This is good information.
So what about a shorter duration cam, say 218 @.050" but with a tight LSA 106? Is the burn still going to be sluggish at idle? I ask because thats what I have and I have my timing at 19 initial, no vacuum adv and total thats about 37-38 all in at 3k. I bumped it to 3,500 rpm but dont notice much of a difference. Btw I have a saginaw 4 spd with 2.73s for now. I haven't yet but was wondering if going to 2500 rpm would make a difference. Its a heavier car GMC caballero 78' (el camino). Also, would you recommend higher initial timing if the engine will tolerate it? thanks
