Recent article in PHR had a motor plate mounting of Ford motor (I think).  Need thoughts on BBC mounting in 1st gen Camaro with after market subframe.  I'd like to lower motor 3/4" with solid mounts at stk location and fab solid mounts for lower front of engine/frame rails with poly on rear tranny mount.  Question - will dual solid mounts cause excessive stress to motor on drag strip launch and/or autox use?  Sub has solid body mounts and has welded/bolted cage work.  Thx.

If you're maxing out the strength of the block with the power you intend to make, then stock mounts (near the center of the block) can actually be a detriment, stressing the block in its main webs by not allowing it to move while the rest of the length of the block is shifting around with the torsional spin of the crank.

how high an RPM are you launching off the line at?  In the old days, lowering the BBC in the first gen Fbody was done with *gasp* 6 cylinder mounts.  But in the end, rather than re-invent the wheel, you could go to your local dragstrip and see what everyone else with an Fbody or Nova is doing. As for cornering, Indy cars actually use the block as part of the chassis, but of course the block has a whole lot of strengthening ribs to help with this.

will your front mounts be to the cylinder head, or to the water pump? is either aluminum, or cast iron?  
Just because you can't do it...doesn't mean its impossible

a thought. you can use solid stock type side mounts,then use a solid mid plate between the block and bell housing.this allows you to HANG the trans without a cross member! this will be a very rigid set up!
