Issues with lsx swap combo.

Hey guys, I am having my issues with some of the parts chosen for my lsx swap. First off the car is a 69 camaro. The motor is an ls1 t56 combo. Here are the parts I have chosen are psi harness, LUK gold series clutch, Dynatech headers, dirty dingo mounting plates, energy suspension urethane motor mounts, and the holly lsx swap oil pan. The mechanic helping me with the install has told me that due to the oil pan I have the motor mounts and headers, I talked to my buddy and he told me that all I need to do is get the taller engine frame mounts and this will eleviate the issue at hand. That almost sounds to good to be true I even called summit to see if this was factual and they said there were some difference in the 327 engine frame mount vs the 350 mounts and they confirmed that there were two different frame mounts. I also found this link http://www.pozziracing.com/camaro_engine.htm that suggests the same thing. My buddy said he used all these parts I have except with a 4l60e and I guess the question is are the frame mounts different in height, 327 350? Should this make a difference at all? I ordered the mounts already from summit but I guess I am trying to ease my mind is all really. Thanks in advance guys, if I left out something I apologize, I am a lil frantic and hoping this is just my mechanics unfamiliarity with the some of the parts I chose.

Re: Issues with lsx swap combo.

Yes there's a height difference in the frame stands, but not much. Probably not enough to help the pan clear the frame.
I used the Dingo plates, Energy Suspension engine mounts and Holley pan, and I still needed to shim the frame stands up for the pan to clear. Keep in mind that if you need to raise the frame stands to create this clearance, you may have a tough time getting the engine mounts to line up with the holes in the stands. You may have to open up the 3 mounting holes in the base of the frame stands to move them up or down the frame to help everything line up.

I got the taller stands and its still not enough, honestly guys its looking like I may have to sell the holly oil pan and go with the autokraft pan. I guess the holley is for sale now.

Hold on.... I had that same issue with the Holley pan and Carshop motor mount adapters.
I made a pair of 1/2" thick spacers to go between the adapters and motor mounts. Now the pan clears by about 1/8" or so (poly mounts, little-no movement). Could also use washers to see what thickness you need to make the spacer.
Its worth a look Just use the old SBC motormount as a template. A WHOLE lot cheaper too.

Holley pan IS the Autokraft pan....Holley bought the design.

Re: Issues with lsx swap combo.

I had the same problem. Holley LsX pan, Dirty Dingo sliders and Energy Suspension motor mounts.

I just used the ES pre-load plates (which they say aren't needed) as my spacer and got the clearance I needed for the oil pan. I have part numbers somewhere in my thread for which frame mounts I have, as well as the ES motor mount part numbers. I can dig them up if you need them.

I used the pre-load plates and still needed to shim to make the pan clear.
Every car is different. Gotta remember that these 40+ year old cars aren't made of granite so they're all going to be in some different state of alignment and wear. What works for one will not always work for another.

True enough, but there are also 3 or 4 different engine frame mounts that can put you at different heights.
