Engine swaps youve thought about?

[srziemkowski]

Just putting this out there to see what engine swap ideas everyone has thought about or has done on our trucks?

Mine is a l67 supercharged 3.8 from a monte carlo/grand prix etc...
240hp or 300 with a pulley,intercooler,and headers.
I know i will hear crap about this swap thought but i think this would be a reliable fun cruising engine.

[jimmydean]

I would like to do a 4BT swap at some point (last thing if I run out of other things to do). A Duramax would also be cool, but I think the 4BT would be a ton easier to do.

If I stay fossil fuel, I have thought about either a supercharger or twin turbos. But my project is so far from an engine swap at this point, it's just a pipe dream.

I love the idea of a supercharged 3.8, post up some pics!

[srziemkowski]

Mine is also at the far away point but thoughts and ideas

[srziemkowski]

Maybe even a grand national swap if they were more readily available

[srziemkowski]

My brother was also thinking of doing a cummins swap,said you only really need like three wires or something to actually use it.

[A.T. RockDriller]

Here's one I'm thinkin about....
Cause it's pi$$in me off............and it still aint finished....

But I'm gettin there.

I just had to pipe up on that one.....
I'll take it over to my thread.

BTW...the only addition to this 351E that I've pondered is adding a Turbo.
IMO....the BB V-6's were made for boosting. Might be the best thing a feller could do with one.

I like your little lifting buddy there Les!

[srziemkowski]

Thats a pretty good idea also

[theastronaut]

I really want to put a Vortec 4200 Inline 6 from a Trailblazer/Envoy in my '66 C10. I'd strip all of the factory EFI off and convert it to sidedraft Dellorto carbs (3 two barrels) on individual runner intake manifolds. I'd use a 5 speed from a Colorado/Canyon. I think that Web Cam will regrind the factory cams (nobody makes cam blanks for these engines) and I've found a company that makes rear sump oil pans to clear the crossmember and flywheels to convert it to a manual trans. These things are 290hp stock and it shouldn't be to hard to get it up to ~375hp with the carbs, cams, header/exhaust, and some porting. There's not much aftermarket support for these engines yet but I think there's alot of potential in them.


Besides, how wrong would it be for a 1960's American truck to sound like this!?

Thx, Clyde....
That thing kicks a$$.

I’m pretty conventional in my thinking. I would have preferred a Pontiac 389/4 speed in my truck. I always liked the engine and it would have been way more cool than a small block Chevy. But the reality is the SBC is cheaper than anything else so I’m pretty much stuck with that from here on out.

Have to admit though, having a truck that sounds (and accelerates) like the 240Z in the video would certainly be cool.

I've actually got a brand new 290hp GM crate 350 that came with the truck that's never been used; its paid for and would be cheap to finish up and drop in the truck, but I don't want a "belly button" motor. The Vortec 4200 would be more expensive (three dellorto carbs aren't cheap!) but who else has one in their truck? The truck originally had a 250 inline 6, and the Vortec 4200's are 254 C.I. so it's kinda the same, right?

[gimmy 64]

check out the inliners website there are a couple df guys running those sixes with turbo's

I agree that the low compression ratio is very accomodating for turbos, but I think the issue you might have would be getting the rpm's to the point where the turbo would be effective, since the V-6 redline is around 3600. Maybe after a lot of balancing you could spin them to 5k.

keep the efi, you will quintiple the cost of your engine just buy going to a sidedraft carb setup and it will only perform at WOT. EFI though gives you tuning for whatever, not just those 2 days out of a thousand that you are on a track. Not to mention I had twin sidedrafts on my BMW 2002 and what a ***** to sync and tune for changes in weather...

not knocking your choices, just saying

[Leadfoot Lambert]

I myself have considered the L67 supercharged 3800 V6 swap, I even went as far as buying an engine and wiring harness, biggest problem I can see is the throttle body would be pointing directly at the firewall and too close to put a U bend on it so you would either have to cut a hole in the fire wall and have the air cleaner inside the truck or get a supercharger off an Australian Holden car, they are set up for rear wheel drive already.

