I have a 350 bord30over, TRW Flattop pistons,RV type cam,194Heads,Edelbrock Performer intake, Edelbrock 750cfm Q-jet,MSD 8360 dist.,Blaster coil,Headman headers,K&N filter. With this type of engine, what should the initial timing be set at?? 4 ,8 ,10 ,?? After that I can switch the springs on my dist. to allow the mechanical advance to advance in a quick manner or a slower type of advance curve. Does anyone know what the TOTAL advance should be at a particular RPM??? Oh and the VAC advance should be pluged while I do this,right?? Any thought on this would be GREAT!! Burt4x4 Rock ON!
