Locking Down the Details on the 427 Build (Finally) and Evans Coolant

[CaptB]

Had a good call with Mike Forte yesterday after the block that was aquired for the 427 he's building me had arrived.

As we were talking through components, I asked him if the FFR supplied overlflow tank and radiator cap was sufficient for the build. He advised that he recommends something called Evans Coolant and that it basically negates the need for an overflow tank (will of course, still install one) as that coolant does not expand under the heat.

So I'm not here telling you that it's what you should buy, but I will tell you I asked him to include some in my order.

Maybe those who have used it before can chime in here.

The good news of the call is that the block has finally been aquired. The bad news is since it's a World Products block, a lot of machining will have to be done to it. Since the rotating assembly isn't in and there's a backup at the machine shop the best guess estimate is the end of summer on delvery. All good, this "stuff" we do just takes time in the world that we have going on.

Have a great Memorial Day this weekend and honor those who have sacrificed so we can have our hobby.

Capt. B,

I've run Evans. Was in 2nd SPF that I purchased.

It's good stuff but I'll never run it again.

It's an oil-based coolant, expensive, messy if you ever need to remove it or work on the cooling system. It might cause track officials some concern. Unlike standard coolant you don't find it everywhere. If you choose to change back to a Glycol based coolant there is an extensive flush routine as Evans and Glycol don't mix.

On the upside it lubricates waterpumps well, it does cool well, no pressure build-up or at least very little. If you never take your system apart it seems to be a great alternative to Glycol based coolants. It's a great rust inhibitor for blocks, heads and cooling components.

My evaluation is based on the way I function. I take things apart, run on the track, break stuff, push all normal limits. Friends that built parts used me as a "crash dummy" to test their new stuff. I also ran cross country multiple times, long distance to track events and LCS 5-6 times.

For me, I'll stick with a good Glycol based coolant, distilled water and an additive like RedLine Water Wetter or Royal Purple Purple Ice. Never had a cooling problem as long as I was moving.

Hope I helped.
