i have a big desel 3 core eadeator in my truck and its leeking pritey bad and i think its pritey pluged up to and thats why my trucks been running so hot

i called 1 800 raidaders and thay wanted $300 for a 4 core, i was thinking about sumits 31x19 in. aluminum radeader with 2 1in. cores it seas it will out cool a 4 core and i have 2500 cfm fans, do you think this will keep a 454 with cam, pistons, 750 carb, intake, header cool?,

i know its a bit smaller than mine but i dont think mine is doing mutch, summit sead it should be fine as long as its under 12 to 1 compreshon, i dont know what kind of pistons its got but ther hier comreshon,it will still run on 92 octane so its probley under 12 to 1?

what do you think?

The short water pump should sit pretty tight against the block, the long one will have a large gap behind it, almost enough to stick your hand down behind the water pump. Keep in mind this is looking straight down at the water pump from above.
