your cam at .05 is around 206/212 I would bet.

in regards to dyno numbers, it all depends on cam size and other mods, and those depend on how you use your car.

my z28 is strickly a weekend toy and race car.

if your car is a daily driver, the cam you got is a great choice.

My cam is not for daily driving or stealth..

I would think your car with a good tune, pending the dyno could be around 370-385rwhp...

congrats on the car and mods... as said earlier dont get caught up in the dyno hp wars...

I lost HP on the dyno when I installed strange dana s60 with 4.10 gears in my car, however the 4.10 made up for the hp loss with faster times at the track!!!

That's right about what I was expecting bane..

I would be pretty surprised however if it saw 370rw.. I could see 350.. With lts I could see closer to 370.
But stock converter and gears will let It read a few higher as well.

Nice guess bane, right on!

That is an extremely small cam. Almost to the point of not worth to me. However there are also some ls6 cam cars, also very small which came in c5zo6s, that run extremely good, so dont get down on yourself about It.

I would look at getting a 3600-4000 converter in the near future. That coupled with longtubes and a cutout would be a very nice gain.
Is your trottle body ported?

Who did the work installing/telling you what to buy/tuning.

A new torque converter will give you most out of your set-up. I suggest that be your next mod. Personally I think it will be close race against stock cobra with a decent driver.

Send it to New Era Performance. They do throttle body porting. Theyre a vendor here. Mike and his crew are awesome. I think its only $75 too.

Don't do that again!

If you need help with what to do with your car/next mod to get/what brand/etc... Come on here and make a thread about it. That is why this website is here. There are thousands of people 100Xs more knowledgeable on ls1s than the tech support at summit racing.
Did you get springs/push rods/timing chain/oil pump?
They had good intentions I'm sure, they just went about it all wrong. Your setup could have been a lot better suited for what you are wanting for the same amount of money I'm sure, aka the shorty headers.

I doubt you will hit 380Rwhp with those mods, it would have to be on a pretty generous dyno. I personally would give it 350Rw TOPS. The shorty headers certainly aren't helping either.

I already said it earlier.. It is a small cam, just like the ls6. There are plenty of people in the mid 11s@115+ with the ls6 cam. However they do have full bolt ons/some have ls6 (243 casting number) heads/along with some weight reduction and a nice converter. MikeG is one of the first that come to mind (pretty sure that is his name, SOM Z28 IIRC).
If you want to make the most out of this cam, you need to get a nice set of heads in my opinion. Something like the AFR 205s. You can pick them up for around 1500-1900$ used with springs and cleaned.

Who did your tuning?

mild cam (comp cams), w/ valve spring kit, Edelbrock shortys Headrs, no Cats, flowmaster 80 exhst, SLP Lid

380 HP... doubtful. @ 350 is a good ballpark as 12 stated.
I am not a big fan of Fords anymore since my SVT blew up, but the '03 Cobras are pretty wicked - even Stock.
I wouldn't put any money down, or talk smack on a run with him until you get that Stall at least.
good luck.

A stock one will probably be a good race with you, I'd honestly give the edge to the 03 cobra. With at the very least intake/exhaust on the terminator it will beat you and that's probably the stockest cobra you'll find on the road.

Like lemons said get a converter. That cam in my opinion is alittle on the small side and not worth the money you spent. Next, you need to get a set of longtubes on the car. Watch the classifieds and see if you can't score a set of kooks or arh for a decent price. Did you port your stock tb? If not then you need to do that asap.

Another option when it comes to a good head that performs on a budget is the advanced induction stuff (AI--->).

Yes!!! You need to pick another cam. And you need new springs push rods timing chain and oil pump. Who is doing the install?

Answer these...
What rwhp are you shooting for?
What et are you shooting for?
Do you care how much the cam lopes at Idle?
Is it a DD? Weekend toy? How much track time and street time does it see?
What is your budget for your heads?
Anything else you expect the cam to do for you let me know.

You also need to let me know when the absolute soonest you can get a converter is. You can't go with a cam worth a damn without a converter. You will need a converter asap. I'm not going to tell you to get a 228r with a stock converter.... but chances are you would love that cam, from what I have seen you posting.. anything smaller and it isn't a waste of time but thy are very small cams.

Are the short headers installed already?
