'69 Muncie - new harnesses throughout -

Is the feed off the neutral safety switch continuous, once past the two-prong connection, all the way to the solenoid? When the solenoid would no longer engage, I thought the relatively new neutral safety switch had gone bad. I bypassed the neutral switch by bridging the ignition switch feed to the existing solenoid feed...alas, still no activation at the solenoid.

I then installed a jumper wire from the solenoid to the outlet side of the neutral switch and, voila, the solenoid powered up off the ignition switch and I was able to start the car.

In my wiring diagram I see no junction on the purple feed to the solenoid other than the one directly above the pedal assembly. Is there one further downstream I should look for. I'm trying to avoid tearing into the harness.

Do you stagger jet your 4053?
Do you use the bigger accelerator pump?
What size nozzles do you run?

paul

Can you share the PN and specs of the Hooker headers?

Thanks

I still have another new repop of the correct Muncie bellcrank (which was sent by a supplier as the correct bellcrank for the Saginaw)....our Z car has original assembly installed...this car is a good friend's 52-years-owning 307, saginaw 4 spd convertible...he'd had headers on the car in years past but now needs the reverse lockout and backup lights operational....sometimes you gotta make do with what you have...

Appreciate your advice and guidance!

The saga of the Saginaw 4-speed reverse lockout idler assembly (bellcrank) mounted to frame: see the illustration above...

Resolved the problem of the Muncie vs Saginaw configuration (each the reverse of the other in position of the rod ends) by cutting the Muncie assembly arms at their base (or top), flipping them over and welding into position. Works like a charm on the Saginaw and with good beads and grinding the revised assembly appears untouched.

Thank you...I'll now fabricate rod. I think (have to go to my AM to be sure) the bell crank and upper rod carry the same part #.

Again, thank you.

paul

I can tell you for a fact that the bellcrank for that Saginaw is different than a Muncie. I do believe the Saginaw and TH350 & PG share the same one.

You are totally correct: the M35 "idler lever" is the direct opposite of the bellcrank for a Muncie installation. Now I have to find one of those PN3895290.

paul

Now there is one on E-Bay....

Thanks for the heads-up

paul

Thank you...none of the parts suppliers is carrying this rod...a good friend who has owned his '69 convertible since 1970: base SBC, saginaw 4spd, removed the lockout linkage to install headers many years ago. The car is now restored but the linkage is long gone...he had in his new parts bin the reproduction Muncie linkage.

I'll now fabricate rod. I think (have to go to my AM to be sure) the bell crank and upper rod carry the same part #.

Again, thank you.

paul

That would be greatly appreciated and helpful.

paul

Can anyone give me dimensions and a picture or good illustration of the lower rod....Saginaw 4 speed

thanks

paul

Have you considered plugging the secondaries' power valve opening, gone down 1 step in the the vacuum spring and increased the secondary jetting to 84-86?

Does anyone have either a source for the Saginaw lock out rod (shifter to bellcrank) or its dimensions so I can make one to spec.

Small-blocks use lower lock rod 3955773 on the Saginaw, not the same as Muncie, seemingly much shorter rod due to the difference in placement of reverse in the cases.

Thanks

Paul

Rotated crank 1/4, spun the toothless distributor, repeated for entire cycle and got oil at rear cylinders.....which is a success, I think.
