When Pete had his 80 305 we dynoed Sunoco110,C12,C11 and even tried C25 ($20+ gal.at the time).The C11 was worth about 5,it liked to be 1 step richer on the sec. rod. over the C12 and the 110.The C25 came around after changing timing, jets,rods,moving the cam.In the end it showed a couple of HP over the C11.Some guys were seeing close to 10 on BBC.On the SBC the minimal gains did not justify the cost.So C11 it was! gsa612.
