Has anyone ever done this? I was thinking of a 383 with a single turbo and a blow through Barry Grant Mighty Demon...Any pros and cons to a setup like this? I'm thinking on a budget..

Re: 383 Syclone

kgbpilot used to have a turbo v8 with a blow through setup on it. pretty sure he sold it though. It was pretty fast if I remember correctly.

Plus it had a wicked stance.

Re: 383 Syclone

yeah there is a couple around and no it is not cheaper.

Re: 383 Syclone

There are A LOT of v8 swaps ... not so many with a turbo ... but the space is there.

Taking the v6 out of these things drops the value a LOT ... so keep that in mind. You sound "money concious" to me.

If its performance over anything else ... go v8 ... they are a LOT cheaper to modify for power than these 4.3's ( $3k billet crank for a v6 ... ouch ) ---

Re: 383 Syclone

more reliable yeah but no not cheaper. a v8 rebuilt stock vs stock or even mildly built are the same then when you have to make custom headers, down pipe, ic, fuel lines, and all the minor changes and parts you will have to buy to retro fit it is going to cost more. i guess if you did all junk yard parts and engine you may come out the same or maybe a small amount cheaper.

i don't see how it couldn't be cheaper. i'm sure it'd be more reliable

Re: 383 Syclone

The V6 costs too much to build then it just breaks. But your truck is worth more with the 6.

If you can make your own parts(headers, downpipe especially) and buy your parts used you will spend about the same for a faster more reliable V8.

I'll sell you a set of headers that you could modify to work for cheap :D

I personally think that blow through carb is going to hard to tune and lose a lot of driveability. I know that Woundup used blow through carb with Twin Turbo and a 350, that truck has since been converted ot fuel injection. IMO Fuel injection Intakes and fue injectors don't cost that much and with the Code $59 you don't even need an aftermarket ECM. Having ht eability to control fueling, timing through an ECM is very beneficial with a turbo.

IMO a V8 turbo isn't going to a budget build. You might be able save some money using many of the cheaper SBC parts, but the cost of cutom headers, IC pipe, turbo, a 4L80E transmission that can handle it, etc. is going to be an expensive project.

Re: 383 Syclone

As mentioned it depends on what your goals are. I can only tell you what I have spent so far and I know it could be done a lot cheaper, I also did 99% of the work myself except the transmission.

Here is my tally from a post I did on another thread.

Lets see, I bought the truck in 98 as a wreck, paid $3,000 for it. After fixing it back to mostly stock I had somewhere around $18k in it. Damn front bumper cover alone cost me $800 back then.

So if we ignore the 6 cylinder mods I did through the years since they are gone.

Engine basically I had left over from my 67 camaro, although the last time I had it built at machine shop was $5k bill. (reason combo isn't perfect for turbo at 9.8:1 compression)

  • 4l80e ~$9,000 in ($1800 transbrake, $1,000 convertor, billet shafts, etc.)
  • 2 gt35's. $2,000
  • 2 wastegates ~$500
  • Had to have heads redone. $400
  • Add roller cam and retorfit lifter $750
  • Injectors (84#) ~$350
  • Rear suspension ~$600
  • Front Suspension ~$500
  • Brakes ~$1,000 (all new lines, calipers, line locks, etc.)
  • AN fittings/hose at least $1,000 there.
  • Fuel pump (weldon used) $300
  • Exhaust $500 (did labor myself, just paid for bending)
  • Headers and coating $900
  • New tires $450
Ignore the many trips to hardware store, autostore,

So total of the big items is ~$36,250 and I am not done yet, future plans are some interior work, roll bar, redo some paint, another set of rims for racing... maybe even a new motor if I get greedy on power (dart block?)

The way I look at it is I would have probably spent the money anyhow, this way I have something to show for it and enjoy doing it.

But as mentioned the stock ECM can run a v8 very easy. All I had to do was get a newer camaro distributor which plugs in identical to our v6, add 2 injector plugs, and use a camaro memcal. Switch code59 for 8 cylinders and it works fine.

The woundup truck is now in chicago/detroit area and a member on this board that has a busy career. It is now fuel injected as the carb was too much hassle. It can be done just not sure it makes sense when the fuel injection is already 90% there.

Re: 383 Syclone

...not that this answers your 383 question directly, but in the latest Hot Rod Mag
a gentleman asked a similar question about "costs for a twin turbo 327 build".
Their reply was this:

"Here's the typical ballpark figure...you're looking at nearly a $25,000 outlay!"

Turbos......................$2,000
Wastegates..................$1,000
Fuel Management.............$2,500
Intake & injectors..........$1,000
Throttle Body.................$400
Hi Capacity fuel pump.........$500
Custom Headers..............$5,000
Intercooler and piping......$2,500
Engine rotating assbly......$2,000
Cylinder Heads..............$1,500
Block Machining-balancing...$1,000
Hydraulic roller cam-liftes...$800
Roller Rocker Arms............$300
Misc engine parts.............$500
ECU Distributor, coil, wires..$500
Engine assembly labor.......$2,000
Tuning via chassis or dyno..$1,000
Total $24,500


Finally, there are integrated aftermarket all in one kits,
but most of them are designed for 350 or larger small blocks.
In theory, by varying turbo compressor and turbine wheel
parts they could be adjusted for the smaller 327s. Two leading
twin turbo kit vendors are Gale Banks and Nelson Racing.

Some of those estimates a bit high... while $5,000 for custom headers is possible, I would hope you could get it done cheaper.

But I think your better option is to fix the six. There's something cool about stomping mustangs with six cyl.

If you wanna do a 383, get a regular s-10 or sonoma.

Here's a sampling of what my build cost:
98' Sonoma X-cab Stepside..................$5,000
60k mile LT1 w/T56................................$1,500
Forged rotating assembly.....................$1,500
Ported LT4 Heads...................................$1,200
Machine Work.........................................$1,200
Spec Stg II clutch......................................$300
Coated Shortie Headers.........................$300
58 mm TB.................................................$300
1.6 rr's......................................................$300
Ported LT4 intake....................................$250
Comp Cam...............................................$250
30# Injectors...........................................$200


There's more to it... but I don't want to think that hard. Nor do I want to add it all up :roll:

No power adder, yet. But I still haven't gotten a clean all motor pass in.
