You're very right. My mistake, I Just know 1994 is the best year for the RMW. It has the LT1 with a towing package and the nicer dash with real gauges.

I forgot to update this post! The tach problem became glaringly obvious when I looked at the wiring diagram. It was because I forgot to reattach the timing connector. You are supposed to unplug it to do the timing and it directly feeds the tach. Surprising, I have no idea what it really is for. The car is working beautifully though!
