Ok guys I know it's been a couple weeks and I've been extremely busy with work and car and getting race truck ready for our race in 3 weeks. Anyways I got engine in car and all bolted up and everything connected. Fired it up for first time took it a minute but it now idles pretty decent.
When I give it gas it pops like crazy. No ses light or anything. Good oil pressure opti is connected right and wires are ran right. Any ideas??

Please help me out guys
