Hey guys. You have all been very helpful to my new hobby as a racer and I appreciate it. I have encountered a new problem now. I had some work done on my heads to help the flow and at the same time realized my carb was shot. The machinist "lent" me a holley 500 carb that he used when he was racing and it has had some stuff done to juice it up too. But every since I put my better flowing head and his carb on my car I have been running hot. I had the distributor timing way advanced at first and it got up to about 275 after the first race I turned it back a little but it is still getting up to about 240 - 250 degrees. I asked the guy that I got the carb from and he said there is nothing in his carb that should cause me to run hot and I need to make a shroud for the fan. What do you guys do to help keep your engine cool during the races? Or if you have any suggestions on what may be making me run so hot, let me know. I think one of the problems is my overbore 0.060 that is a little too big for my tastes but heck, cant get everything you want when you buy a race ready car.

First of all, was your header glowing red when you came in, if it was this indicates leaning out, over heating is never a problem we have had on my car due to some modifications, we took the thermostat out, puat a radiator out of a V-8 mustang in, put an electric fan on, and put a good water pump on, in a 15 lap main, with never lifting off the gas, my car never goes over 160 degrees and i never have to turn the fan on. so i dunno maybe this will help you

hey i run mini-stock and i got a idea that might help u out i used to do it to keep my car kool. ok if u can find and thick padding that can retain water try packing that along the sides of ur radiator. before u race soak them down with water all over. make sure it is wet down really well then check it again just b4 u go out to race. i hope this can help u get up front.

put in new plugs then run hot laps.
then you should check your plugs!
if they are white then it is lean.
if they are golden brown then it is ok ,if they are little black too mutch gas .
If you know what size jets you have get the next two or three larger sizes and the next size down. they are cheep and could save your motor. if the stock 2bl worked then go back if this dont help the over heating prob. good luck

DUHHHHHHHHHHHHHHH
sometimes I really do some dumb stuff. But hey we all do sometimes. I don't keep my car at my home so I am not able to just go work on it. I have to make arrangements to get to it, so usually I just grab it and head to the races. Seems like the past month I havent done anything to the engine as it is working fine except for getting hot. But other than that it is running well. Anyways, last Friday I decided "hey you know what. I havent checked my water level lately, ****." so I pulled off my cap and I was about a gallon low. Dang sometimes the small stuff gets overlooked, but I wont ever forget to check that before a night of racing again. I added a gallon of water and it never got over 180 the whole night. LESSON LEARNED!

The engine is running stronger after the headwork. I am very happy with it. I still get smoked at the track though. But my car is within the rules and I run in the middle of the pack consistantly pretty much, that makes me feel good about what I am doing. I am going to go to a track in Arizona to race in November, heard they have a big showing in the ministock class, gonna see how I run with a big pack of cars where the track is more consistant with the rule enforcement. I will let you all know how I did there before thanksgiving.
