600hp From A 2v?

I currently am running an eaton m112 on a 2v. The 400hp is nice but now I'm looking to go more. I know I need a stronger bottom end. I'm very mechanical myself.....would I be better off buying a short block or building my block up with fitted internals.....I only have 63k on the odometer. I figure like a 3.4 whipple. Im pretty sure my fuel system will handle it...60lb injectors focus pump with bap. Other issues....trans...will the 3650 handle it or necessary t56 swap? Axles?
 
Go with a Centrifugal Blower and ditch the BAP. You should run a real fuel system, boost referenced on something like a Hobb's switch. A dual methanol system is also a good idea, if not a must IMO. I made around 700rwhp on 60lb injectors with meth. I don't have the log and can't remember the duty cycle. I stepped up to 72's to go in the mid 800's.

I've got a brand new blower here with tags on it that will work on your car. It will make 700+rwhp on a 2v.
