Weighing my options

I already have a 650 double pumper and headers alot of small block parts. My cousin just is a big block guy he loves them he has a 400, 440, & 383 and he said he would part with the 383 if i was interested. But if i stay small block i could get a 4-speed.:thumblef: And there are alot of aftermarket parts for 360's now which is nice.
