I've got a 94 GT 331 stroker, D1 procharger 13psi boost, alluminium radiator and lots of other goodies, heres the problem the cars temp gauge shows to be hot and peg out sometimes when you run hard through the gears and blows coolant out, but you can open the hood and grab the radiator and its cool not hot at all. Just tonight I took a friend for a ride and it blew a radiator hose off, seems like to me there may be alot of pressure on the cooling system. Could this mean I have a blown head gasket? Need help if anyone needs more info let me know.
