Need suggestions for 4.6 build

[maxpower]

hey guys i just wanted your opinion on a few things. Currently i am building a 4.6 non pi motor with pi heads and intake. my quesiton is cam choice. this will be a all motor build and i am looking at the vt stage 2 cams. http://www.vtengines.com/store/index.php?main_page=product_info&cPath=11_1_8&products_id=2

i was also planning on using high load crower spring http://www.vtengines.com/store/index.php?main_page=product_info&products_id=1541

and jsut steel retainers becuase the cams are going to drain me of alot of cash. http://www.vtengines.com/store/index.php?main_page=product_info&cPath=11_1_6&products_id=1519. ].

does anyone have these cams? Another question i had was will there be any concern with PVC with the big cams and the PI conversion. i know the compression will be at like 10.5:1 with the swap. If anyone has any input, suggestions, or think this is a good setup please let me know. thank you for your time.

sounds like a good setup

alot of people on here running VT cams with no problems and i don't see why the PCV system would be of any concern, of course if the car has 70,000 miles on it you might want to change the pcv valve anyway

sorry, i just thought you got your letters mixed up (pretty normal occurance around here)

as far as your actual PVC concern, i'd like to know as well

im pretty sure there are no piston to valve problems with that cam even with a non pi piston.i have those cams but i also have a lot of other stuff too and my pistons are dished.id say to go with it though,pretty desirable cams and makes good power.deff need the springs though for sure.

Ok, I got a hold of VT cams today and they said that there will not be any problem with PTV contact since their cams do not have any advance in the grind, some high lift cams have up to 6 deg. Also the high load springs are a good idea just to be safe.
