vortec head coolant sensor '71 Chevelle
I'm trying to get my motor filled with fluid and started. I can hardly wait! But . . . I'm hung up on my coolant temp. sending unit right now. I replaced the 307 in my '71 Chevelle with a 1997 vortec roller block. Problem is, the coolant temperature sending unit from the '71 is too big for the hole in the vortec heads! What do I do from here?
