Swapping an LS engine into a G Body (Monte Carlo, Malibu, Regal, etc.) requires an oil pan that clears the steering linkage, crossmember, and frame rails. We researched manufacturer specifications, industry fitment standards, and aggregated owner feedback to evaluate the top options. Our comparison covers capacity, construction, baffling, and clearance to help you choose the right pan for your build.

1. Holley 302-1 Oil Pan: Best Overall
We researched the Holley 302-1 extensively and found it to be the most popular choice among G Body LS swappers. Its cast aluminum construction is robust, and the internal baffling helps prevent oil starvation during hard cornering. The included windage tray and pickup tube simplify installation, and owner feedback confirms it clears the steering linkage and crossmember without modification.
However, the price is higher than some steel options, and it may not fit all aftermarket K-members. If you have a stock or modified K-member, verify clearance before purchasing. For those on a budget or with a highly modified chassis, consider the ICT Billet or stock pan options.
- Designed specifically for G Body LS swaps with steering linkage clearance
- Cast aluminum construction with internal baffling for oil control
- Includes windage tray and pickup tube for a complete solution
Pros: Excellent fitment on G Body chassis; High-quality casting with good oil control
Cons: Premium price point
2. ICT Billet 551609 Oil Pan: Best Value
We compared the ICT Billet 551609 against more expensive options and found it offers excellent value. The steel construction is sturdy, and the powder-coat finish holds up well. Owner feedback consistently praises the fitment on G Bodies, with many noting it clears the steering rack and frame rails without issues. The included pickup and dipstick are a nice bonus.
However, steel pans can dent if you bottom out, and the oil control isn’t as refined as a cast aluminum pan with deep baffles. If you track your car or need maximum oil control, the Holley or Improved Racing pans are better choices. For street and occasional autocross, this is a solid pick.
- Affordable steel pan designed for G Body LS swaps
- Includes pickup tube and dipstick
- Powder-coated finish resists corrosion
Pros: Great value for the price; Good clearance reported by owners
Cons: Steel can dent more easily than aluminum
3. Improved Racing 1060 Oil Pan: Best Baffled
In our evaluation, the Improved Racing 1060 stands out for its advanced trap door baffle system, which prevents oil starvation during hard braking and cornering. The cast aluminum construction is lightweight and durable. Owner feedback indicates it fits most G Bodies, but some report needing minor frame notch for the deep sump on certain years.
This pan is overkill for a daily driver and the price reflects its racing pedigree. If you never track your car, the extra cost and potential fitment hassle aren’t justified. For serious autocross or road racing, it’s a top contender.
- Trap door baffling for superior oil control under high G-forces
- Cast aluminum with deep sump for increased capacity
- Designed for LS swaps with steering clearance
Pros: Excellent oil control for track use; High capacity
Cons: Higher price; May require notching frame on some G Bodies
4. GM Genuine Parts 12551353 Oil Pan: OEM Fit
We researched the GM 12551353 as a budget-friendly option. It’s the stock pan from an F-body and can be made to work in a G Body with a custom pickup and possibly notching the crossmember. Owner feedback confirms it’s a common route for low-budget swaps, but the fitment is not bolt-in.
This pan lacks baffling and has a lower capacity, making it unsuitable for performance driving. If you’re building a budget cruiser and don’t mind fabrication, it can save money. Most builders will prefer a dedicated swap pan for easier installation and better oil control.
- Factory GM part from 1998-2002 F-body Camaro/Firebird
- Stamped steel construction, reliable and affordable
- Commonly used in LS swaps with modifications
Pros: Very affordable; Readily available
Cons: Requires modifications for G Body clearance; No baffling for performance driving
5. Melling 4.8L 5.3L 6.0L Oil Pan: Budget Pick
We evaluated the Melling truck-style pan as a budget option, but it’s not ideal for G Body swaps. The front sump design often interferes with the steering linkage, and the shallow depth can cause oil starvation. Owner feedback is mixed, with many reporting they had to cut and weld to make it fit.
This pan is best left for truck applications. For a G Body, the extra effort and potential reliability issues make it a poor choice. We recommend spending a bit more on a dedicated swap pan.
- Low-cost replacement for truck LS engines
- Stamped steel with simple design
- May require modifications for G Body clearance
Pros: Extremely affordable; Good for truck engine rebuilds
Cons: Poor fitment for G Body LS swaps; No baffling or windage tray
6. Moroso 20190 Oil Pan: Racing Oriented
We researched the Moroso 20190 and found it’s a popular choice for high-performance LS swaps. The stepped sump provides extra capacity while maintaining clearance for the steering. Owner feedback notes that it fits most G Bodies, but some had to trim the crossmember slightly. The baffling is effective for track use.
However, the price is high, and for street-driven cars, the extra capacity is unnecessary. If you’re building a weekend warrior or track car, it’s a strong option, but daily drivers can save money with the Holley or ICT Billet.
- Stepped sump design for increased capacity and clearance
- Cast aluminum with internal baffling
- Includes windage tray and pickup
Pros: High capacity and good oil control; Durable construction
Cons: Expensive; Fitment may require minor modifications
7. JEGS 300-5555 Oil Pan: Entry Level
We compared the JEGS 300-5555 to the ICT Billet and found it similar in design and price. Owner feedback indicates it fits most G Bodies with minor adjustments, and the included pickup is convenient. The powder coating is decent but can chip over time.
This pan is a solid entry-level choice, but the baffling is minimal. For aggressive driving, oil starvation can occur. If you’re on a tight budget and drive conservatively, it works. Otherwise, spend a little more on the ICT Billet for better quality.
- Affordable steel pan for LS swaps
- Includes pickup tube and dipstick
- Designed to clear steering linkage
Pros: Good value; Decent clearance reported
Cons: Steel construction can rust if coating chips; Oil control adequate but not great
Frequently Asked Questions
Will a stock LS oil pan fit a G Body?
Most stock LS oil pans (from trucks, F-bodies, etc.) do not fit G Bodies without modifications. The steering linkage, crossmember, and frame rails often interfere. Dedicated swap pans like the Holley 302-1 or ICT Billet are designed to clear these components.
What oil pan capacity is best for a G Body LS swap?
For street driving, 5-6 quarts is sufficient. For track use, consider 7 quarts or more to prevent starvation. However, larger pans may require frame notching or have clearance issues.
Do I need a windage tray or baffling?
For daily driving, a stock pan without baffling may work, but for performance driving, baffling and a windage tray help prevent oil starvation and reduce parasitic drag. Pans like the Holley and Improved Racing include these features.
Can I use a truck LS oil pan on a G Body?
Truck pans have a front sump that typically hits the steering linkage. They are not recommended. A rear sump or dedicated swap pan is required for proper clearance.
What pickup tube do I need for a swap pan?
Each oil pan requires a specific pickup tube. Most aftermarket swap pans include a pickup, but if not, ensure you match the pan’s depth and mounting location. Using the wrong pickup can cause oil starvation.
Our Verdict
After comparing fitment, capacity, construction, and owner feedback, the Holley 302-1 is our top pick for its excellent G Body clearance, robust construction, and included components. For budget-conscious builders, the ICT Billet 551609 offers great value with reliable fitment and performance.
