ive been running the one in my Monte for 11 years now with a 4000 stall running 7.70 in the 1/8th and for the last year with a 100 shot of nitrous and its still together and its basically all stock inside . I like the tranny , its light and I like the gearing. Its time for a rebuild and if it held up at the dragstrip for this long im sure if I upgrade to some better parts Ill still get use out of it for a long time. Thanks for the recomendation on the sprag.
