[Tigers] Overbore run hot?

[awtiger at cox.net]

Allan:

My experience with my Tiger tells me that, if the cooling system is not in tip-top condition, there is a likelihood that it will run somewhat warmer than it should if the motor has been bored out that much.  My car also has a .030-over 289 in it as well.  There is, of course, much more that can have an effect on operating temperature, such as the presence of performance-enhancing bits, but just remember that the cooling system was designed for a standard-bore engine, and even then it was considered to be on the marginal side.  

When I go through the mechanicals of my car, I plan to stay as close to stock specs as possible; but, then again, that's the way, uh-huh uh-huh, I like it!!
