    Default ZZ383 with Avenger 550-400??

    Hi. I have a 550-400 on my present ZZZ350 and it works great. I am thinking of swapping my ZZZ350 for a ZZ383. Can I use the 550-400 straight off on the ZZ383 or do I need any modifications done on the Avenger system?

    Yes, the Avenger 550-400 will function fine on the 383" engine (if the only change is 33 cubic inches).
    However, the 383" engine would benefit more from the Avenger 550-401 (900 cfm).
