gsc 272/272 profile and grind question
Hi i was just wondering what the specs were of the 272/272s that i have had in my car. i purchased them in very early 2006 (march) im not sure if any other grinds were updated of the 272 before the s1's came out
like lobe lift, duration, centerline, all that good stuff. most appreciated greg btw i dyno'd for the first time on a regular reading dyno (dyno dynamics = boo) i was tuned back in dec of 06 for full bolt ons and cams and then a few months after i installed an evo9 turbo and was never tuned. i was actually detuned by friends to be safe till i got a tune. they took timing out and made it richer. so technically im untuned and detuned. either way i put down 350whp and 330 tq on 23.5 psi on a mustang dyno. it reads like a dynojet. everyone with full bolt on srt's were dynoing in the 280-300whp range and an fpgreen pump gas sti dyno'd 344whp so im fairly sure it's calibrated to read like a dynojet. anyhow so these old as dirt cams of yours still kicked some a$s. i put down the most of any stock turbo'd car that day at turbochargers. com here in houston :) |
over a month has gone by. really greg?

I'm rocking the old skool GSC cams as well; can you say 264/272's. They make great power still and I have high hopes for the S2's I have sitting in the garage.
Greg, If you could provide the specs for the 264's, 272's , and 280's I would find it useful as well to see what I'm gaining by going bigger. |
there were a couple of different numbers used with the 272 and 264s and we moved the CL's quite a bit as well. can you guys give me range as to when you purchased these...
the GSC 280s 10.67mm peak lift intake and exhaust 230 duration @ .040" CL of 109 intake and 114 Exhaust |
i purchased mine in early to mid 2006

These are some #'s I've gathered from various places, need Greg's confirmation if correct though.
GSC 264 * 10.6 I/10.0 E 105°I/113°E GSC 272 * 10.6 I/10.0 E 105°I/113°E GSC S1 10.8 I/10.2 E 110°I/110°E GSC S2 11.2 I/11.0 E 107°I/113°E GSC S3 11.5 I/11.5 E 108°I/116°E * old school GSC cam, not as good as the latest S1/2/3's but there ain't nothing wrong with them |
