Is there a way to determine which injectors the previous owner installed on my truck. He said they are larger, but i would like to know which size they are and who makes them so when i go to replace them i know what size i was runnin before. With the drag comp and WH1C i can lay down some heavy smoke and EGTs climb quickly. Any advice would be appreciated.

 

I'm afraid that without records, you will have a hard time figuring that out. The only suggestion I have is, if the tips are 7-hole cone-shaped, most likely Jammers. If the tips are dome-shaped (like a hemisphere), they could be Machs (unlikely, the PO would have asked for a premium for you to keep them; at nearly $1k, they are too expensive to just "throw in" with the truck).
