ok so i got an unbeatable deal on some gsc 264's that i couldnt pass up last week, im fixing to be installing full boltons, meth, ix turbo and cams. i am looking for a great daily driver cam that will still do major damage at the drag strip. i have been searching all morning and cant come up with an answere to my question, will these cams pack the punch im looking for or do i need to get the 272's. i like that these cams will give me good power off the line but not sure if they will give me what i need at the track through the powerband. do the 272 make more power and torque or just move it to a different spot in the power band.just would like to know your guys opinions on this, i dont wanna buy cams again unless its going to make a big difference. thanks alot guys

 

are these the S1's?

 

no its just the regular 264s i would definetly be happy with the s1's lol

 

well, GSC recommends running a 264-268 camshaft on a stock Turbo, if that helps. Also, here is a little comparison between the GSC 264 and 272's:

GSC 264
Advertised Duration - 268 deg
Effective Duration - 194 deg @ 1mm
Lift - 10.6mm Int / 10.0mm Exh
Lobe Centerlines - ___ deg Int / ___ deg Exh
LSA - ___ deg
Stock valve springs OK

GSC 272
Advertised Duration - 281 deg
Effective Duration - 203 deg @ 1mm
Lift - 10.6mm Int / 10.0mm Exh
Lobe Centerlines - ___ deg Int / ___ deg Exh
LSA - ___ deg
Stock valve springs OK

 

thanks for the info man still open to any opinions from people that have ran 272s or both thanks guys keep it coming
