Hiya, Just wondering do you know anything about ignition timing and how to adjust them? Also just wondering about if I need to make the ports bigger or anything after ive finished with this engine I'm building, I'm planning on a stage 6 crank, stage 6 racing 70's and pro replica, Thank you for any advice and help
Stage 6 racing is strong enough without porting. Stage 6 racing is stronger midrace kit, so no need for further tuning or adaptations of the cylinder. Only Stage 6 replica is not enough for the cylinder. Is too weak. You need Stage 6 Pro exhaust.
