Need new rear end
Have 67 short step with 12-bolt 3.73 (I think).
-- Raised one wheel, put in neutral, etc.. -- When rotated tire two turns, drive shaft turned approximately 3.7 turns. Should have been stock in truck (had a 250 6 cyl from factory). Looking for a better ratio for daily driving / highway. From what I have read 3.42 or 3.08 should work. Question 1: recommendations? Question 2: Anyone have one? Thanks. |

I have a 3.07 in the GMC, and while it makes it an awsome freeway flyer, I truly hate it off the line. (and my engine isn't exactly stock either)
What stage are you at with your ride? Is it on the road, or being taken apart...What? i have found with my Small Block, that it is dead under 2800 RPM, and really kicks in at 3000RPM...kinda like a turbo almost. I found that it actually gets better MPG spinning the higher RPMs. At one time I was looking to trade a 3.73 for my 3.07, but you are a bit far for that. |

On the road

Have 350C tranny. |

Check the parts board Bobvilla has a thread under the post:
Parts for sale in Dallas TX. Looks like he has both 5 and 6 lugs. Not sure of the ratios Also you might want to search for one of BBS1965 posts, He is in Waxahachie and last I heard he was covered up in rear ends. You could send him a private message or e-mail. If all else fails I saw one in a salvage yard over the weekend, it was already pulled from the truck Can't you just switch out the gears and keep you case and axles?

Change Gears
Yep - Willing to change gears in one piece - if possible.
Don't think I am up to meshing the gears seperately. |

Yeah, sometimes 3.07's are nice.
This is without the lock up converter like your TH350C has, knock off 100-200 RPM with your set up...asuming you have 28 inch tall tires like I do anyways. |
