ArdWrknTrk Posted May 3, 2021 Share Posted May 3, 2021 I used the same carburetor Jim mentioned. It hooked right up to my linkage, I have an automatic transmission. https://www.holley.com/products/fuel_systems/carburetors/street/parts/0-80457S They also offer a 0-80453 I do not know what the difference is. I do know the 80457s doesn't have the dichromate finish and is $200 less. Link to comment Share on other sites More sharing options...

Hi Jim. Or somebody else who knows Do somebody have the part number for the Motorcraft gasket under the EGR plate on my 351W 1986 ? And is there somebody who have actually mounted a Holley 4160 , specify which model, on the 1986 351W ? Link to comment Share on other sites More sharing options...

The 460's started using a pink polymer gasket to avoid the blowouts common with the laminated metal ones. The 351 EGR plate port is square instead of the 'ear' on a 460.

Keep on peeling layers off this onion.... Have not ordered new carburetor yet. Cant decide on which. There is also packages with carburetor and intake manifold. I wouldnt mind getting rid of the EGR system. Will a non egr manifold be compatible with my engine ? Holley sells carburetor with Weiand Stealth intake. I have also learned that the timed vacuum shall be 0 at idle.Not so with my old 4180C. This weekend I decided to pull the transmission off. To fix the oil leak at the back of the engine. Oil must out, all oil pipes, mechanical connections, exhaust, transfer case, crossmember, .. A motorcycle jack is nice when you are working on the ground. The oil seal on the crankshaft was leaking. Replaced it with a new from Timken. I used the old seal to get the new knocked in.New seal No traces of leaks elsewere. Incidents ? The six bolts that held the "flywheel" were very hard to get loose. Exept one. The head fell off with almost no resistance when I tried to screw the bolt out. Somebody must have been to hard when they mounted this back on. Will try to find 6 new bolts. They probably changed the seal on the crankshaft. If you look at the photos you can probably tell if the old seal is original or not. Converter, new or old ? Flywheel.AluplateOld seal and broken bolt in crankshaft.Removed the piping for the smog pump. Thought about how to block the hole. Then I saw the hole was treaded.A bolt with diameter 15,6mm fits, 0,615" .11 threads per inch.( or 12, not sure how you count them ). Well, enough for now Link to comment Share on other sites More sharing options...

Well, enough for now Yes, Ford does not use ported vacuum for these DSII distributors. If you have a vacuum diagram on the radiator support you will see manifold vacuum goes to the thermal vacuum valve, and then through a vacuum restriction (or if overheating, directly to the distributor) The thermactor ports in the back of the heads are tapped 5/8-11 NC.

Made me tired just reading it. Changing the rear seal in the truck is a huge pain. I've not done it on a 460, but have a on a 351W and vowed to never do it again. So I'm in awe that you got it done. A non-EGR intake will be compatible with your engine. But, the distributor was tuned to give a lot more advance than one w/o EGR due to the inert gas which slows combustion and needs an early spark. That was probably done via the vacuum advance since it is when vacuum is high that they introduce the exhaust gas. But since you turned the adjustment all the way to the other end in the vacuum advance unit you may be well positioned to run w/o EGR. Link to comment Share on other sites More sharing options...

The split/rope seal for a 460 is 'challenging' when you can't get the pan off to drop the crank. That looks like a 1 piece seal to me. Link to comment Share on other sites More sharing options...

Yes, it certainly does! Interesting. When did the 460 go to that? Link to comment Share on other sites More sharing options...
