What everbrand cams you get, keep the lift around .500 with a long duration. And try to get some lond tubes to compliment them cams.

ive heard to get 270s. wut can u tell me about those? and would they be good?
Just remember to keep as much lsa (lobe seperation angle) as possible.. 112lsa minimum.. or the computer won't like it very much.
270deg duration would be a pretty top-end camshaft to go with.. Make sure with those cams to research how much lift is on the cam, get good valve springs to handle the lift.

I personally think that 270's are a little bit much to use for a street car. Is this your daily driver? If so i'd go with a little bit of a milder cam. And make sure you get it tuned.

I have the 274's, and i enjoy driving my car everywhere. Driveability went up when i switched to the pi's, i personally may consider the 270's, just to bring power on a little earlier.

When my PI motor ran, it had no problems under 3500, but once it hit at 3500 it hit and it ran well. It was almost like the nitrous was hitting in on this NPI motor...

it technically was, but it was a comp 270 with the advance out of it. SO a staright up 270, the grind i wanted was going to cause me to do fly cuts, and To properly do that IMO is to take the pistons out, whcih i didnt want to do at that time.

The Combination will determine the driveability. A npi motor with a pi swap will have more compression which helps. When the description says you need 3.55+ gears and computer tuning, you probably should have those things.
