should i go with a 306 or stay with my 302 302 is low mileage motor with a cam with .494/.503 lift at 112,double roller TC 306 is a 7000 mile motor with 9.5:1 forged pistons, main girdle,TFS1 cam,new timing cover,new TC, new oil pump, new hardend pump shaft and ARP studs right now the motor is about 9.8:1 CR the new motor with those pistons ill take my CR up to about 10.3:1 but he does have another set of pistons that are 10.1 now and that will take me up to 10.8:1 what you guys think, throw my heads back on the 302 and see how that motor runs or go with the 306 and make more power ---
