The Muscle Rods LSX16 kit mounts an LS engine and transmission in a 1958-1964 Chevy Impala, so it works as a 1963 Impala LS swap kit or for any year from 1958 to 1964. Choose the transmission you plan to run when you order, because the crossmembers are different for each. The kit is made in the USA.
What's in the kit
- Driver and passenger engine mounts
- Driver and passenger frame mounts
- Transmission crossmember
- Two outer crossmember frame brackets
- Polyurethane transmission mount, with spacers if needed
- Installation hardware pack
The frame mounts and transmission crossmember bolt into existing holes in the frame.
Transmission options
Order the kit for an LS paired with a T-56 or TR-6060, 4L60E to 4L70E, 4L80E or 4L85E, 6L80E to 10L90E, TH400, or Powerglide, TH350 or 4-speed.
Does my transmission need tunnel work?
- T-56, TR-6060, 6L80 and 6L90: yes. The install guide shows the tunnel split, opened and closed with a patch panel that fits under the stock carpet.
- T-56: a casting tab on the top driver's side is also cut off for tunnel clearance.
- 4L60E (700R4): little or no tunnel modification.
- Bodies, body mounts and frames vary, so some cars need the tunnel or firewall clearanced.
Which oil pan works?
The kit is designed for the GM 1998-2002 F-body oil pan.
Headers, A/C and accessories
- The 1998-2002 Camaro and Firebird F-body alternator and power steering work with the kit.
- For A/C, the Muscle Rods high-mount A/C compressor is needed.
- The factory clutch Z-bar will not work. A hydraulic clutch is recommended.
- Driveshaft length changes from original.
- Designed around factory suspension and steering components.
