Here's a brief list of what you may need.
Trans mount (don't forget the bolts)
Radiator hoses (just 2 short elbows that if you ask for they may provide or at least give you the part numbers.)
Fuel pump. (My Southern Automotive motor came with a mech. pump)
Fuel filter
MSD ignition box. (not required but the car is prewired for it)
Motor (including all pullies, alternator, carb, air cleaner...)
Clutch
Clutch arm (the kit comes with the slave cylinder for the clutch)
Throwout bearing
Trans
Shifter (the ****er arm is included)
Bell housing
Motorcycle exhaust springs for sidepipe to header connection. (again, beg your dealer for this and they may throw it in.)
Header to engine bolts. (the new split lock are pretty cool and won't loosen up on you.)
