Drag and Drive Baja

[66brm]

It can be done though, I did my 66 with the car assembled, removed the old line and was able to feed it through from back to front. The hardest part was getting past the clutch tube support panel just behind the pedal assy, I pushed it all the way through to the front access panel, reached in put a bend on it upwards then pulled it back till it went through the original opening. Then cut it to length at the back.

Well, got the new fuel line run!! Took a few tries and some coat hanger and weed eater line to fish it through but it’s in. Started to lay out the pump and filter and snapped screws so stopped and worked on a bit of wiring.

Got the mini cam sync from Mario so sequential will be a go. Also got my fuel rails, and CB high flow end castings.

Just need to finish up plumbing fuel system. add sensor wires, mount the LS coils and finish pining the ECU plugs. Oh and finish fabricating and intake.

Hopping to test run next weekend. Though it will more then likely be the end of the month. But for tonight I’m riding a high of getting that fuel line in and feeling like I’m moving in the right direction.

I’ll get some photos up tomorrow or Saturday.

Good inspiration! I'm running my fuel line tomorrow so I needed the kick in the pants!

Honestly I was scared to run it. But it wasn’t bad. About an hour and a half by my self. I feel like with some help it would go quicker. Looking to have everything wired, plumbed and pressure checked by next weekend. But we will see.

Working on installing CB high flow end pieces (7362). No clue that I need to cut my tins, also need 12 point hardware that the ad says is included. Contacted CB no help.

Not sure where to find 12 point metric hardware?

Still hope to try and fire it this weekend but maybe not.

All I see is that it says it comes with gaskets. But they do have the hardware available. https://www.cbperformance.com/product-p/3334.htm

I emailed about it... got told there internet guy just cut and paste the write up without knowing.

I have an email that says as much. Just frustrated. It shall pass.

Sure I get it! I wouldn't mind some of that 12 point hardware myself.

I’m unclear why they recommended that nut, but I guess the normal 13mm ATF wouldn’t fit. I like jet nuts
for intakes they take an open box 10mm or socket.

Sideshow,

Your correct, they beef up the flange so the factory nut contacts the out side edge if the casting. Blows my mind... I’m on the hunt for options. I may just turn down hex stock and make taller nuts. I’ll check out what you posted as well.

A flanged nut like that is the proper nut to use on a header flange... if you can. With all the heat changes going on when the engine is running then the header flanges cooling off. The small area that a standard style nut covers can allow the header flange to warp and the gasket fail or leak. If the welding of the tube to flange allows the flanged nut to be installed I highly recommend using them.

I forgot to mention that it is like having a washer in place. Not always approve of the use of "split washers" in some circumstances; especially around high heat and this is one of them.

On my big beef manifolds I just took a little grinder to the intake to open up more room for a nut.

[Schweg]

Thanks Lee,

I may just pull the studs and use a bolt.

I wouldn't use bolts. The aluminum threads in the heads really aren't for install and removal.
If you take a 4 1/2 inch grinder with a cutting wheel you can carefully trim a little material on the intakes away to clear the nuts.
I also use those stepped nuts and they work great. Use a wavy washer under them and just grind a small flat into the washer once you have enough clearance for that nut above.
I had to clearance my big beef modified manifolds from Mario too. Not a lot but enough to make the nut sit flat.
That is what those fat manifolds are made for....so you can port the insides and trim the outsides to fit your build.

Wavy washers have the same problems and more that split washer have. The are also several different designs to them and, if I remember correctly, they are designed also for more light weight use; kind of like star washers are used mostly for light weight electrical work.

For intakes where there is a problem with the nut making contact with the casting relieving the area is OK as long as the notch is not a 90 degree relief but has a true radius to it. You can induce stress cracks that way.

I have had several fasteners, on the exhaust side mostly, fail and break; usually flush with the casting. Since studs stay in the heads (et al) vs. the bolts being removed and (hopefully inspected) need to be inspected for condition on a regular bases especially if the gaskets/seal is bad as the exhaust gasses can corrupt the material on both the stud and the threads in the castings.

I like studs but there are things that need to be considered when using them. In the V8 I just sold I replaced the bolts with studs on both the block and, because the SBF have vertical bolts and studs the area where the intake fits. Studs allow the heads and manifold to slide down them and not screwing up the gaskets when installing things .
