:33 PM

Somewhere on here was a video clip of a '67-72 that was running a Detroit Diesel V-6, with an appropriate gearbox (10-speed?). In my opinion, that was pretty ingenious.

60ratrod · 03-07-2011, 08:24 PM

i read about the turbine powered 68 in hotrod couple years ago. and the way that he managed to hook the tranny to the turbine is friggen nuts. anyway, what about one of the "twin six" v12's? i know a couple of the 60-66 cats have done the swap and their 60-66's look awesome.

crazy longhorn · 03-07-2011, 09:19 PM

I did a 425 Cad, & a 455 Olds both in my old truck....lookin at an LS swap next trip

cam.man67 · 03-09-2011, 07:48 AM

This isn't an Action Line, but here's a unique one I saw in January, a Jeep Wagoneer with a Ferrari Motor. The creator, William F. Harrah, wanted a 4x4 SUV that could travel 140...I guess it worked. He had to increase the length of the hood by 3", and even then is was still a tight fit:

It's a DOHC V12, but what's amazing is that this sucker only displaces 267.9 cid, yet it takes up that much room...when people say that Europeans have always been smarter about engines and efficiency, I just laugh.

The first two pics are not mine, the last one I took.

that "jerarri" is in Reno at the auto museum. iv seen it, it is truly a unique monster.

Was thinking about putting my 440 R/B in my truck!!!

ChevLoRay · 03-09-2011, 01:46 PM

When the 88-98 body style was new, I remember one of the truck rags had a pic of an 88 or 89, that had "Like A Rock, With A Ford Block" on the tailgate. Kind of a slap in the face.....

4x4360 · 03-10-2011, 06:33 AM

Recently bought a '67 C10 with a Olds engine installed. Still trying to figure out the size and year. I think it's a mid 50's because it has center bolt valve covers and reverse gear is at the bottom of the gear selector. The previous owner didn't know either. Has plenty of power but I'm looking for a period correct small block to put in.

I did that. Took one from an old 69 Imperial along with the 727 and stuffed it in a '70.
Worked better than the paltry 350 that used to reside in there.
