I 'm building a 351w to put in my 84lx 3.8AT. I'll be using the t-5 from my 95GT and a 351w motor from a 89 bronco. I'm also putting a holley 700dp on it and run the same fuel pumps the 3.8 had by using a mallory 4309 regulator. I'll use my msd 6btm and a hei dist. to run the ignition and I imagine the speedometer will still work fine since I'm leaving the wiring intact. I also swapped the 95's axle and spindles onto it. I've found a way to modify the alt. bracket to use the 3.8's alt. and I got a billet 28oz flywheel so I could use the t-5. I'll also use the 95's brake pedal since the clutch pedal is attached to it. My main concern at the time is if the fan shroud from the 3.8 and my bbk long tubes from my 95GT will work. If anyone has any ideas I would very appreciate the input. Thanks
