10. Here is the LC Engineering EFI Pro/Street Performer cam. It has 0.440 intake and 0.440 exhaust lift and 230-degree duration @ 50. We have a set of LC Street Performer Valve Springs and retainers next the set of stainless steel valves to compliment it. All this will be turned by a LCE-modified timing chain cover and chain and guide kit. This converts the single chain and plastic guide setup to a double-row chain with metal-back guides to improve durability and reliability.
