On my 4160 holley my secondary jets is more of a plate and i'd like to switch over to jets that i can switch out. I'm looking forward to going to the track once it cools down to tune my car. any help would be great.
i have the holley conversion kit on my car, there are a few conpanies that make conversion kits, but the speed shop by my house had the holley kit. works nice and you dont have to deal with those plates anymore.
likw i said. there are other companies that make them. i jsut cant think of them off hand. a simple google search will tell you though. just search for holley 4150 conversion.
