Do you have problems with cooling? I'm putting a twin cam lotus engine and box in. Thanks.
I have not seen any posts on this forum ( but I may have missed one - if any ) about overheating.
The engine size / power should not matter as most keep Eagle SS's to 2 litre.( assume yours is no bigger than 2000 cc )
However, in order for mine to never overheat ( not that it would ) have a look at the 2 pics.
There is a vent cut in the front of the bonnet bulge, and 2 additional ones at front lower edge.
Mine is not a modified engine, although in it's time had 4 carbs on it ( 2 x twin weber 40 dcoe ) side draught. jetted for an RS 2000 ( that's the way they came )
Leave the normal engine fan on it ( as mine has ) but ensure you have a temperature guage and manual electric fan that comes on with switch, as if the coolant sender for the fan ever stops working ( it's known to happen ) you may think everyting is o.k. when it may not be.
Anyway, run your car without holes in bonett and see how it goes first.

P.S.
Plenty of room for electric fan in front of radiator. Just get one that blows the correct way if mounted forward of the radiator.

My car has a removable front bumper so I have decided to cut a hole where the front number plate would go in line with the fog / spot lamps and put a grill behind. I will then cut a slightly larger hole in the front panel and fit an electric fan. The engine and box are from a lotus eclat so I think that should be enough cooling. Paul.

My car has a removable front bumper so I have decided to cut a hole where the front number plate would go in line with the fog / spot lamps and put a grill behind. I will then cut a slightly larger hole in the front panel and fit an electric fan. The engine and box are from a lotus eclat so I think that should be enough cooling. Paul. Attached are 4 photos ( 3 of a Racing SS, Ford V6 front engine.) Racing SS - This engine would be thrashed, so needs decent cooling, but yours wont be running at full throttle permanently !
The front of the SS forward of the radiator is completely open at the bottom, but if you are going to be running at full throttle permanently. you need to cover the bottom to direct the airflow to the radiator from the front of the car: A hole where the front number plate was will get mixed with the air flowing under the car and would probably be sucked out under the car and not reach the radiator with no under-tray.
Even production cars have underbody composite shields, under front to front of radiator and older cars have ( did have ) tinware directing air to the radiator. If you are really worried about overheating you should fit an under-tray from front to the bottom of the radiator. and tinware to direct the airflow to the Rad'.
But I don't think you will need an under-tray for normal driving. I don't have one. and no problems with normal driving over 6000 miles in it's life of ( 28 years off the road currently ) and compression testing recently, was still within manufactures spec's
I run the engine up to operating temperature - see the temp rise then fall - often in those years, and at ( 1500 minimum ) 2000 revs, then when finished - at 3000 revs for 1 minute, to clear out the engine and exhaust.
But whatever you choose to do, will keep the cooling on track.

Clarrification to post one comment
I run the engine up to operating temperature - see the temp rise then fall - often in those years, and at 2000 revs, ( 1500 till 50 degrees C reached ) then when finished - at 3000 revs for 1 minute, to clear out the engine and exhaust.
This is when the car never goes out on the road, e.g. it's on wheeled stands, or has parts removed for repair / renewal etc. You idealy need to run an engine once a week, AND fill carb with 99 octane fuel as that's only E5 fuel, and with 2-stroke oil added.
A) To stop mosture
B) stops rust forming between piston rings and bore. C) a 30:1 ratio 2-stroke oil added.will be fine. D) helps keep Battery cycled, and lasts a bit longer than 1 to 2 years max when a battery is not working correcty by infrequent use.
Once a month engine start is acceptable, ( 3 months max.)
Find Reliable Unleaded Fuel ( see canberradiamondblade.com.au/how-to-mix-2-stroke-fuel/ )
This part is vital.You need to find and use a reliable unleaded fuel. There are specific things you need to look for. For instance, it should never comprise more than 10% ethanol. Why? Well, when exposed to air, ethanol attracts moisture. And as you probably already know, when water mixes into an oil its properties change, so it no longer has the desired effect.

I have cut the bumper and front panel and that will be plenty of air plus I will probably put two fans if necessary. I have several lotus cars, both n/a and turbo. Also a supercharged Midas. I use CVL turbo additive in the fuel and I have no problem with leaving fuel in them at all times. I do tend to start them all every month or two. I was worried when they brought out the E10 but so no problem.

Below is a Drag car, but ref is to driving normally - an over-powered engine - on the road. 260 degrees mentioned, is 127 degrees C - when normal temp is 90 degrees C ( 194 F )
Water boils at 212 degrees F ( 100 C ) but pressurise at 7 lb above norm raises that to 111 C ( 232 F )
pressurise at 14 lb above norm raises that to 120 C ( 248 F )
That's why your radiator is presurised, ( to raise the boiling point )

Prior two posts ( above ) to this, now have the web site shown and link working.
Thanks.
