robert...i like the 4g54b ... i have one in my forkllift that is showed.... i kinda have a " mancrush" (as my wife calls it) on datsuns .... i really absolutely plan on owning one in the near future... and last night my friend and i were discussing a 510 wagon with a 620 nose... hideous was my first answer but kinda growing on it.... and i dont think there will be enough weight in the ass for hualing anything other than the drift trike and groceries. ... hopefully i will be able to give my friends mustang a run for its money when its all together. just got mounts for the engine so i am moving forward
