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!!

Stubbs67 · 03-07-2011, 12:09 PM

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.

406 Q-ship · 03-07-2011, 04:22 PM

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.

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!

Longhorn Man · 03-07-2011, 04:57 PM

cad 425 here. It's getting pulled out for a small block soon-ish though.

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.

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

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.

brad_man_72 · 03-07-2011, 06:52 PM

don't kill the messenger..... Guy has a 67-72 chevy pulling truck with a ford 460 in it somewhere in southern mo.
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.

Pop's C-10 · 03-07-2011, 07:20 PM

348/409, Buick 401 or 425, 472/500 caddy...My pops had 403 th400 in his 70LWB..that thing would walk...

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

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

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

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.

codeJbird · 03-09-2011, 08:36 AM

^^^^^^^
Mine is certainly not as crazy as that, but it should be pretty quick. i have an 09 Pontiac G8 GT 6.0 w/ 6L80E trans. Not yet running, but I can't wait.

dos0711 · 03-09-2011, 08:43 AM

I know I'm gonna get pummeled, but I like to stick with the same make..."Chevy in a Chevy", "Ford in a Ford"...etc...

**71blksuper4x4** · 03-09-2011, 11:03 AM

409's were done years ago. Some of our early members have good threads from back in the day. Trevor

I can think of more fun places for a "Chevy" than just another 'chevy". Can you imagine what happens to ricky racer in his mousephart powered honda when you pull alongside him in this? What a great place to house an LS2 Corvette motor!

FlounderGDI · 03-09-2011, 11:55 AM

The PO's PO put a Pontiac 400 in my truck... Not too crazy because it's basically a SBC but you don't see many people running a Pontiac motor in their trucks... These pics were from the week I bought it... I have since replaced the carb and air filter...
