I am about to swap an LS7 into my 5th gen Camaro SS(again). First motor was GM crate 570.

I want to avoid mistakes with that foray.

What cooling should be done for Heads, Cam, MSD intake manfold?

What 4 point steam ports kit will work with the MSD? I am particularly concerned with the Cylinders 7 and 8 at the rear as number 7 was the loss. Instead of using a kit at that time, the rear ports were blocked off and I think either heat or detonation(fueling) became the issue after 6k miles.

Is an aftermarket radiator helpful for cooling the entire block? Which one would fit?

Fans: Is turning on the fans sooner also enough?

What else? I have an aftermarket oil cooler currently which I would be utilizing.

 

I doubt the steam ports caused your engine failure. Me and many others beat on them boosted with no steam ports in back...

For fan I would get the brushless one from a newer zl1..they are beast

 

From a quick search, the LS7 powered z/28 5th gen had a different radiator than either of the other v8 cars.

For your first engine loss, was it cooling related or was it valve related?

 

7 and 8 will run the hottest. If you run EFI, maybe a degree less timing or a bit more fuel in those cylinders.

 

Check out Fffaster on eBay for good 4 corner steam kits. Has quite a variety Yes go as big as possible on all the cooling and like Psnneton said, watch the tune.

 

Not quiet sure. But heat must have been an issue.

At 3k I did the heads. When they were removed the shop called me and said the cylinders were rusted! He had never seen that before.

They wet sanded and installed the heads with block off for the rear.

 

Will a fan change make that much of a difference vs. turning the stocks on sooner?

What about cooling the back of the motor?
