It is tuned in compliance to the Appendix K and the way the Group 3 cars were made back in the day. B18, double Weber Carburetors and custom exhaust manifold. It flashes at 7000 rpm. Sounds cool with your project ;)

@@krarupnielsen-vintageracing16 Now I need to look up the specs for Group 3 and Appendix K. Just for knowledge, of course. I don't think a swap from the stock dual carbs to Webers is in my future. I think my Dad did that with his , back in the 60s. He always said he could rev the engine until the valves started to float.
