I,m running blade carbs with a 30bhp increase including vernier pulley, 24bhp from the carbs and 6bhp from the pulley. To give you a starting point you want 2psi fuel pressure and my carbs are jetted to 1.3mm mains with blanked off air correctors. 12deg of advance on dizzy. I,m using the gbs manifold.
My car was set up on the dyno and this set up produced the most power and torque the car fuels properly all the way through the rev range pulls from low down and revs its nuts off higher up
Good luck there is a lot of different ideas on how to set them up but this works really well for my engine.
