'70 corvettes do have a removable crossmember, independent of transmission type.
'68 and '69 corvettes have a welded crossmember for manual transmissions and removable crossmember for automatic transmissions.
An M22 'rockcrusher' transmission is far noisier than an M20 due to the straight cut gears.
No. The subframes are not the same. The 68-74 had the steering behind the crossmember and 75 and up had it in front of the crossmember.

The Corvette wasn't made with a 327ci V8 in 1970. A 1970 Corvette with the 350ci ZQ4 V8 puts out 300hp and with the 350ci LT1 V8 puts out 370hp (these are gross horse power figures).
A 1970 Corvette Stingray with the 350ci LT1 V8 can go from 0-60 MPH in 5.7 sec. and has a top speed of 122 MPH.
The corvette factory can get all of that
