Ditching the 383 stroker? (1 Viewer)

[Tank5]

Would you ditch a built carbureted 383 stroker with toyota 4 speed for a 2uzfe and auto 4speed. This is for a trail truck that is street driven?

The reason I am asking is I don't like the carb, so I either invest in a efi set up or install the 2uz drive train that I have already. I would just add a NWF black-box to the 2uz set up.

I only want to spend money once on this project, so the planning matters.

 

[bikersmurf]

I only know what I google just told me about the 2uzfe.

That said, the 383 has a much longer stroke and inherently more torque. For my money I’d add fuel injection before figuring out how to put a Toyota V8 in its place.

 

[bikersmurf]

On second thought... 383s are boat anchors... I’ll swing by and haul it away for you.

 

[cult45]

Yeah can you ship that 383 down under?

Fast EFI or equivalent would be my go to. Especially given that you're familiar with that particular engine. Roadkill did an episode where they bolted up a Fast unit to a junker V8 in the middle of some cold nowhere town and boom - instant drivability. It was some old beater wagon thing.

While you're there throw a split case H41 in over the earlier type [if you have one]. Much quieter. Much more advanced. Same bolt pattern.

Fast I've heard has some customer service issues. Sniper would be my choice. The 2uz is a ok motor, very reliable. But takes up a lot of space for the amount of liters it has and a 2uz has little aftermarket support as well as very thin connecting rods. I would stick with the 383 without hesitation.

Yo Tank, where do you live? I might be interested in that 383 and 4 speed if you're anywhere nearby.
Btw, my Chevy 327 runs like a top, having the Sniper efi.

X3 for sniper! I actually enjoy driving my cruiser with a 1f now! It has never run so smooth or quiet.

It’s budget friendly and you can purchase the holley dual sync distributor to finish it off and control timing. Your 383 would be a total different beast. No doubt about it.

There are other distributor options, but the dualsnyc makes for easier setup.

You could also look into some Multiport options, but not your talking big bucks.

383 was a great engine. I know I have one many moons ago.

 

[Tank5]

I appreciate all of the quick responses. The consistent response is to install efi on the 383 and run it. This is the way I am leaning, so I am not ready to give up the boat anchor yet.

I know the 383 will out perform the 2uz, maybe not outlive it. The reason the 2uz swap was brought into the picture is because I have almost everything to do it so cost would potentially be cheaper. It would definitely take longer.

The other uninformed perception that I am under is that the 383 stroker is the old school chevy swap which has been replaced by more modern LS swaps. Am I correct in thinking this? I know that was not my original comparison. It would seem that the 383 still has a place here for swaps. What is the advantage to this old school engine compared to the newer LS?

Grousmen implies it was a good motor?

 

[White Stripe]

The LS motor is a very robust motor right out of the box, has great hardware stock, and very smooth and can be fairly easy to emission compared to older motors that have additional and more complex emissions equipment. Its also easy to reprogram the ecu for additional mods and can be modified endlessly. For example if you want to install a 200 amp alternator on a LS motor its 100 bucks for the alternator. Aftermarket swapping support is also robust for the LS motors. If you don't need any emissions equipment where you live if you do a motor swap a LS motor is even easier to swap and simple to wire and doesn't use a distributor which is nice, just coil packs. If you are doing a motor swap, and you have a choice between a 383, a LS, or a 2uz, I would choose the LS unless the 383 has some very nice components in it.

 

[74fj40]

In a short answer, there are no advantages. An LS is hands down the most practical motor to swap. Cost and support.

But I would still give the 383 one last chance.

 

[Michael B]

The 383 has better torque than a stock LS.

 

[Tank5]

Thanks again for the responses. The 383 runs strong so I am going to keep it around. I am now hunting for an efi kit to put on it.

 

[bikersmurf]

383 is an old generation motor.

When my ‘69 350 packed it in, some members were telling me it was backward thinking to replace it with 50 year old technology. It made sense to me to put in another low mileage ‘72 350 I picked up for $300 with a TH350 trans... I gave the auto to a good friend. 50 year old technology for a truck built using even older technology.

Drive ability is awesome... I can only dream of a newer motor that’s super smooth, pulls from 3-400 rpm, and never misses a beat... if it works, don’t break it. Why start from scratch when you’ve got such a good motor.

Tank5, if you go TB EFI, I would only consider 2 options ... Holley Sniper, or FiTech

Cheers

Whatever you choose, keep us updated!

 

[melvinjo]

Screw the FAST. Go with FI tech: Way less wiring, way easier to install, requires no fuel pressure regulator. I have had a FAST, FI Tech and E brock FI setups, and the FAST was the hardest to install, customer service zero, and it never ran correctly. To me, FI Tech has set a new standard in easy installation, ease of set up and ease of tuning

 

[Tank5]

The Holley Sniper has come up favorably several times. I am also looking into an edelbrock pro flo. Anyone have any experience with them?

 

[BrianSanDiego]

Yes, at least a couple of us are running a Sniper. There is quite a bit of info on it here...

Just read through that thread. Thanks for sharing it.
