I know the 264 duration cams are better for the street and the 272 duration cams are for race. Everyone is building a "race" car in their mind, sure. But if you care about a silky smooth idle, get the street cams. Don't buy the 272s and run to a message board and whine about the lumpity idle. If you think you have a street/race car... get the 264 intake and the 272 exhaust. It is a nice compromise.

 

if you're gonna have the lump... might as well have all the lump and all the potential. 272 revs safe up to 9k, at least with upgraded valvetrain. but it could be that it runs 9k without too... i just happen to know someone is running 9k with. now with stock rev limiter you'll have no problems revving as high as stock will let you on 272.

HAHA yeo... i think you need to quote the rre website for that one.
