Default Manual Steering Drag Link hits Oil Pan 70 GTO

I dropped a different engine in and the drag link is hitting the oil pan. I tried lowering the rear of the trans to tilt the engine, but that will not give enough clearance and puts the engine/trans at too much of an angle.

I have a borgeson manual box. i believe the rest is stock. the only number I can make out on the pitman arm is 5679.

See anything wrong here? wrong pitman/idler? The drag link seems high to me compared to the frame.

any other tricks?

thanks, Steve

Although my '66 GTO is of course a different year than your '70, my car has the original power steering pitman arm, and it is stamped with 5679208. Since your pitman arm also has "5679" stamped into it, I'm wondering if it's intended for a power steering application and there is an incompatibility issue with your manual steering drag link that is causing the problem. Is your pitman arm the same one that was in the car before the engine swap? Same oil pan as the previous engine? Same engine mounts?

Thanks, the manual is 5697206 but the last #s are gone. I'm trying the motor mount shims and ordering a manual pitman just in case.

Closing this out. Was not the pitman arm. Cradle sag.
Solution: 3/16" spacers under motor mounts from Butler. Worked perfectly. only slight driveline angle adjustment needed after. Now have 1/4-5/16" clearance.

Manual vs power pitman arms are not interchangeable, as the diameter is both different & can not be swapped.

Good point, Chris.

One thing I'm curious about is why the shims/spacers were needed when everything (presumably) fit fine with the previous engine and there were no other parts changed. Or maybe it was touching before with the previous engine but OP only happened to notice it after installing the new engine?

Chris, correct. thanks.
Other engine cleared with an iron 400 block and 7qt moroso oil pan. this one is an MR1A block with an 8 qt moroso deep sump pan. maybe that combo sits differently. same butler poly mounts on both.
