Question & Answers

2 Answered questions

Q: I'm looking to covert my 2 barrel carb on my inline 6 cylinder4.2. would this be ideal for me and how hard is it to install. Answer this question

A: The best replacement would be the Holley Sniper EFI BBD for Jeep Part #550-858, this should bolt on to the existing intake. I would not recommend the 550-516 because the 4bbl will need to be laptop tuned. As far as installation, you should be fine as long as you follow the instructions and are mechanically inclined.
