302-3 Retro-Fit Oil Pan LS Swap Replacement - Increased Capacity

Our review of the 302-3 RetroFit Oil Pan finds it is a practical, no-nonsense replacement for builders installing an LS series engine into classic GM and Mustang platforms. The bottom line: this oil pan is for the owner or shop needing a fitment-focused solution that increases sump capacity and maintains compatibility with common LS oil filters. Installation and fit receive praise for alignment and appearance, while a few users note mixed experiences with installation time and bolt hole alignment, so some patience and checking of dipstick tube fitment are advised.

Key Features

• Wide vehicle compatibility: Fits many GM swap applications including 1967-1969 and 1982-1992 Camaro/Firebird and 1979-2004 Mustang, simplifying LS conversions across classic platforms.
• Increased oil capacity: The sump holds 5.6 quarts and the total capacity with a stock oil filter is 6.1 quarts, providing improved oiling and cooling over some stock pans.
• Oil filter flexibility: Works with AC Delco PF48 or PF48E, Mobile M1-113, Wix 57060, HP-1017 and equivalent filters for easy sourcing and serviceability.
• Stroke clearance: Accommodates a maximum crankshaft stroke of 4.00 in, giving room for a range of build choices without modification to the pan.
• Dipstick recommendation: Requires Holley 302-15 dipstick and tube kit or LS3 dipstick and tube parts for accurate oil level checks, which avoids guessing after installation.

Who It's For

This oil pan is aimed at enthusiasts and professional installers doing an LS swap into classic A-body, F-body, G-body and later Mustang chassis who want a pan designed for those applications rather than adapting a factory LS pan. It suits builds that need extra sump capacity and reliable filter compatibility without extensive fabrication.

Those who should look elsewhere include owners who require a pan with integrated baffling for high-G motorsport use or vehicles with extreme ground clearance concerns; a dedicated race pan or custom solution may be preferable in those cases.

Pros & Cons

Pros

• Good fit and finish for common swap installations, with several customers reporting the pan "fits perfectly" and "looks good".
• Increased sump and overall oil capacity improve lubrication and cooling for street and mild performance engines.
• Compatibility with widely available oil filters makes maintenance straightforward.
• Clearance for up to 4.00 in crankshaft stroke supports many stroked small-block builds.

Cons

• Some customers reported mixed experiences with installation time and bolt hole alignment, so expect to verify alignment and possibly adjust during fitment.
• Requires specific dipstick and tube kits (Holley 302-15 or LS3 parts) which adds a small additional purchase for proper oil level checks.

Specifications
