Product Description



          1984-96 C4 CORVETTE
LS Swap "Smooth Flow" Headers

The C4 LS swap headers feature 1-3/4" primaries into a 3" slip fit collectors with stout 3/8" CNC cut flanges. O2 bungs located in each collector. Passenger side header maintains excellent clearance from the idler arm unlike so many other aftermarket headers. There is also plenty of room between the number 8 primary and the AC evaporator box. The collectors are intentionally angled in towards the center of the car since the exhaust must pass through the transmission crossmember. 

NOTE: THese will not work with the Corvette batwing oil pan and requires F-body pan and pickup tube.






Melrose customer Bob Wisniewski was one of our first customers to utilize the LSx swap headers on his 1992 Corvette. Bob recently ran a 10.04 @ 138.30 with the mods listed and should be in the 9's soon with his Procharger goals listed below.

Speedhound is a certified distributor for the Melrose Long tube swap headers.

Speedhound sells the LS motor adapter plates that allow the engine to bolt into the C4.

Quicktimeinc.com has a bell housing that puts a ZF behind the LSx engines. Part number RM 6039.

Vettaid.com has the dashes and other electrical areas covered. Harnesses are made by any number of people for the engine.

The LS motors need 58 PSI and the L98's and LT1's had about 43-45. Racetronix.com and their associated dealers has a drop in fuel pump for the car. This is the one we used for the 87 http://www.racetronix.com/RX-C4369-FPKG-2.html .

Dewitts has radiator avail thru Speedhound. The factory C4 radiator will work, but they weren't all that great from the factory, so an upgrade is recommended. Melrose will also contemplate offering a Howe radiator in the future.
