Re: engine years. options

If your taking a steel tank and adding the sump (low point) then MIG is fine, TIG for alum or stainless tanks. I wouldn't really use silver solder (Braze) on larger structural apps if it can be avoided. It is great for things like bracets, weird fittings etc.

I haven't really used silver soldier in too many automotive applications. I've used sil-floss on things like radiators/heatexchangers, or like brasing for fittings. I guess I'd be more likely to use it on something like a cracked door handle or something where I needed the fill more than the strength. There may be old school guys with way more braze-welding type experience that could be way more specific.

Re: engine years. options

Looks kinda like an injector O-ring but I can't tell from that distance. Did you pull the injectors out before the manifold, or leave it all together?

If you pulled it apart, the oring could roll off the injector tip and fall there when you pulled the manifold off. Makes sense in my head at least.

Re: engine years. options

Looks a little big for an injector o ring. My guess is its an old fuel pressure regulator o ring. They go bad and are replaced fairly often. Its also in the right spot to have fallen down under the intake.

Re: engine years. options

i took it off together. .. i now have engine sitting in place.... thinking it will only go back one more time so... i should, (while the weight is on suspension) swap in my 2.5" spindles and disks. run new brake lines. prep and epoxy prime firewall...
another question... are 2.5" spindles and 2" too low for truck pan? thinking i should find good stock springs and sell drops... i DO NOT want to notch frame and i have 4" springs for rear

In general I don't like the fit of the truck pan in relation to the xmember, let alone the 4" it hangs below. I'm about 5" drop up front, and the truck pan would scare me at that height.
I'm running the LH8 pan and the clearance is now comfortable. It ends up right about at skidplate height, and I've bottomed the xmember out on the Indiana-Kentucky bridge on I65 @75mph with no damage to the pan or anything (cept my underwear).

Re: engine years. options

Doing disks is easier when you do the spindles at the same time, you can just go 5bolt and be done with it.

Re: engine years. options

i have most all the parts, in a box on the shelf, 6 bolt disks, calipers hoses pads, spindles.... no tie rod ends or ball joints or bearings.
i think however 2.5 spindles plus 2" springs is too low.
