Something I just remembered. Before or during the swap you will want to replace the transmission mount for a polyurethane one from Energy Suspension. Also, replace the transmission crossmember bushings with Energy Suspension pieces. Put subframe connectors on that car before adding any power to it if you haven't already or else your straight frame will be gone in no time. Motor mounts. Do NOT re-use the old ones if they are the factory stock rubber ones. Use the new Energy Suspension motor mounts, Moroso solid mounts, or convertible motor mounts. People will tell you not to use solids on the street because they vibrate. Yes, they will vibrate if you have a problem somewhere in the powertrain. If no problems are present then vibration is minimal. I have Moroso solids on mine since 1997 and it's daily driven. Another benefit from any of these is the elimination of flex from the powertrain which can cause the unibody to buckle. Another reason for subframe connectors and/or cage. Get the rear torque boxes welded up. If you do this before the V8 swap then you'll save yourself a lot of unneeded work later on.
