Im looking for a bigger carb for my 400ci. and the wee 600cfm isnt cuttin it so well.
This Holley 600cfm carb is a 4160 vac. secondary. It has side hung bowls. I rebuilt it 2 yrs ago. It will start the ol engine with to good flicks of the pedal. It is just begining to leak on the accel. pump diaph.
If no one wants to trade for a 750…
Im looking for a Holley 750cfm car. VAC. secondaries, gotta still have the choke horn (since this is for my winter car). I can rebuild it so, if its been laying in the corner of the garage its fine. I know ~most~ of the numbers but, I got a book for reference as well. So, if u “think” u got one u wanna get rid of.
Lemmie know if anyone has on laying around.
Thanks!

A guy i work with has this:
[http://store.summitracing.com/partdetail.asp?autofilter=1&part=HLY-0-4779C&N=700+4294925239+4294839063+4294919007+115&autoview=sku](http://store.summitracing.com/partdetail.asp?autofilter=1&part=HLY%2D0%2D4779C&N=700+4294925239+4294839063+4294919007+115&autoview=sku)
it’s new, never used, but one of the lower mounting bolt holes cracked off, but he still has the part that broke off.
I will get back to you on monday, if you’re interested. He’d let it go real cheap.

^^^That one in the link is mech. secondaries…I want vac. If is IS vacuum secondaries…lemmie know.
Thanks for all the replies…but, Im stuck on just wanting the 750cfm (even though I just realized I put, “740cfm” in my title. :rolleyes:
Its a real mild 400ci engine that this is going on.
