link doesnt work



The 4150 has a secondary metering block, the 4160 is identical but it has a secondary metering plate instead of the metering block between the secondary bowl and the main body.

sorry about the link, but if you copy and past the text, it should work

Looks like a 600 vac secondary. Just get the Holly trick kit and rebuild it. You will also need to reduce the size of the idle air bleeds by about 50%.

Post up what mods are on this thing.

well, the carb has mechanical secondaries(i wouldn't doubt the previous owner(s) forcing vaccume to be mechanical). does that change what it is? i can take more pictures of the throttle linkage or anywhere if it helps identify it.



The car has the holley w/ a RB intake, as well as an RB street/strip exhaust, aftermarket plug wires, and msd blaster 2 coils....dlidfis on the way!



i'm planning on upgrading to duel inlet center hung float fuel bowls, holley part number 34-2. do i need the conversion kit or can i go to a junk yard and try to look for an old holley w/ the same bowls off another carb?

and what is a trick kit?

It is a kit that Holley offers that will cover a range of different carburators of the same series. It brings all the gaskets, O-rings needle and valve seat assemblies and much more. They retail for about $40.
