im glad chevy has decided to continue on with pushrods. but i feel like pushrod tech has reached its limits for our life time with oem and they will be moving to ohc within 10 years.

they are already direct injecting. which we will never see as long as we have bbc in our boats.

As Gimme mentioned, if you want to run sequential, you need to have a cam position sensor. In the case of the Mefi, the cam sensor allows you to run 2 knock sensors and have individual cylinder knock retard. With the Mefi, we make a 1x cam sensor that takes the place of the distributor. I'm not sure what the Holley uses. Haxby could better answer that. You can have DIS without the cam sensor, but it's so easy to incorporate it. There are some that are commercially available. I just didn't really care for them. The have a cast housing with a stamped steel wheel. They just look cheap to me. That's why we did a billet aluminum piece. It has a larger shaft, sealed roller bearings, the wheel is hard coat anodized, etc. Obviously, it costs more than the cast one, but I think it's worth it.

I just checked the settings in the software - Very configurable. You can choose to go waste fire with the coil packs, or individual coil on plug. Holley loosely recommends one of the cast type housings Eddie was talking about - I agree, cheap looking. Eddie's piece looks very nice.
