Griffin stand up radiator Write-Up/How-To with part #'s
Alright so I did a lot of research on this before starting. Figured I will help the next guy and make a write up on how to do a stand up radiator with all the info needed.
Parts needed:
Griffin Radiator- Part # GRI-1-55241-XS $270 shipped from Summit Racing
https://www.summitracing.com/parts/gri-1-55241-xs
Upper Radiator Hose- Your stock upper radiator hose will work perfect. If you want to get a new one part # Goodyear 62426
Lower Radiator Hose- NBH FM68 16.5" x 1-3/4 Flex Hose. $20 at Napa
https://www.napaonline.com/napa/en/p/NBGFM68/NBGFM68
Lower Rad Hose to WP Adap- NBH 901 1 3/4 - 1 1/2 adapter. $8 at Napa
https://www.napaonline.com/napa/en/p/NBG901/NBG901
Fans- 2 Derale fans. Part # 16925. $130 each from Summit racing
https://www.summitracing.com/parts/der-16925
Barb fitting for steam port off heads- 1/2" Aluminium Male Weld On Barb Fitting Bung. Just google or ebay that exactly. Got it from ebay for $8 shipped
Bottom Rubber mounts for radiator to sit on- Bought 2" square rubber mounts and 1 3/4" circle rubber mounts from menards for $3.
EDIT: I used Weld on threaded Aluminum bungs 1/2-13 pitch that I found on ebay.
Straps for radiator- Bought 3ft of square aluminum from menards for $5
Tools needed:
Die Grinder/buffer
Screw driver
Tape measure
Straight edge
Drain pan
Paint pen
1. First off Disconnect the battery. I went ahead and removed the battery because it was kind of in the way. Remove radiator shroud. Drain antifreeze and remove all the hoses. Remove your fans and radiator.
2. Now your ready to do your measurements, mark where you want to cut, and start cutting. The radiator is 27.5" x 2.5" so I cut a 28" x 2.5" slot for the radiator. Make sure to make straight lines with a paint pen before you cut so it's all straight and looks good.
There are "humps" on either side of the radiator I pointed it out in the pic below.
Measure 2.5" in from each hump and make a line with straight edge. 2.5" in from each hump will make your total cut 28".
Then measure 2.5" for the width of the rad. Draw all your lines on using a straight edge and a paint pen and start cutting just like the first picture above shows.
Here it is with the radiator in. Fits perfect. Couldn't be happier with the outcome. I can actually see my turbo when I pop the hood which is awesome!
Bought these rubber floor protectors from menards and screwed them on where I wanted radiator to sit
Attached the fans with supplied hardware and wire them up.
Got the bung fittings welded on top of the radiator. Cut the straps to fit and mounted the radiator

Thanks for the write up. I'd been meaning to look this up this very topic, since putting on twins late this year. Have you driven it around in traffic? How are your temps? I moved my stock fans in front of the stock radiator and wired them as pushers. They cool great but howl quite a bit since the fans are running in the opposite direction(thick side of the blade hits the air first).
