I replaced a turbo 350 trans, with a M22 and my mechanic friend told me I need a longer cable for the speedo to work,,,, what should I be looking for. Any help will be appreciated..

When I went from turbo 400 to muncie m-20 in my 69,I used the same speedo cable with no problem.

Should be able to use the same cable.

Phil....how 'bout some specifics?

depends on the year of muncie, speedo slug changed from driver side(same as auto trans) to passenger side, so you will need a cable for a manual trans
car. gm still has cable available if you can find a parts man that can read parts books ;)

M-22 Speedo cable attachment is on the pass. side of the tranny. On my camino I got a cable for a Chevy van. To be correct- on the bottom of the tranny, The 3/4" left side bottom bolt has a bracket to hold the cable as it heads for the right frame rail to make a -U- turn and head back to the tranny. To get close on length.----Run your 350-400 cable under the tranny, Back off one of the 3/4" studs and wire the cable to a tranny bolt. Then use some wire to make a loop to the tranny where it screws in, or do what I did start trying different cables untill you trip over the right length. I got into this mess because I thought all cables for a 70 were thr same and pitched my org.Can you say I was a dumd A--S

Thank you all.. I will be going down under this week, so I think I have enough info on hand now that if I cant make this one fit,I will just buy the larger, longer cable that seems correct.. They offer one arround 58 and another 70 something inches.... Thanks again phil

i need a speedo cable as well, went from a powerglide to '69 m20.
i noticed year one has an 80" speedo cable with housing for 12 bucks. thats the one for the manual trans 68-72, the auto's are somthing like 71"?
just a heads up.
