1955-57 Big Block Chevy 396-502 Chassis Headers, Raw Finish

Classic Chevy owners will love these 396-502 big block V8 chassis headers for 1955-1957 cars. They have 34"-36" primary tubes for lots of power, but they're tucked close to the body for maximum ground clearance. Requires aftermarket side engine mounts and a rear trans crossmember (rather than stock bellhousing mounts).

• Mid-length design offers maximum ground clearance, even if car is lowered 4"
• Works with automatic transmissions only
• Designed to work with stock steering or 605 power steering box
• Original bellhousing frame mounts must be removed
• Will NOT work if engine is set forward more than 3/4" for firewall/HEI distributor clearance
• Will NOT fit tall-deck (truck) blocks
• Includes a pair of reducers (3.00" to 2.50")

Note: These headers will not work with manual transmissions due to clutch linkage issues.

1. Will not fit if engine is located more than 3/4” forward for HEI firewall clearance. Fits with TCI engine mount kit PN 725-7005-80 and with the equivalent Danchuk mounts.
2. Header is designed to fit cars using original V-8 pitman arm part number 3719487 not 6 cylinder pitman arm number 3709877. Aftermarket pitman arms must be same configuration as OE for proper header fit.
3. Works with A/C, P/B, P/S, and A/T (both column and floor shifters).
