small block 350 in a 94 S10, It has a brand new radiator in it, however it is the same model as the one that came with the original 4.3 liter vortec. I went with this radiator because the guy at the shop said it would be more than capable. I have also installed two electric fans (1 ten inch and one 12 inch) in the front of the radiator (and yes they are both blowing not pulling). I swiched the original thermostat with a 180 degree one. temp climbs to 210 in just a few minutes. Could it just be that I do, in fact need a bigger radiator? or are there any other areas I would need to look into first? Thanks for any help
