Ok you guys will get sick of me soon.But is there a temp that works best for a 351w.I read that some guys run at 160to200 degrees.For best preformance what is the right temp.I run my car at 180,most of the time in traffic it gets up to 195to200 degrees.It seems to run best at night and around 175 to 180.Can you run it to cool and about what temp would that be.And whats to hot.Thanks Ron SORRY ABOUT THE DOUBLE POST.------------------

Ron,Our 351w likes 160 or less for max h.p. They also run better at night because of the cool air, unless you're jetted too lean.  SteveW

My set up now is a stock water pump from napa.180 termastat,3row rad 3years old,black magic electric fan,
How do I get my set up to run at 160 to170 degrees.Will a trans cooler help.And if so do you run the trans cooler to the rad, still.Or by its self.I use water wetter now but with a 50/50 mix.I have read that the water wetter works better with like a 20/80 mix or even a 40/60 mix.I trying to aviod buying a new rad, right now.The electric fan helped alot.Thanks for the help.Ron
P.S.I'm always looking for more power, cheap or free power is even better.I'm trying to build a fast street racer that more go then show.On a budget of around $5000to$8000.So far I'm at $2500 total included price of car.------------------

Ron,That's cool, we just let it cool between runs until you can hold onto the radiator.  We also run a 160 thermostat and a 4 row radiator and a manual tranny that isn't adding heat to the radiator. They make tranny coolers with thermostaticaly controlled fans. I'd run one of those and forget the radiator connections. The cooler the better for the tranny fluid. Get some rpm heads, a 750 holley and a 282 comp cam and your 351w will come alive. SteveW

A lot of the Water Wetters, and Purple Ice type products work best with no anti freeze mixed with them.
For bracket racing, (although I dont think that is what this thrad is about), I like to keep the watter temp at a temperature that is easily abtainable for the later rounds when you dont get any cool down time. I like to stage the car at no less than 170*, even during time runs. I have always done this, even when it was on gas. It is easier to get to 170* from 185* in less than 10 minutes than trying to get to 150* from 185* in that same time period. Makes for a more predictable car.

Kid,Very good point! We should do the same, as in the later rounds there is no time for it. But the car does run quicker when it's cooler. SteveW
