I am swapping my 307 in a 1986 Regal to A 1967 330 olds. The 330 has a Carter carb on it and ran great in the car. What is the best carb setup to use. I have a TH200C built by a race shop in the car now. Is it totally unfeasable to use the Qjet and computer? Not looking to drag just cruise with a little more power. Only drive it about 2,000 miles a year

Welcome to the group... It's may not be unfeasible to use the carb and computer, But if your state doesn't have issues with emission modifications, IMO, I would drop the computer and keep the basic 330 carb and distributor (or even go to an HEI)...

1988coreym

What about the tourqe converter lockup? We have no emissions inspections here.

IT would be more of a headache to put the CC quadrajet in.


However, you may need to for a certain extent. the TH200C has a throttle cable that set the pressures of the transmission and shift points. Make sure you know how to set this cable if connecting up to the carter somehow. To do it right, you'll need a pressure gauge and hose to read pressures... Or, bring it down to a trans shop and have them set it....


Your 307 likely has 7A heads. If it does, the ports are real small on the intake. You'll need another intake manifold to do it right. Look right on the humps where the exhaust ports go part the valve covers, you should see a 7A. By odd case you got a 307 HO motor, it still may have 5A heads, but will still have a roller cam....


The distributor is connected to a roller cam. Roller cams and flat tappet regular cams have different materials. The distributor cam gear will wear out quicker. You'll need an 81-85 distributor.


You'll need an 02 sensor bung on your current setup. The exhaust manifolds are smaller too on a 7a head 307.


Several aftermarket companies make lockup kits for atleast the 2004R, if not the TH200C. Or, not worry about it and leave it non lockup.....


For lock-up, you need a pressure switch to know it's in 3rd gear, and a switch to know if off idle and not hitting the pedal harder.


This is assuming the 330 engine isn't any different than swapping in a 350 olds..... Not sure about starters, oil filter locations, engine mounts, water hose connections, etc..........

The best carb to use with your 200C trans is either your CCC carb or a 76 to 80 350 or 403 Qjet. They both will be a bit lean for your 330, especially the 307's carb. The 76-80 800 cfm are the best Qjets and have the right linkage for your TV cable. What year is your 330? Does it have the stock intake? The early 330's came with the square bore 4GC carb. There is no lock up kit for the 200C. You either need to modify one or manually lock the converter if you remove the computer. Try the computer, just make sure everything is hooked up. Is your 330, high or low compression? The low compression version should work. The high compression version will not like 60 degrees part throttle timing that built into the 307's ECM.

Keep in mind that the secondary air valves on the 307 Qjet are limited to only about 70 degrees of opening. If you want to use this on the 330, you should file the stop so they open the full 90 degrees. And obviously if you choose to use a non-computer carb you also need to change the distributor.

It is The High compresion. Externaly the same as swaping a 350 olds in. I know alot of guys have done that. So just trying to figure out what the best options are. Do most guys just leave the Trans non lockup ? Or change to a Trans and if so which one. Just read a thread where a guy is puting in a 350 with an edelbrock to a TH2004R ?

olds 307 and 403

The 2004R trans is a nice upgrade if beefed up some. Were any upgrades done to your 200C? I would try a kit like the TCI lock up kit for the 2004R and add a big trans cooler. You need the Edelbrock geometry TV adapter and TV cable bracket for your AFB carb. Bowtie Overdrives have a great TV set up for the Edelbrock/AFB carb.

1988coreym

Yes the 200c was rebuilt in January and upgraded. However I have a TH350 out of a 77 Olds I can use if that would be a better easier option ?

sailinghudson25

IF you got stock rear end gears like 2.41, the 2004R will not like it. I forgot it either beats up the O/D clutches or the Lock-up in the converter. 3.08 bare minimum 3.23+ ideal.


LEave the 200C in there if it's rebuilt. Will handle it ok, maybe bump up the TV cable 1 notch higher for a bit more pressure and higher shift points.

joe_padavano

And yet, nearly every 200-4R came from the factory in cars with 2.73 or 2.41 rear gears.

I've owned four of them. The trans works fine. So long as the TV cable is properly adjusted, the trans kicks down from OD to third when speed drops going up a hill, and then it's no different than a TH350.

1988coreym

I am fine with the 200c if I knew how to deal with the Tourqe converter lockup?

olds 307 and 403

Try a kit like the TCI lockup kit. You replace the pressure switch and wiring and it has an adjustable vacuum switch to control when it locks up. I assume the 200C has the same style pressure switch and lock up solenoid as the 2004R/700R4 as that is what the kit is designed for. https://m.summitracing.com/parts/tci...bileSwitchYes#
Also add a big trans cooler and you will be good to go. Canadian cars actually had a vacuum lock up set up being non CCC. I wish, I knew this when I scrapped my 81 Delta 88 that came with a Olds307/TH250C factory. It even had factory plugs where the air injection tubes would go in the head.

I really like the 330 engine I think it is so over looked. I mean 320 horses factory is something. They run great and are an easy bolt in for later small blocks.

I am surprised more do not use them. I usually have 3 or 4 of them in good shape. I am looking for one of those late 70's early 80's 5.7 diesel trucks to put one in for a shop truck. would make a great parts hauler.

Thanks for the info guys ! Also what oil do yo run in your 330 ?

olds 307 and 403

The 330 is no doubt reliable and torquey like all Olds V8's. Being around for 4 years of production compared to 12 years for the gas 350 and another 5 years if you count the diesel version, is do doubt why less are found and used. The 350 has the ci advantage and slighty better breathing thanks to the larger bore. I can still find very good Olds 350 for cheap, my current 76 bottom has great oil pressure and compression. The 330 pistons are only available in cast for direct replacements. Yes, SBC 350 pistons and rods can be used in a stroker configuration. I believe the factory suggestion for the 307 was a 10w40, try some SL or lower rated oil.

??
mine has 3:73's

joe_padavano

I KNEW someone would go here...


The H/Os and 442s comprised a negligible amount of 200-4R production (as did the GNs with 3.42s), so I'll say it again: NEARLY all 200-4Rs came in cars with 2.73 or 2.41 gears.

midnightleadfoot

I guess having to subtract a few million units, is nearly eh..

joe_padavano

A "few million" what?

Apparently I need to spell this out explicitly. Probably 80-90% of the 200-4Rs ever built went into full size and intermediate cars with sub-3 ratio axles. The only 3.73s were in the 442, H/O, and Monte SS. The GNs got 3.42s. That production was far from "a few million" by a couple of orders of magnitude.

NEARLY all of the 200-4Rs went into B/C body cars with 2-something axles and G-body cars with V6s, 301s, 305s, and 307s - again with 2-something axles.

wr1970

I will say this. Joe p is more right than he is wrong. I would give him a 99% rating.

midnightleadfoot

not argue'n.. just can't see a full sized wagon with tow package with sub 3 gears..


When I think nearly.. it be all but a few.. Maybe my thinking of the term nearly is to blame..

joe_padavano

I'm afraid you'd be wrong. I have two 1980s B-body wagons with 307s and 200-4Rs. The steepest axle available was the 2.73.

olds 307 and 403

My 88 CSC was a 2004R with a 2.56 open, factory, codes on trunk lid proved it. The 3.08 rear was available but rarely selected, supposedly. Remember stock 307's had low compression, tiny cam and would have no problem at low rpms under load.
