Re: [Chevelle-List] Alumninuminumeum radiators vs copper vs ?

Kelly,    yes, with blockages in the system,that act as a "restriction" you will get away with this.... problem arises when cooling system is is flowing at optimun,you will not see"too cold",what you will see is a motor that does not warm up fast enough(more wear) and a motor, that, under speed[freeway]or heavy load,will accually run hotter.With the thermostat installed, you will see higher inital temp,but lower max temp and less flucuation........[which results in more consitant power] through testing it has been proven that sb chevy's perform better if kept in a operating range of 145-190 degrees. Newer[comp controled]sbc's are maintained  at a higher temp for emission purposes and newer cars experence a great deal more wear than the engine blocks found in older cars, that is one of the reasons why you'll find more older['70's] "010" 350 blocks w/standard bores than any newer casting........ [also these blocks contain more tin & nickel than the newer blocks/they no longer concern themselves[the manufactuers] with a block that will go 150k with 1thousandths wear,due to the fact that newer cars simply dont last as long in general]   p.s.     i'm sure i'm opening a hornet's nest here, but bring it on....   This is what i do for a living but i know there's always more ta learn!!!!                            Rob Means "be good,if not,be good at it     [EMAIL PROTECTED] ----- Original Message ----- From: Kelly C.

VERY true!!!! most commonly experenced when thermostat is removed..... Regardless of what people say about this (not to say it isn't true, but....) I have always alleviated radiator problems in the summer by removing the thermostat. (I run a thermostat most of the time, this isn't something I do every year). The car always runs cooler and never overheats. It does run too cool, but I've never in my 30 years of driving, had a problem doing this. Nine times out of ten I needed a new radiator at the time due to blockages in the system. I ran my Elky without a thermostat for over a month last year with absolutely no problems. So while science says don't do it, real life says it's worked for me. (Also the system is still closed as long as the radiator cap is on). I've had better luck with radiators that don't have plastic panels on the end as in the aluminum ones. I find the AT lines fit better in metal and the constant heating and cooling of the system doesn't warp the metal as it can the plastic. Kelly C. Hanna El Camino Country www.hannawoodworks.com
