New Shafts

[1976Blazer76]

I'm doing a frame off and my blazer and everything is new. So, I'm at the point I'm gonna be getting my motor or my driveshafts. Was wondering if you guys think I should drop my motor in first, so I can measure up the correct shaft length, or will the motor weight not really matter when measuring my shaft?

the 350 in my truck drops the front of the truck 2" or so. thats with the 4" rancho front springs. not to mention it'll be hard to get the tranny to the angle it would be when bolted to a motor to get accurate measurments for the shafts.

i vote wait till you get the motor in.
