Lowering the engine....what parts?!
 

Gents, need yout help trying to figure out a solution to this one.

I am preparing for an LS swap and am concerned out the engine's mounting height. Not because of the LS itself, but really to correct my current SBC height.

Quick version....i want to lower the height of the engine. I have a 71 with the 'old' here bolt mount on the engine side and the single bolt through the perch. This is not the clam shell style.

I have find if figured out that if i swap to the 73+ clam shell perch and mounts, then use the 'car' LS mounts that should lower it.

Is this true? If so, about how much can i expect?

Finally, if this will work....where do i find these perch?! I cant seem to find any aftermarket.

Or is there a better way to do this?!

Thanks!

Ive looked thru the search on this and all I can find is the 73 and up give clearance but nobody says how much.

On my c10 I used ECE (early classic enterprises) motor mounts and perch’s. On my k10 I used the 73+ perch from a wrecking yard.
The c10 bolts right in no issue the k10 had to be modified quite a bite to work.
