Hi Mike;
Its a bored and stroked 289, measures 331. I have been struggling with the overheating for three seasons and have been applying the tried and true Tiger cooling fixes one by one. Blocked the horn holes, added a rad spoiler, put a spring into the lower rad hose, as well as refitted the by-pass hose, etc. What I haven’t done was have the rad cleaned and rodded, or replaced the 13" Flex-O-Lite fan.
In a final fit I bought this rad from a guy California, so I don’t know the manufacturer, but it is a handsomel piece. Its very well made, beautiful welds and fittings, pre-drilled brackets and the over-all dimensions are exactly the same as my stock rad except for the thickness. I also ordered from Summit a new Miloden stock replacement water pump, a 14" mechanical fan, a 11" electric pusher fan and a temp-sensor switch and harness.
I was disappointed to find the lack of clearance between the steering rack and the rad bulkhead-mount.
Since I started this post, I have been looking at the related parts, and am considering applying some ignorance to the lower part of that bulkhead. I might just be able to move it the 1" I need to gain enough clearance.
I have also checked the measurement from the waterpump mount to the rad if I can get it installed. Using my stock water pump I will have about 1/2" clearance. Scary. I hope the Miloden is no thicker.
