Today I picked up a fairly sound running and driving 1992 S-10. It's a bit ugly but it's mechanically sound. I plan on using it as a beater truck but my mind got the best of me as I was going over it making a list of things to do to it.

It has the little 4 banger and a 5 speed manual transmission. It's fairly zippy and kind of fun to drive. Then the small block conversion entered my mind. Living in california I would be subject to smog checks every other year so it would be best to convert it to a small block in a way that could easily be returned to the original 4 cylinder when needed.

If I did end up doing the conversion it would be using a very stockish small block. Something like a cheapo 190hp 350 crate motor. I have a 2014 Camaro ss for having fun. Just thinking about it because I think it would be a little more fun than the 4 cylinder.

My real question is the factory s10 manual transmission? I'm not sure if the bell housing is compatible with a small block or not. The plan would to be just a simple engine swap. I don't plan to beat on it hard or use sticky tires.

I'd be curious on the thoughts of doing this?

You can use a bell housing adapter. What's the gear box ID? Being a manual, a swap back would be easy with planning. Make hose connections into quick connects. Mostly coolant hoses. You probably don't need heater core connections. No transmission oil lines either. The electrical is easy too. Power to the distributor, starter, and battery. Grounds can be swapped easy. Does it have power steering? Which side is the alternator side on? GM moved them to different side overs the years. Install a belt routing with the alternator on same side as the 4 banger. With good planning, you could probably swap back and forth in a day or less.

I'm not sure what gear box is in it. It looks like possibly could be two or three different ones used from what I've read. I just got it yesterday after noon and haven't had any time to really dig into it.

Alternator is on the passenger side. No power steering either. It's so simple it's funny. Stripped down model for sure. I don't need a heater and there isn't ac.

I was thinking if I do a swap I would likely put a fuel cell in the bed so the original fuel system could be left intact. Seal it up and kill the power to the pump. Run either a mechanical pump or add in separate electric pump for the v8.

The previous owner just put a new exhaust manifold, new pipe and cat no muffler. Probably very easy to remove and replace when needed.

It's funny after having two LUV trucks with small blocks this idea never occurred to me until I got it home. I started thinking if I could adapt a small block to the original transmission it would be a fairly easy swap in a weekend once I had everything together.

The other option is to find a small block tbi truck setup and jump through the ca emissions hoops. It would probably be more trouble and time than it would be worth.

Does it have RPO codes somewhere? The codes should ID the manual box. Vortec FI engines had the alternators on the same side. Brackets and accessories would fit for quick disconnect.

I'm going to have to check to see if I can find the RPO codes. It's been a busy weekend hopefully I will have a chance before the sun goes down.

I did find the RPO codes. Now I just need to do some research.

Found a MW1 on the codes which I translated from another website as a borg warner 5 speed. Other than that I'm still not exactly sure.

A quick search indicates it's only mated to I4 and 60 degree V6s. It won't fit a 90 degree V6 or small block.

I live in CA as well.

Swapping engines in and out every 18 months is a PITA. I have a friend that has to swap out just the induction system of his Buick GN and even that's a PITA.

I think it would be worth your time to investigate other alternatives.

Engine changes in CA have been successfully done in the past. Once you get the referee label you're home free.

I was talking with a co worker today that had a newer S10 than mine. His was 4 wheel drive and had the 4.3. He is not mechanically inclined at all but he had a manual transmission that he had to have rebuilt.

I asked him what transmission was in his and he said it was a NV3500. He probably really doesn't know but that's what he rattled off.

I haven't had any time to do any research today. In theory if I could find a NV3500 I would imagine it would be a fairly straightforward swap along with a small block.

I will read the link posted above. If I can manage to do a legal swap I think that would be cool. I think it could also improve the resale value if I ever decided I wanted to sell it.

I don't have any experience with a tbi setup but I would imagine it would be much easier than a vortec 350 dealing with the electronic part anyway.

"The NV3500 is manufactured for both four-wheel drive and two-wheel drive vehicles. The current NV3500 is found in full size GM trucks from 1988 and newer, S10 trucks from 1990 and newer, and Dodge Dakota V8 Ram trucks from 1994 and newer. The NV3500 is a five-speed manual transmission."
An aftermarket bolt on TBI would be helpful. If programmable, it can run both the 4 banger and SB. A 4.3 swap wouldn't be so bad either. Smaller, lighter, and compatible.

Thanks for transmission info. Pretty sure for a legal engine change that I will be required to use factory parts or CARB approved after market. Pretty sure the new engine and everything on it has to be same model year or newer than what body it's being installed in.

Cali suxs!!

When I bought my truck, it was grandfathered. The first thing cut off was the catalyst converter. After that, all the emission hoses I could find.

LoL I know california sux. One of my co workers used to own his own smog shop. He also has a ton of cars and trucks from when he had a towing business. I will have to check with him for advice and see if he has donor truck sitting around.

I was sent home yesterday from work due to being exposed to covid. I was tested and my results came back negative. I am waiting to hear how long I will be stuck at home. If it's going to be a while I am planning on getting on the body and paint work to keep myself busy.

Breathing the dirty air that is produced by the 15 million motor vehicles on the roads here and spending your golden years lugging a oxygen tank around with you sux even worse.

If you would stop huffing nitro you would probably be in better shape. *Edit that was a joke. Hopefully everyone got that*.

In all seriousness though I think a good running V8 in something that isn't daily driven isn't going to hurt anyone or anything.

I talked to my buddy the ex smog man and he said eff the referee do what you want and change it back every two years. He gave me specific examples that were so stupid it's not funny about doing engine changes in Kalifornia.

I'm thinking about trading in the ss camaro for a truck and making this my new hot rod project.

So on the topic of passing the sniffer. The 2.5 failed as a stock motor. The idle was 1000 rpm and max allowable is 800rpm. I replaced the IAC sensor hoping it would be the quick fix. This truck doesn't have a tachometer and the fact it didn't have a muffler was a bit deceiving.

I had a feeling it was idling a bit high. I was right and it failed for that reason. In ca it is the responsibility of the seller to have a smog cert up to 90 days before the transfer or during the selling transaction. My bad I should have had a cert in hand when the purchase happened.

After going round after round with the po I stated the section in the vehicle code book stating what I just said. He got a little irritated with me and I told him he had two choices. 1 get the truck to pass the emissions test or 2 give me my money back and come get the truck.

I was hoping he would be cool and do his part but he cried about it and said he would give me my money back and get the truck. He came with a bad attitude and a fist of $100 dollar bills. So now I'm officially S-10less.

Too bad he tried to pull one over on me. I was really looking forward to building this truck. Now it's back for sale on FB at a lower price stated being sold as is. Being sold as is doesn't exempt him from having to smog this thing. So hopefully the next owner is as nice as I was.

It sucks that the seller was deceitful by omission in not telling you that the sale was "as-is".

I've heard of instances where the seller gives full disclosure to the buyer regarding a vehicle's inability to pass smog inspection and the sale is dependent upon the buyer acknowledging this and being responsible for the smog inspection.

You can check a vehicle's smog history here:

https://www.bar.ca.gov/services/Vehicle/PubT stQry....

When I come across an interesting item for sale, I go to the above link and do a quick check. If there's no history, a history of fails or the inspection history suddenly stops 2-3 years ago, these are red flags which require further questioning of the seller if I'm still interested (not usually).
