Hi, Thanks, excellent sites. Weavermill didn't mess around cutting corners.
In a sudden passion for the hobby I may take the plunge, but I am probably too cheap and lazy right now. I will wait and see if something breaks and forces my hand, otherwise, color me yellow thx "waynec" > wrote in message news:RjjEe.334$eg4.226@trndny01... > 700R4: > http://www.bowtieoverdrives.com/index.shtml > > Richmond 5-speed: > http://www.weavermill.com/trans/richmond.htm > http://www.corvettefaq.com/c3/Richmond_install.pdf > > Tremec: > http://temp.corvetteforum.net/c3/gwhite75/ > > Elwood wrote: > > Hi, am wondering about the feasibility of swapping the Muncie out for one of > > the side loaders from an early eighties Chevy truck.

The ratios are :3.090 1.670 1.000 0.730
That first gear is a stump puller. You're going to surprise a BUNCH of people at a few stop light grand prix because you'd have to have a 4.98 rear end with the stock transmission to get the same effective ratio, assuming the Muncie has the 2.20 first gear. It will make 180 hp perform like you have never seen. The step from 1st to 2nd is SO wide you probably won't be happy with performance after you shift though, because it is going to take the engine out of the optimum torque band. The Muncie ratios are closer and keep the engine in a narrower torque/rpm band with shifts. You may want to look at an alternative - swap out the rear end. It may not give you the engine speed reduction you're looking for (e.g. - if you have a 5.55 rear end now, you need to drop to a 2.59 and I'm not sure there ever was one that low - maybe someone else can say for sure). The transmission swap will work. At the most you're going to have to adapt the mounting bolts for the tranny to the support (I think the bellhousing is the same pattern), tinker with the shifter and linkage, and maybe buy a new custom drive shaft which is no big woof. Please post your results here if you move forward with the tranny swap. It would be interesting.
