IMHO you are setting yourself up for a costly timeconsuming mishmash of problems. First the only "real" 6 cyl 4 speed is the dagenham which is expensive , hard to service (English) and reqires many unique parts like bell housing, shifter rods, etc. If you do not have one, don't buy one.
Next you can use a v8 top loader, but why? The final ratio is the same ( 1 to 1) so the only advantage is hole shot acceleration, which, by definition, with a stock 6 cyl you don't have so a 4 speed does not buy you anything plus there are still a lot of issues and parts to change out, many of which get purchased and then thrown away when you then put in a
289 or 302 engine. With that engine you are going to replace your rear end, driveshaft, front hubs, steering, wiring, and wheels plus many more parts . If you really want to purchase stuff to replace good parts on your car, maybe it would be better to replace the car now with one that has what you really want
That being said, if you still want to do this, save yourself a lot of time and money and buy an early 90's MATCHED 5.0 liter engine and 5 speed from a running car, either retain the fuel injection or convert to carb, and not fight all the pulley , flywheel imbalance, and many other problems. You will still have to convert to the 5 lug steering and brakes for safety reasons but a least you will not pay big $$$ for a lot of problems. N
problems others have faced: bought a 5 bolt 4 speed toploader and it will not fit. Bought an SROD and later found out the issues. Bought a Torino 4 speed and it does not fit. Bought a mustang top loader for $800 and it needs $1200 in parts. The correct bell housing does not fit the correct flywheel and the correct starter doesn't fit either one.
If you REALLY do not know your way around this thing, you will be mad for years to come.
