What trans cross member do you intend to run? I ask because there isn't much difference in the mounts when you compare brands. However, I recommend that you'll want to use a cross member made by the same brand to help with final engine placement. They are typically designed as a set and mix matching could cause you issues. Holley for instance, sets the engine 1/2" off from the others and thus their cross member is recommended. Additionally, some of the cross members are better suited for certain exhaust set-ups.

I was planning on using the stock cross member and stock K member and maybe some lsx innovation slider mounts but know what oil pan to use. I was also hoping to use 1 7/8 long tube headers. Really needed to know which was easier without breaking the bank

I used cheap 1” set back adapter plates. Worked fine.

Youll have to modify the trans crossmember. The mount doesn’t land in the same spot

Re: Motor mounts used with your 5.3l

[color=left=#000000] I originally planned on the Hawks with the Jegster torque arm. but clearances did not work out. First of all the Hawks cross member is the most ill fitting part I have ever seen, the grinding and drilling I had to do to make it fit was crazy. The Jegster T/A was not going to work with the LPE 4" driveshaft I have with about 0.100" clearance with the torque arm attach fitting bolt. So I decided to bite the bullet and buy the Holley cross member and ya know it was a pleasure to fit it in the car it fit perfectly with no mods and with the Spohn engine stands and notched factory K member. Exhaust clearances look like they are going to be as good as with the Hawks cross member even though the Holley is much beefier. I will have to buy another torque arm that works with the Holley cross member and I can use the driveshaft I have.[/color][color=left=#000000] [/color]

Re: Motor mounts used with your 5.3l

I'm using the UMI adjustable mounts. I haven't quite got my transmission crossmember figured out yet, but I will be modifying the factory piece.
I'll be posting some pictures of the engine in the car soon.
