modifying the carb for boost

[200cid]

i remember looking at a web-site about preparing holleys for boost but can´t remember the address.. could someone throw in something usefull?
(the carb is holley 2300, 350cfm two-barrel)

youll need a power valve based on the vacuum your making and a nitrophyl float, I also milled off the choke horn. you should look into buying the holley carb supertuning and modifying book, its pretty helpful.

You would also need those plastic type Holly floats so it will not collaspe under boost pressure.

Brass ones will collaspe. 8)

pretty simple. there are a couple vac ports on the choke side you plug when you remove the choke from the carb and swap the float out. you can mill the choke horn but it is not needed (but nice)
