Speed Engineering LT Swap 1 3/4" Shorty Headers - Camaro, Chevelle, Nova, C10/K10 & OBS
Speed Engineering 25-1270 natural 304 stainless-steel LT swap shorty headers use 1 3/4-inch primaries, 3-inch V-band collectors, merge spikes and port-matched flanges for Gen V LT1/LT4/L8T/L8P swaps.
Includes manufacturer-supplied graphite gaskets and installation hardware.
SMG recommended upgrades: Choose our vehicle-correct SMG LT MLS gasket set and/or add SMG 9070C Ceramic Plug Wires. The ceramic boots resist header heat and melting; these are the only plug wires we use on our in-house header builds.
Applications include 1960s-1970s Camaro/Firebird, 1968-74 Nova, 1968-72 Chevelle, 1960-87 Chevrolet/GMC C10 and K10 trucks, and 1989-99 C1500/K1500 trucks. Verify swap-specific steering and transmission clearance.
Processing & Shipping Overview
Processing occurs before shipping.
Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.
Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.
For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
