Quote: Do you have to run the coil packs on these or would a crank trigger MSD type setup work?
The engine comes with a crank sensor and a cam sensor built in. The standard MSD systems I have seen only drive up to four coils, and the standard crank trigger stuff still uses a distributor to send the spark. However, MSD does make a plug in kit for the LS1 and LS6 engine with a carb which can use the GM coils or the MSD replacement coils. I would suggest calling them and seeing if they are interested, I think that the development time for them on 5.7L would be minimal considering the similarities with the LS1/LS6 electronically. Depending on the sensors it may be something as simple as a different harness.
