[Go joe go!]

I have a blue thunder 427 medium riser intake and was going to use twin 450's (0-9776). But I have a chance to buy a matched pair of holley 1848's (465 cfm). I've been told that the stock linkage kit will bolt up easily to these. 450's have mechanical secondaries while the 465's have vaccum secondaries. Any one running dual quads, please let me know what you think is a better choice. Thanks
