Re: LSX engine mounts

Go with the plates, then. Don't go with the ECE mounts, they will put the engine a decent bit forward in the engine bay. There are any number of places that sell the plates, including S&P. All of em are about the same damned thing.

Re: LSX engine mounts

with the plates can you use the orignal frame mounts? just bolt the plates to the motor then the mount to that? using a 4l60e will the trans fit the cross member or will it need to be modded? are th350 and 4l60e yokes the same spline? thanks in advance!!!

Re: LSX engine mounts

When I did mine I used the Advanced Adapters plates and then replaced the stock perches with the tubular type-got mine from Brothers, but i've seen them from others also. They adapt to a passenger car type mount where the Motor mount bolt runs longitudnialy (sp?)- front to back- instead of coming in from the back of the stock perch. I then used some poly mounts from Energy. I did have to drill new mounting holes about 3/4-1" back from the stock location because the pan was hitting the x-member (LS1 out of a 2000 camaro). Theres a pic of the L&R below if that helps... For the tranny I was able to use the stock x-member- just redrilled holes in the frame a little farther back and used another poly mount from Energy. I dont have any pic's but I think it was an inch or so farther back. The stock shift linkage looked like it would have worked also, but it was worn pretty bad so I replaced it w/ some Lokar linkage. Hope this helps... Good luck!

Re: LSX engine mounts

That covers most of it. To answer your spline questions read this: http://67-72chevytrucks.com/vboard/s...=700r4+splines

You can use the stock automatic tranny crossmember (NOT the 3spd one!!) and it is nearly a direct bolt up. You may need to drill new holes in the stock mount to bolt up, depending on which mount you use (or maybe for all mounts).

I suggest going aftermarket for the crossmember. If I had my choice to do it again, I would use CPP's tubular tranny crossmember, it is much easier to install than ECE's.

Digging up an old post, but I am wondering the same thing. Although I think he meant stock SBC frame engine towers. Anyone have any idea if the tubular pieces are required with the adapter plates?

Thanks!!

Re: LSX engine mounts

i ended up moding the passenger side mount to allow the stock exhaust manifold to clear. I am having to change them out to the tubular frame side mounts now since im adding a/c.......
