Hello, I am currently looking for an oldtimer (Corvette, Firebird etc.). Now I have come across a Firebird of the first genration, which has various modifications. Before I lead big negotiations with the seller, I wanted to ask if you could get an H-mark here with the engine/gear. Without H such a vehicle is not really worth it. Verbaut is a 383 Stroker (I go from Chevy, is usually like that) with ceramic header, a 700R4 Gearbox and a 850cfm carburetor. Otherwise a few other little things, which should not fall into the weight. The vehicle is in an “original look”, only the engine compartment looks a bit more shiny 😉 Short and scarce: H-mark possible? Also about a workshop, not private. The conversion is younger than 20 years. Greetings
