REVERSE FLOW WATERPUMP?

[SY1096]

Ok Guys, don't throw stones at me. I have been so out of touch with engines and modifications for so many years I really don't know the answer. Can reverse flow water pump technology be applied to our 4.3 engines? If so, where can it be found, at what price and to what benefit? If anyone runs it, let me know what basically you had to do to make it work.

A lot would have to be changed.... coolant passages in the heads and deck of the block, thermostat placed in the bottom hose instead of the top hose, radiator flow, probably add a de-areation tank (Remove air from water) Head gaskets... alot of things.... you are not having cooling problems are you?

No I don't . I just thought there would be some cooling increases in the head area like the LT1 engine enjoys that may help when boost levels run higher. The way I understand the LT1 engines can run higher compression ratios because the water flows through the heads first. Which offers cooler water than passing through the block first. Just a thought.

The internal plumbing of an LT1 block and heads is waaaayy different than any other small block or 4.3.

Gm spent quite a bit of time and money to make the reverse flow cooling work, and it was a great idea. But I don't see how you could retrofit a 4.3 to work with it effectively for a decent cost.

Back in the late 80's and early 90's Richard Childress Racing (Dale Earnhardt) used this concept before GM introduced it on their automobile lineups. It allowed them to run higher compression ratios and timing setups than other teams were capable of doing. It was kept fairly quiet inside RCR for sometime. After it leaked out to other GM team owners ,Dale did not dominate as much as he did during that period. Not to say, that was all there was to his winning mind you, but I understand it was quite helpful.

I'm trying to grasp the differences that are that major and understand them. I would love to think the systems are not that much different other than direction of flow and thermostat location. But I just never have taken the time to investigate and learn.
