I'm in the middle of a 4.3 to 5.3 swap in an 01 regular cab. Just ordered prc 2.5 heads and 228r cam and lt's from Texas speed. They mentioned to get some 8.1 truck injectors. I've found them on eBay I think but is there a part number for them so I can verify?

Also, what's the best upgrade fuel pump that literally is just a drop in in the factory tank?

 

Any help?
