408 still overheating :/

Well I can give my experience with my overheating and not overheating problems. I have believe it's pretty much a stock radiator and put a shroud with two electric fans behind it. I usually pretty much gut my thermostat so it's more of a restrictor than an actual opening and closing thermostat. Now my first 318 had to stock water pump with the stock fan actually and that all work fine and never overheated. Then when I put the 410 stroker in I actually used in electric water pump. I also just use straight water with one bottle of Redline water wetter. Never had any overheating problems with the Stroker motor. I just pulled that out a couple months ago for funsies and put a 318 in for my wife and it has a high-volume water pump. The first thing it started doing was overheating and sucking the bottom radiator hose closed. And of course first thing I did was get a better hose for the bottom that didn't collapse. The one with the spring was kind of expensive and I didn't like the spring in there that just corrodes anyways or rust. They actually had a cheaper alternative that was just a more stronger hose as if the spring was built into the rubber. it stays a little hot a lot of times especially when it's really hot outside and one time I had it overheat on the way home from the dragstrip an extremely hot afternoon. It could just be a lack of radiator and or it could be that the water's flowing too fast and not transferring? But all in all it was definitely the electric water pump that didn't allow my stroker to overheat. It seems like that was the factor. Of course I use a higher octane fuel with the Stroker because of the compression. Both of them are set at about 35 degrees Timing. I'm the last one to tell you to buy something that's for sure because you know how us Yanks are we love to spend money. One thing I ran into with the current 318 the previous owner or maybe the owner before him was a big fan of that crap called radiator stop leak! That block was clogged so full of crap I'm not sure if I got all out of there at this point. Anyways that's my experience that probably doesn't help one bit but....
