1968 M20 with BV
« on: November 30, 2023, 12:15:54 AM »
Could you have a 1968 Z/28 with an M20 and a 4:10 BV rear axle ratio?...
My friend said there is no such thing. Because you would end up with a granny low. And that 4:10 would have to have the M21 from the factory?  Danny

My 69 Z has an M20 and 4:10 rear.   1st gear isn't a granny gear by any means.

I changed the non original m21 to a m20 in my 1969 Z with 4:10,s to make easier to pull off from dead stand stills. Did in my 64 vette with 4:11,s also.
