You're not going to want to remember. It'll be a night and day difference.


On mine, since it was used, the previous owner had screwed in some vacuum ports. This picture wasn't directed at them, so they're almost off-camera, but should be visible.


One was just a big one for the brake booster, and the other one had multiple sized ports for whatever reasons. I didn't use all but one or two, so I capped them off. I have no clue where to get them since I've never looked, but can't imagine they're not readily available.

 

JB weld work ok?


thanks

 

I used one port for the brake vacuum line and plugged the other one with a screw in plug. Put some thread tape on it to help seal it up. Can get those plugs with the Allen head on them at most hardware stores.

 

cheer's guys for the info

ups stoped by a bit ago as well


scored a engine host and stand off Craig's list for 200 for the project as well


top of the day to you all

 

AB or coolguy, would one of you be so kind as too grab this piccy and draw on it with paint and show me what all will need filled in with the JB weld, just want to make sure I do it right.

also we are looking at the manifold side right?

and what would be the best gasket setup, 4 hole for both sides?

thanks for any/all help folks

 

It'd just be this area here:



All of the area to the left of the dotted line is exposed to atmosphere, so if it's not covered, that entire opening is a vacuum leak. Plus, the opening on the end of the nozzle needs to be filled.

The side in the picture does go towards the manifold, and definitely use gaskets with individual runners. If not, you'll have air/fuel mixture mixing between the upper and lower runners in the intake.

 

Thank you sir what made me ask on the part to fill is because I didn't know If I should block off the channel to the right side of your shaded in area between the 2 chambers on the left side

Now that I think about it the first plate you used before the heated spacer could not have blocked those off.


cheers and thanks for your help and info

 

Hrmm...not sure on that one. That part isn't covered on mine. Maybe it doesn't make a difference because they're both secondaries? (at least on mine) The parts I colored in were only thinking about the vacuum leak.

However, if you can fill it, and do a quality job of it, I'd say it's a good idea since it won't leave it up to question if it has any ill effects. Maybe since mine's off right now, I'll try filling that gap and see if it makes a difference.

 

from your youtube vid I would say your's ran fine that way.... but you have posted about low MPG on road trips? hmmm

I dont know how the carb system's worked back in those days but prob nothing like today.

wonder if Holley tech support can be of any help, and I bet the machine shop could be of some help to make sure it got done proper

 

On mine I just used the fast weld putty and filled just to the right of AB's line. The gasket covered and sealed the rest. Just needed to seal off that area so the gasket will seal over it.

 

thank you sir for your input.... I did go out and line the gasket up for a better view of things.... all makes since to me now

got my EFI exhaust in today as well as a weather strip'n kit for the F250

can see some globs of slag in the efi manifolds... should I grind those off?


thanks all for the input and info

 

I would grind them the smoother the better

 

coolguy, thanks for the input buddy

welp was a snow/rain day today and by 10:30 am figured it was a no go on engine removal but no my mechanic bud showed up at 11

got the motor out with the hood still on with a fancy 180* turn clockwise 3/4 of the way out

couple of picture's of the start of the project.... thanks a ton all for your help and input

 

If you're planning on taking pics of the whole process and putting them on here, you're going to make a lot of happy people.

Can't wait to see how it all goes! Sweet on getting the engine out, now on to the easy stuff.

 

clean that thing up and give it a nice paint job too. i didnt look to see if this was already talked about but im sayin it anyways. good luck with the build
