text: where can i get parts and how to's for a v-8 conversion in an 86 nissan 300zx!!!???!!??!!?   tough conversion. do-able, but will require custom headers, motor mounts, firewall mods, mods to the trans tunnel, custom driveshaft and of course, a new rear.  probably the easiest way to physically get the engine into the car would be to use engine plates.  they will give you the most room to work with when it comes to putting an exhaust on the thing. oil pan issues may arise as a result of the stock crossmember, just be aware of it.  one or the other (crossmember or pan) may require surgery.  working your way back, the struts up front need attention--the added weight of the small block may cause front tire clearance issues.    hammers, mallets, torches--they can be used to "modify" your firewall and trans tunnel as necessary.  your trans crossmember will require attention to adapt the new trans.  if you do the measurements correctly, just about any driveshaft shop can handle that part of the project.  the could probably help you with getting that rear narrowed.  i reccomend a ford 8.8 (readily available) + you can get decent axles, brakes, and wheels to go with it at a reasonable price.
