Owner of GM 350 HO looking for Miniram answers

As most of you know, The Gm 350 HO Crate has Vortec heads on them and from what I read TPIS makes the miniram to install on them. Just a couple of questions......1) How hard is it to take off existing TPI (w/ Vortec Manifold $400 :( ) and install the miniram??? 2) Since I have the Vortec manifold already...WOuld it be better for me to port out plenum, buy some TPIS runners and add a 52mm TB????? 3) If I do go with the mini, Can I just buy the intake and plenum and run my existing other accessories??? example: Fastchip, 21 lbs injectors, TPI fuel rails etc etc etc

Thanks Guys

I am going to do something......just trying to figure out which route is better. MONEY IS NO OBJECT....but ease of install IS!!! (being it is my daily driver)

The MiniRam is all one piece. You would have to get the fuel rails also. Everythings bolts right on and the 21lb injectors would work. What kind of 21lb injectors do you have? The factor injectors are 19 on a 305 or 22lb on a 350. You might want to go with a StealthRam as they are alot cheaper and are good pieces. Or get the SuperRam Lid, box and runners and use your intake. Check out my web page and you can check out my SuperRam and supercharger. The SuperRam is a very good system but hard to work with. I have seen the lid, box and runners for sale on Ebay.
