500+ rwhp + stock block = this

Correct the holes are only there to make the cast, they actually are cast plugs. The screw in thread will not pop out as easy of the coolant system gets pressurized to high so some of your race blocks have them also. I don't think they are a huge strength item but it could help a little. The alum race blocks like pictured above almost always have screw in plugs.

Makes me think, I wonder if you could gain strength from the freeze plug openings. Time to call mythbusters.

yep, fill em with lead

I'm not sure the benifit of running thread in plugs, but here in Florida a lot of people don't run antifreeze cause well it's Florida. The past few years we've had some below freezing weather. Being an ex tow truck driver I've seen a lot of blocks busted from freezing. One thing they all had in common is they still had their freezeplugs. A freeze plug hole is actually just a casting hole from when the block was manufactured. I'm pretty sure that's their only reason for being there. The most common motor you see busted from freezeing here is in boats. Most common is inboard with small blocks.

Not running antifreeze (or anticorrosion at the very least) is a dumb idea, especially if they also use tap water. I am sure I read the right combo raises the boiling point too. But "Expensive Anticorrosion Antiboil Antifreeze Wonder Stuff, but don't feed it to the dog or cat" is not so catchy of a name. Too many different metals will act like a battery and eat up the system!

Let the tech official catch you running antifreeze at the track and get banned for life. I like racing more than I mind putting a heat blanket on my motor on nasty nights. So yes, some tap water and purple ice works fine for me, and seems a smart idea seeing how I like running on the track.

Yeah i always run distilled water and a bottle of engine ice in race setups...its hard not to put antifreeze in a street car and nearly all the street cars at the track have it.

Tap water and Water Wetter here, The track guys would have killed me a few weeks ago if I was antifreeze and not water on the track...

straight water from the hose here... we put RV antifreeze in the motor during the winter if for some reason its together

 

[lizardsman]

My first time at the track an import blew a hose, after 4 hours they opened one lane. I did see an improvment with purple ice over straight water. Bout 10 degree different. But with the 4 core champion radiator heat is not an issue. Had to put a thermostat in cause I could drive almost 50 miles to worm and only be 130 or so on temp. I put a 160 in and she stays pretty much right there unless I hit a lot of traffic.

You have different track rules down south. Last time I ran around here, it is a BIG overflow tank that is required.
Some of your alluminum radiators just called. They begged for distilled water and threatened corrosion otherwise.

Concrete wall beat the corrosion to my radiator

Bradenton requires an overflow tank and will ban for life if caught running antifreeze. It's Florida, we get like 2 cold nights a year. You go to work wearing 2 pairs of pants a sweater and jacket and come home wearing shorts and a t-shirt. I had a new ac put in the house last year. Once I finish my other home project I will insulate my garage get a new door and I can open the vent he put it. Then I'll have a climate controlled garage and never have to worry again.

Two pairs of pants? What a whimp! Sounds like you're dressed up for a blizzard! It hits 45-50 deg here and the kids are in shorts and t-shirts in the spring hopping over the snow piles.

I'm adding this to the common questions thread and removing the sticky.

Yup I'm a wimp. But come to Florida when it hits below frezzingand it is 100% humidity. Your clothes freeze in minutes, iI used to ride a bike to work during winter, completely covered in ice in 20 min. Sold my bike and have no intentions on ever buying another one after that.
