And do I have to wait the 3 hrs for it to cure with the the super high tack or can I start the motor befor that?

Frankly, when applied correctly the RTV creates a better seal.  High Tack is best suited for paper gaskets when you're attempting to retain a stubborn gasket in place during assembly.  But, it will work for non-paper gaskets, too.

...Try this before you invest in the High Tack sealer:  Apply a thin smear of RTV to both sides of clean gaskets and install the covers only finger tight - just tight enough to retain the gaskets in position and force a tiny amount of sealer out along the edges of the gaskets without actually compressing the gaskets.  The idea is to get the gaskets to seat into and even out the film of sealer without actually clamping the gasket and forcing it to shift.  Let the silicone set up for 2-3 hours then tighten the cover bolts to the finished torque.  Carefully inspect for leaks.

If the above method doesn't provide a satisfactory seal, use High Tack on both sides of the gaskets and call it done.  High Tack can be put into service within about one hour after assembly.

Hope fully I can try this tomorrow thanks for the info!

Finally got to test drive the truck after the fix

And this happens

I was accelerating fairly easy and all of the sudden the truck hits 40 ish mph and try's to die

This happens all the time around this speed have any ideas what it is? My thoughts are ignition.

My timing is set to 7 which is were I had it before it broke (factory is 6 but adjusted +1 for elevation)

It also has another fuel line on it (few more bends to make it look nicer) that wasn't on it before it broke

Changed my fuel line back and got a new cap and rotor and it's still doing it

But it only does it under load and if i accelerate slowly it will die around 25-30mph if i accelerate hard it will die around 40mph

Could the distributor be off a tooth

And could the coil be bad?

Or is the motor vapor locking at high rpms

Unplug the distributor vacuum advance, go for a test drive, then post what happens.

[Chisholmcody]

Just did that and it's still doing it at around the same speeds

Plug the vacuum advance back in and unplug the EGR valve then go for a test run and post the outcome.

[Chisholmcody]

Plugged it off but noticed it was pulling no vaccume to the egr (unless it's on a timed vacumme) but it was still not going over 40 and dying

Heads up guys if you install a fuel filter backwards it will cause this issue lol

I hope you replaced it rather than just turned it around or sediment could wash into the carburetor.

Last time I checked, filters had the word "FLOW" with an arrow pointing in the direction of flow or the words "IN" and "OUT" on each end hahaha.
