ZZ3/4 eprom in the LB9?
I will be putting the ZZ3 cam in. I will be porting stock heads and installing w/bigger valves. Porting intake too.
My question is:
- could I just buy the Eprom from the ZZ3/4 engine and put it in?
If i replace the knock sensor and spark module with the 350 one would it work better than my stock 305 TPI EPROM?
What do you guys think?

The chip for the ZZ3/4 engine is for a computer-controlled Q-Jet, not TPI, so it won't work at all. Your best bet is to start with the ARAP chip (or just the bin) and burn your own. Installing the 350 knock sensor and module is a good idea.
