Holley carb opinion Printed From: CorrectCraftFan.com Category: General Correct Craft Discussion Forum Name: General Discussion Forum Discription: Anything Correct Craft URL: http://www.CorrectCraftFan.com/forum/forum_posts.asp?TID=48518 Printed Date: March-06-2025 at 7:57am Topic: Holley carb opinion Posted By: mmfarmer1 Subject: Holley carb opinion Date Posted: April-08-2020 at 12:37pm I've got 2 spare Holley carbs that I'm about to rebuild. A 600 CFM and A 650 CFM. The 650 is in MUCH better condition than the 600. I'm currently running a Holley 4160 600 CFM on my 76 Ski Nautique with a 351W.. I've never run a 650 and was wondering how much of a difference, if any?? Thanks. Replies: Posted By: TRBenj Date Posted: April-08-2020 at 12:42pm I wouldn’t expect much if any difference. The 600cfm is plenty for a 351w and is what came on them. The 650 was used on the 330hp 454- suspect you could find a buyer for it if you wanted to sell. It should have the vacuum port (towards the front) as that’s where PCM plumbed the PCV.
