Hello,
I vaguely remember a thread about radiators, but I can't find it. I'm building an Olds 455 for my truck and I'm a bit concerned about cooling. I've noticed that I can move the passenger side radiator support about 1.5" apart, which would allow for a larger radiator. Would this be necessary?
Thanks,
Mikel
maybe not, but a very very good idea. Summit has aluminum dealies for like, a buck eighty? Spicer is running one in front of his 427, works great. I'd upgrade if it were me. Hahah Actually, I will be upgrading as I'm putting in a Buick 455 myself.
Yeah, mine works pretty good. It one of the aluminum jobbies with the flat wide cores instead of a traditional three or four core design. Twer I to do it again, I'd move the passenger side over further and put a wider unit in. You may as well go as big as you can now.
My rad support is in my basement right now. I had a look at it last night, and noticed that I could reverse the two "L" shaped rad support brakets and gain over 6 or 7" in width. The rad would of course be quite a bit wider than the front opening of the front panel, but with a good fan shroud, the cooling power would be crazy.
Ooops... On second thought, reversing the brackets won't work because the rad would hit the frame. :(
i was reading on novak adapters and they said that a radiator should be have a minimum square inch area as the cubic inch of the motor plus 50 more square inches for adequet cooling so with a 455 you in theory need 505 square inches to cool it "good enough" hope this helps. and btw the number of layers does noe matter just the surface area shown to the cool air and that is all. as the more layers the radiator has just means that the back (closest to the motor) has hotter air passing over it then the front most layer. any way for more info go to novak's site.
