pretty much as description states...

Car is 2000 Z M6. Loudmouth & Lid. Doing LT's & like boltons and going with a set of fully CNC'd 241's. TEA is 3hrs from me. Leaning that way as i can pickup/deliver heads myself. AI also in the running. Likely gonna be tuned by New Era (~3hrs from me).

Don't really care if i have to flycut...but would rather know before getting too far into it. If it's needed for sure id want to know so i can order the cutters too...if it's not required...bonus...

Question Applies not only to StreetSweeper but also "similar" cams with like duration/lift/LSA...

If specific grinds would clear )IE on a 114 but not 111) please specify that as well...

Not sure which Streetsweeper you are looking at, but I installed the smaller one (mid-220's duration) without flycutting. Cam performs very well and is on a 112 LSA.

looking at Cam shafts in the ballpark of the original street sweeper... so mid / hi 230's

With my setup, a 402 with -3cc reliefs in the pistons and PRC237 heads (2.1" Intake 1.6" Exhaust), I'm showing ~.275 ptv on the exhaust valve at 10* BTDC and ~.250 on the Intake at 10* ATDC.

This is with a SSD-14 (236/244 114+2 with .631 lift)

Forgot to mention this was with 68cc chambers and no headgsket

Possibly with a stock shortblock, as most of those cams will clear (with pretty tight clearances). But if you do anything with the heads, you'll probably need to measure.

I'd go ahead and cut just so you have room. Measure to know how much to cut.

If i wouldn't have found good cores for so cheap i wouldn't even be touching the car...it's supposed to be left "stock" til long after i sell my GP GXP.

It will remain stock shortblock. H/C/I only. I have more than a few shops pretty close to me so i could always make phone calls but often times im on the road so much this is way easier.

Initial blueprint was TEA CNC 241's or AI HCR 219cc 241's with a matched cam. AI claims 440-470whp is possible while TEA doesn't specifically mention estimates although almost every TEA customer i've seen is 430+ rwhp and very satisfied with the work.

The camshaft seems to be the worst damn part to select...with more than a few things to be concerned about...I just care that it is matched to the heads and the "system" with supporting mods gets close to the claims they make and typical results experienced by the community. General consensus is either company with a proper cam and bolt ons should be good for 425-475whp...and thats plenty for me until i get a 12 bolt or 9" under the car.

Then why not contact Ed directly and get his input?

How can you qualify "another" cam similar to the Original StreetSweeper???

If you try to ask Comp-Cams about what lobes Ed Curtis is using on his camshaft...I know the answer, and obviously you don't...

Event timing will dictate PtV clearance (not only the 0.050#!!!)

The original SS is a 236/240, but there are variants. In all honesty, why not let Ed spec the cam FOR you? He's worked with both TEA and AI in the past, and knows the cam events to appropriately match the heads at given lift.

Email Ed and tell him what you're doing, and see what he recommends.
