so what are your thoughts on reverse cooling? Big block 383/496 strictly race .

I know nothing about the BB but the SB seam to only be popular with the roundy round crowd. Where temp were high and had to deal with it for long period of time.

Its a lot of work for a drag race application. Just my o2.
Maybe super High HP it is and idea..........don't know
 
I got the old shogun system when I bought my old car as a roller. I gave up on it after a couple months because I could never get all of the air out of the system. The next time I seen the guy that sold me the car I told him about my plight. He chuckled and said “why do you think it came with the car!”

I worked for GM from 95 to 99 Chevy and 99 till 2008 for Cadillac and in 96 the LT4 that was in the Corvette had 10.8:1 CR. They did it by reverse cooling, it put the colder water on the combustion chambers to help cool them and stop pinging, and it worked very well. I would do it on a big block or a small block for that matter. The BB would be easier because of the ports, they put the water to the heads.
 
I am asking this question mainly because I have my engine hooked up for reverse cooling. To get it all burped. I have jacked up the front end, left and right side. Did this twice. The motor stays cool with pump on, but for some reason will still puke water into catch can. I have an 19-21lb stant racing cap. I have pressured the system to 18lbs without the car running. Holds pressure all day long. But like I noted with car running water gets past the cap. So I was thinking maybe it has something to do with reverse cooling.

Looks complex. What's the point?
 
I did reverse cooling as a suggestion from a couple of fellow old school drag racers. To cool heads first. I did research and the consensus was 50/50
 
compression getting into the cooling system??????
 
I thought that as well. But not sure how to check for that. When I manually pressurized the system I had the plugs out so I could hear any bubbling in cylinders. But it just held pressure.

you add the blue fluid into the tester and sniff you radiator. If your blue fluid turn GREEN! You Found Your Problem. Combustion gas in the radiator

Yeah, I know what it is and why, but my "what's the point" comment was saying why do it when a good conventional cooling system works well? IMO if reverse cooling is something you feel the "need" to do because of over heating, you probably have other problems.

I did it simply as a suggestion from a couple of experienced drag racer friends when I was building this. Figured it made sense so I will give it a shot
 
Cudafever thank you for the suggestion. I believe this is very valuable and will give it a go.
 
Not much more than a headset set and you can do that test a hundred time(i'm Exaggerating) with just one kit.
Check it now, fix leak, check it again..............any time you think the head gasket has failed..........answer is 10 sec. away!!!!!!!!

Rusty, reverse cooling puts the coolest water into the cylinder head. That should reduce combustion chamber temperature and help to reduce pinging. That would then have the potential to run more ignition advance, if what was being ran was not optimal and was being limited due to pre ignition.
Reverse cooling is like most performance tricks, not optimal for all and is something done in conjunction with something else,,,,

Yeah I know. But standard cooling works just fine, unless someone doesn't know what the heck they're doing. To me it's just trying to reinvent the wheel.

Reinventing the wheel led to much better wheels today, right !
Not a bad thing

You need a bleeder at the highest point of your cooling system so when you fill it up with coolant the air can get out, so air is not trapped in the system.

To be clear I pretty much know what I am doing. This reverse cooling thing was just to try something new

I understand. I wasn't trying to say YOU didn't.
