I completed the conversion to a 5 speed late in the month of feburary. Has been a blast to due. Took longer than planed due to finding some engine rebuilder issues. Please remember to have a ford engine rebuilder do yours, not a chevy builder. I learned that the hard way.
Had the heads redone with stainless steel valves and spring height adjusted correctly. Milled .010 off the heads to lower chamber cc volume. Installed NEW SET of adjustable rockers (shaft, stands and rockers!) I found at a ford swap meet. What a find!!!! $180 !!!!
Updated the pcv system to draw from valve covers instead of the intake. installed carb spacers and changed the air cleaner element to a larger one. Installed a edelbrock performer plus cam shaft and lifter kit. You probably are asking WHY?
Well a heavy car needs lots of TORQUE and this cam has it! Most people tend to over cam there engines and make it a bear to drive. The cam I had was a holman moody custom grind equal to the 1968 gt and SCJ 6250b oem cam. This would be great for a fairlane or mustang body weight car.
the engine would not like to run under 2000 rpms against the weight of the thunderbird. The new cam Really grunts even near 1000 rpms. Runs strong up to 5000 rpms. Ideal for street fun with this 5 speed and 4.11 gears. Engine has a great sound too.
Now comes the nuts and bolts to this conversion. I started with a t45 from a 2000 mustang cobra has 31 spline output shaft! Important!!!! THe engine adapter is from bendtsens transmissions located on the web. This converts a fe series engine to a small block aod auto.
Next you will need a flywheel. Well a 390 is neutrally balanced. 428's are externally balanced. You need a flywheel from a 1993-98 ford 4.9 liter inline 6. This is neutrally balanced. The ring gear will need to be removed and the shoulder cut about .100 to match the depth of the aod flywheel. Then press it back on.
Will continue later.
