Help.. need thermostat info. I am finishing up installing a ls1 in a 69 camaro, and am currently installing guages. I have to drill and tap the t-stat housing for the sending unit. And thought while this is off, maybe I should change to thermosat. I know some say this is benificial? Is it, and what kind, and how much, what degree? I am running in AZ. I am going to have ls1 edit. So is it worth it, or should I just leave the stock one. Thanks.

Re: Help.. need thermostat info. In desert heat like that, you will benefit greatly from a 160F thermostat. Typically, LS1's seem to run about 200-220F under average to heavy load. Swapping out the thermostat for one that opens at 160 (and completely opens at 178 I believe), allows for your coolant temps to drop drastically. Combined with ls1-edit and changing your fan operating temps to 180, you will see about a 20-30 degree coolant temperature change. And as we all know, heat is a huge enemy of horsepower, and one of the top contributors to deterioration.

Re: Help.. need thermostat info. Is there no way to put the sending unit in the head or something? Seems like it would fluctuate alot at the t-stat. Anyway here's where I got mine. http://www.jegs.com/cgi-bin/ncommerc...12&prmenbr=361

Re: Help.. need thermostat info. For my LS1 powered sandrail, I removed the plug at the back of the passenger side head and tapped it to 1/4" pipe thread and stepped it down to the 1/8" thread of the Autometer sending unit.
Be careful not to thread it too deep or the bushing will bottom out on the threads before it seals. I also used several layers of teflon tape.
Does anybody know if this placement will give a false reading or not?
