LS3 Clearance Issues to Frame

[Toddoky]

Here's some images that will give you some comparative perspective. The first three images depict an LS engine in the frame of a 68' A-body mounted with the Hooker forward-bias engine brackets and transmission crossmember...notice the tight clearance between the front corners of the sump of the Holley 302-2 pan and the back side of the engine crossmember and the clearance between the inner tie rod ends and the 302-2 pan. The next two images depict the Hooker engine brackets attached to the frame and the last two images depict an LS mocked-up in a Chevelle using the Hooker rear-bias engine brackets. You can see the use of the 4th-gen F-body engine mounts in these last images.
