Afternoon all. Have been building a NA vr6 motor for a while now, but sudden change of heart has made me want to strap a GT35 to it The predicament is i have brand new 2.9 pistons and block, so i dont want to splash out on pistons/block machining again. So my question is how much boost can standard pistons with H beam rods hold with a spacer gasket? Or Does the standard pistons fail before the standard rods? I already have Schrick big valve head, high tensile valve springs and 268s to go with it. Thanks in advance
