A-Body LS swap fitment notes

The kit is designed around a high-clearance oil pan that sits flush with the front crossmember and clears the steering center link tie rod ends. An LH8 pan hangs about 1.5 inches lower.
4L60E, 4L65E, 4L70E, 4L75E and 4L80E automatics fit the factory tunnel as is.
T-56, TR6060, 6L80E, 6L90E and 8L90E need the tunnel opened and widened, then closed with a filler panel.
High-mount A/C and alternator brackets are required to clear the frame.
When ordering, give year, make, model, body style (convertible or hardtop) and transmission. Crossmembers vary by type.
Headers suit a floor shifter. Column shift cars need linkage changes or a cable shifter.
Header installs may need the starter, valve covers or spark plugs removed.
The factory clutch Z-bar will not work with these kits, and the driveshaft may need a new length.

1968-1972 Chevelle, El Camino, GTO and Tempest, Cutlass and 442, and Skylark.

Which oil pan works with the A-Body kit?

A high-clearance pan. It sits flush with the front crossmember and is needed to clear the steering center link tie rod ends. The Moroso High Clearance and Cast Aluminum Retro pans are listed on this page.

Do I have to cut the transmission tunnel?

Not with a 4L60E, 4L65E, 4L70E, 4L75E or 4L80E. A T-56, TR6060, 6L80E, 6L90E or 8L90E needs the tunnel opened and a filler panel. The install guide shows where to cut.

Which fuel tank should I pick?

Choose the tank listed for your model and years. Notched tanks add exhaust and tire clearance. The 255 LPH pump supports up to 550 hp, and the 400 LPH pump is for more power.
