Author Topic:   detination and temperature question
posted August 10, 2004 12:44 PM
we have only been hitting about 170 after the features. 355 flat top on gas 100 octane or so. Vortec heads. Timed at 32 degrees. Good cooling system.We are running a Rochester 2G carb. Had run 73 jets in it thus far. And dropped down to 70's last week. Will the temp jump way up before we need to worry about this thing detinating? And how for down with the jets do we dare to go?

On the temp problem if its a good motor go up to 34-36. That might raise it some. Then run a lil caedbiard or something. Restrictor maybe get a tstat or go smaller hole? Something that if it dont work you can change back quick.
Jets read your plugs. Adjust accordingly. You want them a tanish color. Black go lower whitish go higher.
