Guys, I got a 78 Cutlass that had a 305 Chevy in it. Putting in 350 Chevy. I don't have the original radiator anymore so I need to match up dimensions. Found numerous aluminum radiators on ebay at real nice prices but some had different dimensions from each other that said would fit. Anyone used any ebay all aluminum radiators? 2 row or 3? My 350 is just a dish piston and 76cc heads so its no big HP engine.
