Which Holley Carb?

Thanks for the comments on the engine...it is appreciated. Alot of sweat and tears for the last year or so getting the engine put together. I should post up some new pics of the boat. Since those pics were taken I now have changed over to a demon carb and had to custom make a new fuel line. I also changed all of my fuel line fittings over to AN style which is the 37 degree fittings and I like them better because you don't have to use any tape or pipe dope to get them to seal. Even though Holley states to not use any tape on the fuel fittings I have had standard fittings leak and called Holley tech and they even said in some cases you may have to use tape or that ARP pipe dope that is fuel resistant to stop stubborn leaks on standard fittings. Anyway the AN fittings are easy to undo if you are tuning the carb alot and need to take it off they are easier to use.

Those DUI plug wires do look cool but I had about six or seven of the metal inside the cap that snaps on the spark plug just break off onto the spark plug doing plug checks while tuning the carb. I could only take them off about two/three times and they would break off. DUI was good about sending me a replacement piece but I got tired off always worrying if one of the cyclinders was not getting a good spark due to one of the plugs not getting fire. I just replaced them with those high energy Moroso blue wires and so far they have not broken off yet. Maybe if you just installed the DUI wires and did not take them on/off as much as I did they would hold up better.

Thanks!

That is one heck of an engine. What kind of ignition wires are those? They look like they have braided insulation on them.

Jim is she a "ONE BAGGER or TWO BAGGER????











one bagger = one bag fits over her head
Two bagger= one bag for her, and one bag for you...........

Wow, that is one beautiful engine!

Vic: Could you post some pics or try to e-mail me some?

Thanks;

I appreciate the offer, JR, and I'm sure it's a beautiful carb, but it sounds too complex for me right now.

It will be a chore just to rebuild the stock 4160 correctly, put it back on the boat, and get it dialed in. I also plan to replace a bunch of water hoses, clamps, fuel hoses, belts, etc., restore the shine to the boat's gelcoat, and get some skiing in, too.

What do you mean by make sure the butterfly valves are "nice and tight"? On the shafts? In the barrels?

I ordered a new choke stat. Good idea.

The extra part you mentioned is the secondary diaphragm assembly, I believe. Doesn't come with the kit. Ordered one of those, too.

Thanks for your continuing assistance.

Thanks, fellas. The rebuild kit came with a 2.5" PV. I'll plan to go with the standard 6.5" PV. If it doesn't work properly (and I believe it will), I can always install the 2.5" PV.

The carb was new in 1995, rebuilt in 1998, and hasn't been touched since. I can't wait to get it running perfectly again!

I have 1996 SN with same engine.
I ordered a 4160 a couple of months ago from Skidim. Replaced the old carb and engine run really great now! Didnt need to adjust anything except from the idle of course.

Be aware that Summit has a lot of different types of the 4160.
You should have the 4160 600CFM 4BBL for this Ford engine.

OK, I think I'll try rebuilding the old carb myself (assuming it's not corroded on the inside) and install the 6.5" PV. There are lots of helpful tips on this site as well as on the Holley site, so it should be do-able.

The Summit Racing site lists a couple of Holley 6.5" PVs. One is a standard flow. The other is a high flow. Which one would you go with?

Thanks for any additional advice on this.

PV is on the primaries, isnt it? How would it affect the secondaries?

where are you located? you want the first one notice the location of the fuel line as it is attached to the carb. They are basicly the same carb.

As for the powervalve if it doesn't come with the 6.5 them it will have a smaller vaccum rating and the secondaries will come in later, not a bad thing for fuel consumption, but might hurt out of the hole or pulling perfromance.

why don't you just re-build the one you have now
