first of all a real peaceful 2017 for all.. I think, I have to re-jet my HIF6 carbs, when I have finished the work on my engine. It´s the standard 3.5 ltr engine and I have changed now the following components : SD1 heads, ports enlarged, standard valves. Will skim them by 0,5-0,6 mm, so CR will be around 9.8. Camshaft will be from the 3.9. Inlet manifold ports enlarged, airfilter adapters for the carbs ported. Will replace air filters with K+N (after MOT/TÜV...) and use them with the elbows. Does anyone have an advice for the main jets ?
