Well I just took delivery of the radiator. All looks good. It is a huge 2 core. Total core width is almost 2 1/2" that should have no problem keeping this engine cool and should work down the road when the 305 is done and I go to something larger and higher output.
I've ordered the wider big block radiator isolators which should be here tomorrow. I need to be sure to grab some heater hose and a new radiator cap so I can change those out (radiator hoses and T-stat were done last year) and do a good flush. I've flushed it before, but as long as I've had the truck the coolant has that kind of old harsh smell to it, and I wanna make sure that's gone. Maybe I should toss a bottle of flush in drive it for a few days.... I'll think on that a little. The soonest I think I'd be able to do the replacement would be Friday at the farm so gives me a little time to get my stuff together.
