My brother-in-law just handed me a 4bbl Holley Carb, and a rebuild kit for it. The kit was opened, so I'm not 100% sure everything is there Also, I'm having trouble finding information about this carb. I checked out holley.com and it wasn't listed, so I e-mailed them. They say it's a 4160 series off a '77 Ford "service vehicle" that had a 460 engine. The list# is 8418.
The throttle linkage doesn't come back when you trigger it, so I probably need new springs. It has a Ford Motorcraft electric choke on it. I own a '76 Chevy Malibu that had the stock 305 w/ a Rochester 2bbl. Not sure if I can use the electric choke. Dad seems to think that it just needs a 12v power source to work.
It has a vaccuum secondary. I have no idea what cfm it's rated for, but I imagine it's more than adequate for my little 305 if it was powering a 460.
Is it worth converting to a 4150? Also, should I invest in one of those power valve check ball kits, so a backfire doesn't risk ruining my power valve. Do I need to convert it to a manual choke?
Also, there is a slew of extra vaccuum ports on this thing. I can get pictures if necessary.
I'm just looking to get my 305 running a bit more reliably and the linkages on my 2bbl are shot and I can't seem to find replacements anywhere, so I picked up a 4bbl manifold and had my eye out for a 4bbl when my brother-in-law said he had one he'd give me.
It's a squarebore, with a fuel transfer tube. That's about all I know about it.
I need to know if I should invest in any of these kits, or just try to rebuild it and tune it as it is. I'm looking for reliability more than performance. Right now my car gets 'bogged down' and wants to stall if I take off too fast. Also, the choke linkage is screwed and I can't start the car unless I hold my foot on the gas a bit, otherwise it just floods.
If anyone has any opinions, information about this carb, etc. I'm open to suggestions. I know the 4150 and 4160 carbs are about the two most common carbs the aftermarket supports, so obviously parts, and literature isn't unavailable, but I can't seem to find a definate specific diagram of the 8418 list. I will especially need help with the vaccum ports, and several of the springs appear to need replaced in the linkages.
Thanks,
Mathius
