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.
