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

compression getting into the cooling system??????
Its as simple as this.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.
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
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 shotYeah, 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.
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.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?

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.
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. View attachment 1715506370
Reinventing the wheel led to much better wheels today, right !
Not a bad thing
On a big block with trick flow 270's where would that high point be?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 newYeah 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.
