Don't use a regular Holley on the 12A, It'll run like crap. I've tried it with a 650, 600 and 450cfm and it just won't run right. Use an RB only, It will run graet right out of the box.

Not true.....I have a 450 on mine now and it runs great. I've seen lots with 650's and they run great...my rb 465 was plagued by problems i replaced the pump diaprham every 3 months...
