What kinda carb is best for the first gen. I want to put a Holly on but i dont know how many CFM's it should be. Also, where can I get a template to bridge port a 12A?

 

If you want to go with a Holley get one from a rotary company that modifies them to work properly. They don't work as well as they could if you just slapped one on there. The size will still vary with your porting as well. You can get templates from Mazdatrix. They also have info on the Holley's on which one works best for certain porting configurations.
