How to verify engine alignment?

[jrblanke]

Hey guys, I am working on mounting my engine to the frame this weekend. I am following Glock's build, and am using the #2 style plates and have modified the passenger side plate to accommodate for the AC compressor. This moves the motor mount back 1.75" from the stock location.

Instead of moving the motor mount back on the engine stand, I am going to move the engine stand back on the frame and weld some metal onto the frame.

My question is this: Since I know that the modification to the engine adaptor plate moved the motor mount/engine stand back 1.75 inches, can I just measure and drill new holes on the top of the frame, bolt down the stand, and know that the engine will be aligned properly? How do I verify the engine alignment? I don't want to be all cockeyed in there.

Are you referring to cockeyed from side to side? Easy enough to check with a small level on a flat engine surface as long as your frame is all level

I mean instead of the front of the motor being exactly perpendicular to the frame rails, the engine is turned to one side. Like if I get the motor mount too far back on one side.

Gotcha...I'd just find a center point like the front crankshaft bolt or pulley and measure to each frame rail..then measure your tailshaft the same way or if you don't have the trans in measure to center of flex plate frame to frame..that should get you real close as long as your getting equal measurements side to side..