Appreciate the input but I'm definitly set on using carbs. Did you have dellortos or webers or _? I know nothing of setting up an efi system, and even if I kept it fuel injected, I'd use individual throttle bodies and an aftermarket computer- the cost of that would be high, and the learning curve steep. If I kept the factory efi it would still have to be reprogramed because of the manual trans conversion and to get rid of the drive by wire throttle and torque management stuff. I've put over 35k miles on my '64 VW Bug that has dual two barrel downdraft dellorto's on individual runner intakes and haven't experienced any bad driveability issues yet. I've never even had to re-sync them except when I've had to take the linkage off to work in it, whitch isn't often. I know how to tune the carbs well (I have a wideband afr gauge with datalogging capabilities) and mine perform just as well in 15 degree weather (once the engine warms up) as they do in 100 degree weather. They are also quite smooth at any throttle position, all the way up from idle; as smooth as any of our newer fuel injected cars. The beauty of dellorto carbs is that everything about them (idle and main jets, air correctors, emulsion tubes, venturi size, accel pump squirter size and linkage throw) is highly tuneable to dial them in for any engine. I'm also getting way better mileage (as high as 36.25!) with the dell's than I ever did with the stock carb. I'd never go back to a stock carb on the bug, the dell's are that much better.

Call me old school, I'd like to do a 401 or 425 Nailhead Buick w/SP400 trans. But not in the truck I have now.
Duramax would be bad *ss in a 4x4 though....

apples to oranges my friend. you are using a well developed carb system with YEARS of tuning behind it on an air cooled motor that is very likely less than 80hp and comparing that to having a custom manifold and linkage made and expecting to better the factory hp. how will you get spark? the 6 cyl is crank triggered with coil packs and doesnt have a dizzy hole. add a thousand, maybe more for a crank ring and hall switch and standalone box.

GM OBDII are just about open source nowadays, you can have the ecm reflashed not to need the trans (except the speed input, but you will have that with a colorado trans anyway) get rid of the key stuff, get rid of just about anything you dont want really. Toyota guys are using the 4 5 and 6 modular gm inlines with trans adapters and the pcm work is 2-500, about 1/5th of what you will pay for your custom carb setup with three carbs. the engine already has everything it needs to run, why would you get rid of it? might as well keep the inline 235 and run duals or triples on it.

[Northern lights]

I have a 348 tri-power sitting on a stand in the shop that will likely find it's way into my '64 shortfleet 4X4. I DO like the nailhead idea though, but I don't have one of those.

[Chevy Fleetside]

500 CI Caddy. 426 Chrysler Hemi. Cummins Diesel. All nice thoughts but I am putting a 454 in it because it was free.

There's a guy in italy (alfa1750 on ebay) that specailzes in rebuilding dellortos and comes highly recommended. He has a pair of rebuilt 40 DHLA's listed on ebay for $500 bin, so a triple setup should come in around $750. Megajolt could be used for the ignition, which runs about $165 I think. Flanges for the carbs and cylinder head are easily sourced to build a manifold with, or I'm friends with a guy who owns a foundry and could cast intakes if I made molds. Individual runner intake manifolds are pretty simple to fabricate compared to a plenum style manifold. The VW makes 90hp and 115tq from 1679cc and runs 9.6:1 compression. Thats almost double the stock power with less than 100cc increase; alot of guys cant get their 1835's to make that much power. Being aircooled (limited ability to dissipate heat) with that much compression means it is very tune-sensitive and the dellorto's are able to make it work. I'm not worried about the cost; if I was I would use my 350 crate engine that is already paid for. Everbody and their dog has a V8 with a 4 barrel or a LS swap with factory efi. I want something unique that hasn't been done to death yet. Inline 6's with triple two barrels are nothing new, but how many people have a Vortec 4200 running triple dellorto's and a five speed? I'm up to the challenge and have never been one to take the easy way out of getting something done. I work until I get the desired results- take a look at my '65 C10 restoration thread and see what I mean, thats my first shot at metal work, bodywork, painting; its my first restoration and it came out great. If triple dell's work well on other inliners, then why can't it work on a chevy? Factory efi is easy and boring, thats not my style. Besides, who wants miles of wiring and heaps of plastic parts under the hood of a classic truck? The soul of a classic is lost when technology replaces simple mechanical parts that one can easily understand and work on themself with hand tools.

I have an '03 Envoy with the 4.2L and it runs good and with the EFI is pretty good. I could see it working in one of our trucks just fine. Not fast by any means but quite acceptable for a light duty pickup.

Me: I have a fresh '64 409 that I think would be really cool in my '65

[Woogeroo]

I couldn't afford the gas.... but, a big block cadillac 500 motor.
