i currently have a 300h.p. 350 in the car now with what appears to be a stock radiator. i have recently acquired a 383 stroker w/ rollercam, lifters,rockers,194 afr heads, i was told the motor was rated in excess of 425h.p. with the new motor will it be necessary to replace the existing radiator ? i am working with a budget but if it requires a new rad. then so be it .

If you have a temp gauge try it with the old radiator and see. Just watch the temp gauge with the new motor and if it starts getting hot (like 200-215 degrees) shut it down and get a new radiator.

I personally think you would be OK with a 3 core stock radiator and a 383 as long as the radiator is in good shape. A 2 core radiator would be pushing it and you will probably overheat.

A GOOD fan and shroud will be needed as well. If your shroud is cracked or damaged at all it may be more of a problem than the radiator. [img]smile.gif[/img]
