The 302 ain't the least bit difficult. Just get a van oilpan and pickup and an early front cover and water pump. Aod trannys are pretty cheap because folks think they are junk. Actually the ham-handed idjits just screw up the tv cable adjustment. Intakes and carbs are cheap and readily available too.

I am getting rid of my efi stuff as soon as the guy comes to collect it. I pulled that stuff off when I put the 302 into the 64. I am a proponent of keeping it simple enough for me to repair later so I build it that way.
