I am thinking of upgrading my 88 bin and mask to an 89 bin and mask so I figured I would see what I could find while I am waiting for my ostrich and g1 adapter to come in the mail. I found an ANZA bin and I am not sure if this would be a good choice to start with, my engine is an 88 5.0 lb9 and stick shift and it has 3.08 gears, my computer is a 165, however the ANZA is listed for a firebird with California emissions, but otherwise is a good match. So I was wondering if I could get some input as to weather the ANZA bin would be a good choice as a starting point to tune my car thanks, Adam

 

Since you are tuning it, it doesnt really matter what you start with. Any 5.0 5spd bin would work but need to know if you have the peanut cam lb9 or the l98 cam lb9. Big difference. Match the bin to your model as close as you can with that in mind. g92 cars should all have the big cam. The rest of the bin information you can Edit to match.

 

the ANZA bin looks the closest except it is California emissions the two best matches are ANYR and APYX except I cannot find either of them yet, my car has the big cam .415 and .430 lift, I verified this when I measured the cam when I had the motor apart
