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. |
Re: Motor mounts used with your 5.3l 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 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. |
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. |
Re: Motor mounts used with your 5.3l Ive always had good luck with stock sbc motor mounts and setback plates |
Re: Motor mounts used with your 5.3l I still looking for a ls1 oil pan but I did buy some solid mounts on the block side and waiting to order Umi frame mounts. I'll post pictures as soon as I get everything |
