LS1 coil DIS ?

[jjorgensen52]

since when I first put the Ty together I used regular ignition to get it running, I'm now gearing up to finish it by swapping to LS1 coils (already have the harness wired and everything). Rather than add a crank trigger and have to machine my dampener, I'm thinking about simply swapping the timing cover to a new style (and drilling the 6 extra holes in the cover) with the crank sensor, pressing the reluctor wheel on there and using a newer style short snout balancer. I have an MSD cam sync for the truck on the cam side.
Anybody ever tried / heard of this?

I am aware of that setup, but I'm looking to move away from the stock dist, partly because I have the MSD cam sync sitting right here, and partly because I am not impressed with the fit / finish of the dist that I have and don't want to shell out more $$$ for a nice one.

That said, with the cam sync and a newer style 4.3 cover, I'm still looking at only about $550 to do the whole setup, unless I buy the cover, sensor and balancer brand new (to which there is really no point, the covers are ABS and don't deteriorate, and the balancer won't be much worse)

I admit, the wiring is a little less plug and play, but I'm not really going to argue that. Just looking to work with what I have and keep options open

Re: LS1 coil DIS ?

After some research, I know the following:
-Plastic covers require a little more work to seal properly (but can be done)
-Vortec reluctor wheel does fit on the older style crank (just need the 3x one and not the later style 58x one)
-Double roller timing chains and reluctor wheels do not like each other. Specifically, because the reluctor wheel is no longer centered on the CPS.

So, this setup will work 100% with a stock motor.

For my motor, I now have a problem, that is the fact that I'm running a double roller Edelbrock performer timing chain. Judging by the shape of the sensor boss on the plastic cover, if I buy the cheaper cover (which has the boss, but not the sensor hole) and then drill the sensor hole offset the appropriate amount to center the CPS on the reluctor, I am all good.
