well my only concern was it fitting into the block, not leaking at point of entry and reading at least, if it read wrong I can change that. I could care less how far up out of the block it sticks or what way it's bent. I got my factory one in it and it works fine, just was looking at the cheap chrome ones. The one in dad's truck only has a slight bend in it and only comes to the bttom of the valve cover basically. it may be a bit harder to get to, but I dont mind.
I was just thinking they would not fit the hole or seal. I was also told the stick was too short to reach down in there, but I don't know. Summit has some for 80-82's and some for motors up to 86. I don't feel like buying one to take a chance though.
