Questions & Answers

Does this engine also come with the balancer and fuel pump? Kind of hard to determine based on the specs provided because they also mention headers. As Ppridgen asks, the real question is does it come as pictured?

Asked by: Aegis43
Yes, the fuel pump and balancer are included, and listed in the Specifications, with those manufacturers, and their part numbers. No headers are included.
