Im looking to add one more piece to my engine. Im running a mild 289 and would like to add an over flow, one of the nice stainless cylinder types. Does any one have any pros or cons to this? Also which size should I get? 13in., 15in.,17.in? Hows the install? Any custom brackets needed etc? Also I noticed on the over flows they have for sale, they have two posts coming out of the bottom. How do these get hooked up to my radiator?

Thanks!

I think these overflows look very nice and I can't think of any "cons" to doing this.

As far as the length goes the more capacity the better, to a point anyway, go with the biggest one you can install without fit issues.

I would imagine that they come with some type of "flexible" brackets that should accommodate simple mounting to the radiator support or even to the radiator mounting bolts.

(Flexible = ability to move around for different mounting options, not elasticity)

UBY289

I think I installed a 16 inch long one on my 67 Coupe. It easy to do and install.

I put on two 3" * 10" cylinders. One for the radiator and one for washer fluid. I mounted them side by side on the drivers front apron. Each tube has two holes, one that extends down to hook up to the radiator/wahser hose and one that is an overflow. The overflow one extends up in the cylinder and stops a couple inches from the top.

On the washer fluid tube I put silicon in the drain tube then drilled a small vent hole in the back toward the top to act as a vent. They look pretty slick and work well. I found it easier to mount the 10" tubes on the apron because of clearance problems of the longer 2" tubes.

The metal tabs on the back of the tubes attach to other tabs that are supplied in the kits and then bolt to the car. Very easy to install.

did you have a stock radiator with a 289 for your application?

68EFIvert

My car had a 6 banger when I bought it so I upgraded to an aluminum unit. The engine is now a 5.0 EFI engine with a Vortech Supercharger. It is made by Northern. I had to fabricate some mounts but the price was right, less than $200 for the radiator. I also wanted a radiator with inlet on passenger side and outlet on drivers but you can get radiators configured almost any way you need. The Northern fit the bill. Let me know if you need a picture.

Some people say its very hard to mount these, is this right? I called NPD and they said the over flows are returned quite a bit for not fitting up with the radiator.

Again, mild 289, stock radiator

do you have a shroud?

I have a stock radiator in my 66. there are 4 brackets that fit in the standard radiator to support panel holes. The shroud bolts onto the other end of thesebrackets.

my overflow bottle didnt come with any specific brackets but it had 2 tabs on the side that just happened to line up with the shroud holes...fitted easy.

so, if you have a shroud, measure the distance between the bolt holes on the drivers side (I think in a 67 your battery tray may interfere on the passenger side)

Ask the guy you are dealing with to tell you the distance between the holes on the overflow bottle and compare.

If you dont have a shroud, you can make the brackets to suit the bottle...pretty basic as not much weight involved.

btw, mine is 13" but actually longer when you add the inlet and outlet holes on the bottom of the bottle (about 3" long which you need to take into account). Thats the 2 "posts" you see in the pic. You just use rubber hose from your rad cap overflow outlet (just under the cap) to the bottle and another from the bottle to the ground in case of overflow..

you dont need a great big bottle fora stock radiator cos it only spits out a little then sucks it back in whenthe carcools down anyway. You do need a recovery type rad cap.

mine is all in pieces at the moment so pm me if you want pics and i can get them over the weekend.

good luck

The cylinder I got from NPD has two tabs on it and is supplied with two mount which are like short 'L' brackets. You can either bolt the two 'L' bracket to something or do as I did and place a few small tack welds and mate them to the radiator support. Any way you cut it, it is not a difficult install but is not likely to be just a bolt-in either. The only con to the install I guess would be the cost compared to a cheapie plastic one.

I'd do it again.
