I gotten a 12.24 with only pulleys, HppIII, 100 tnt n2o, And some e.t streets at 4500 da up here in Idalou Texas. That was my best. As I recall it was a 12.24@115 mph 1.89 60' time

 

For a street car I believe that I have one of the faster ones. I've run 11.40 116.59 with a 1.47 shortime with stockheads na. I run the Crane 210/224 cam and my car weights 3327. And to my knowledge Frank W. never ran a 11 with stockheads. I have a stock suspension with swaybars removed and a airbag in the right rear spring. Frank95z

 

I am not trying to be a smartass. You can take it how you want. I was saying that i believe we all know you have to hook it to run good times. Don't we all agree on that? I am not disagreeing with anyone, i am saying i just want to know the cams people are using.

Thanks guys that actually posted about cams you are using to run 11's.

 

I found all of the info posted here to really helpful. Gives me hope for the hotcam I just bought.

 

White Knight - you are going to need ~350 - 360 rwhp to run 11s, if you hook, and don't break (like mine did :-(), in a roughly 3500lb car. With that said, the CC306, GM847, 233/239, and similar all seem to make in that same ballpark. Some might peak a little earlier or later, but in general, they will get you where you want with stock heads. I'm please with the power my car makes, only change I might do is an electric waterpump, to see if I can hit 365. Soon as I get a new rear in the car, back to the track it goes with the ignition and see if I can crack the 11s. I know the car has it, its just a matter of getting it to do it.

 

Since your running on stock heads, wouldnt see that much a benefit running a massive cam, big cam wont help out till you get heads on the car.

 

With what you have for converter, gear and mods....

I would look at a LE2, 306 range cam. Things like the 306 and 87 are nice but they have too much LSA. You might be able to do go to something like a LE1 cam and get where you want to go.

As for the rest of the combo....

Stock Lifters, Beehive Springs and 1.6:1 Pro Mags with some good pushrods.

Your looking for the most average power from 3200-6500rpm.

The rest of the setup and weight is really the key here, a car with a trap of 109-112 can get in the 11's, 350-360rwhp @ 3500lbs is more than enough to get you there.

stock lifters? Most guys here would say Comp cam R lifter, right? It seems most are using them. Why stock lifters?

 

Bret mentioned beehives as well - I think (which can get me in trouble sometimes) that's the reason for his suggesting stockers.

 

Beehives. You put less pressure on the stock lifter with a beehive vs. a 977 or K800 or whatever.

Comp R's are EXTREMEMLY good lifters when you want to put a lot of pressure on them, the 26918's on a LT1 don't put as much pressure on them so you can get away with it. This is about the limit on the stock lifter.

You beat me!

Nice Combo BTW "APE 355, LE2 heads/cam/intake, & 3000k stall awaiting lazy *** to install." a 3000stall and the LE2 cam work really well together!

Bret

 

Thanks! You actually helped me and Lloyd a while back with the beehive combo I have on these heads (dunno if you remember, I know you help lots of us out).

I need to get this thing together and see what it does...

 

Thanks guys that's the kindof info i needed. This second page of posts is helped a lot.


Yea i'm going to want the power up above 3200. If i don't figure something out, I might just call Comp Cams and see what they suggest. It doesn't hurt to see what they say.

Do you guys know where can i get these behivee springs and how much lift are they good to? I will probably go with new comp R lifters....would the behivees work good with them also? Or should i go up to something else since i will have the comp r's? Is the LE2 cam like the CC306? It's just i haven't ever heard any specs on the LE2, so I didn't really think to run it with stock heads. It might be a good choice. Right now i'm thinking the 306, but if the LE2 will work good with stock heads i might go with that.

The thing is though i want to spray on top of this cam once in a while 125 shot--maybe less (don't have a roll bar...so will have to keep it at 11.5) having a tighter lsa would help on the nitrous side, but with the size of the shot i doubt it would really matter. I don't think it would hurt if i ran a 112 lsa cam would it? I will mostly just run N/A on the street and just use spray some at the track, so i really don't want to give up too much power N/A. Does anyone know of someone spraying on something like the CC306?

Here is what i have right now (in my room ready to install this summer):

1.6 Magnum rockers
Comp R lifters
comp Chromoly pushrods
electric water-pump

I am just stuck on the springs and cam.......

 

Comp R's and Beehives are fine. I just like the Beehives for many reasons and they work great with Comp R's.

IMHO people over LSA N2O cams. In general they are actually pretty dam close to NA cams just with more exhaust duration. I have done some N2O cams with a high LSA but also a high duration and small cubes so it's all realtive.

Actually a LE2 is a good N2O cam for a small N2O shot. That's not just pumping it up either. There's not enough overlap there to make the LSA higher so it will still work on a small shot without any issues at all.

interesting.....maybe i'll have to talk to Lloyd about this and ask him if he could set something up for me. Do you know where i can get these beehive springs and the spring rates? Do they fit stock seats or do they need machined?
