MUNCIE-4 SPD HURST SHIFTER UPGRADE FOR DRAG RACING?
I HAVE A 69 FIREBIRD 455 WITH A MIUNCIE 4 SPEED,I WANT TO RACE MY CAR FOR FUN ONCE IN A WHILE AT THE 1/8 TRACK, HAS ANY OF YOU GUYS MODIFY OR UPGRADE THE RODS TO MAKE THEM SHIFT BETTER WITHOUT FLEXING THEM...I PLAN TO KEEP THE STOCK ORIGINAL SHIFTER, HOW ABOUT CHANGING TO STEEL BUHINGS....ANY IMPUT WILL BE GREATLY APPRECIATED---JOE

The shift rods from a 70 are much thicker and less flexible the prior years.

Steel bushings hold up better than the nylon ones and I always lube mine with white lithium grease on both ends.

How do you expect to keep the Muncie together after the 2-to-3 Upshift?
Are you running an OHC-6? |

I don't know what power level you're running but with spray I put about 525 to the back tires. I upgraded my munchie by adding the Autogear case and iron midplate and M22W gears (after I shattered the factory case and 1st gear). Then I welded some small angle iron to the shifter rods becuase they were flexing and I'd get stuck in 2nd gear which sucked.

Dude, dump the all caps.
No one like being yelled at the whole time. It makes for a bad read. |

If you can't get it to go into 2nd gear at RPM then maybe your clutch adjustment is wrong or your syncro's arn't grabbing properly. Are you running synthetic or regular gear oil?
