Quote: I am not trying to contradict Tom Quad as he is always helpful, but Mr Six Pack, Bob Karakashian uses a 160 degree thermostat in his pure stock 6 pack Super Bee, and does not think the 195 is required...
He also recommends 38 -40 degrees total timing and no vacuum advance for performance use. Granted he does run real race gas and has 11 to 1 compression which is allowed in pure stock.
Good luck with it!

Myself and others have run 40-42° on factory heads. Why? Because the et time slip says so. Same with the 160° thermostat.
These and many other details are not that important for your stuff to run good, but it makes a difference if you want it to run quicker/faster.
To the OP. Much what is posted on this forum is often times based on opinion verses real data or fact, or what someone has read somehere else. Your challange is to assign the right level of reality of these opinions as they apply to your application. This is especially important on the six pac, as cherry picking others suggestions can cause you more problems than benefits.
