I want to build an NA motor with 350-450 rwhp. I'm thinking some VT stage III NA cams, some lightweight valves with a port job, titanium springs and retainers.

My questions for you guys are, 1. how much power would I end up with roughly with all that head work? I will probably build the motor a year or 2 after that, as i don't think my 102000 mile pistons will like ~500hp very much. 2. Are these good cams? Could I do much better? 3. Where are good places to find lightweight valves and titanium springs/retainers? 4. What else do you recommend to make a stout NA 32v motor? :

thanks for your help!

350 might be possible, but 450 is not! This will take a lot of money and it will be much cheaper to go FI!

BTW I just relized you have a 4V so it may be possible I dont have a clue with the 4VS!

highest ive seen NA is 430. a 4v will probably be your best bet for high NA hp, but it will still be hard and very costly, thats why people tend to resort to Forced Induction.

for a 2v esp. building your motor will definately be the NUMBER 1 thing on the list, along with some svo heads (port them they flow nice from what i hear) get a solid cam and a bullit intake (port this too lol) its gunna take alot including LTs strong tranny and rearend and alot of suspension to make it work...
