So back to my first post, you should not have asked because you wont listen to any input anyway. You came here to have your ego stroked over a poor choice, not for infomation.

Typical kid, think you know more than the guys who have been there done that.
"bigger is better" is the oldest mistake in hotrodding, still alive and well.

Again I see one guy in this thread who actually used it, and used it sucessfully and even he is telling you not to, how thick do you have to be to ignore input like that???

 

typical kid thats funny. actually theres more then one person who has used that cam and he said he couldnt be happier with it. i made this thread to see what dyno/track numbers people are getting not for people to sway my decision on my cam choice.

 

I hope it works out for you! Let us know how it does. I'm always interested in how different combos perform.

 

ill keep everyone updated on how it runs. only 3 more months of snow

 

Haven't ran mine at the track yet, but it does drive and run good. No loss(noticeable) of low-end torque.

 

is yours in a stock short block?

 

Negative. But that doesn't affect the way it drives.

 

we shall see...hopefully some 11s slips will be in the near future

 

847 will be a good choice. i ran it on a 355 with lt4's made 399/387

 

with stock heads the gm847 will dyno around 325-335rwhp in a stalled auto or around 350-360rwhp with a t56

usually traps anywhere from 111-113mph

smaller cams that abuse the valvetrain less, drive better, and get better gas mileage with the same performance in a stock headed car are available though

 

Yup.

I'd say up to 115mph with a 6spd.

What smaller cam does around 360rwhp with stock heads?

 

well considering my (cc503) stalled auto(unlocked), 130k+ mile motor with midlengths and magnaflow catback dyno'd 325rwhp. I saw examples of gm847 dyno numbers (i.e. - saw one guy with lt's, 3" duals x pipe, stalled auto, newer motor) dyno only 10 more rwhp I figured if the cc503 dyno's around the same as a gm847 through a stalled why couldn't it replicate that through a t56

also there's a plethora of custom grinds out there that outperform off the shelf cams all day

 

I've yet to see it but I won't say it's impossible

considering your average full bolt on LS1 is good for mid 300's and traps usually 112-113 and a cammed 6 speed LT1 is good for around the same power then traps should be equivilent

 

Maybe a one-off, but certainly not common-place. 115 from a cam-only LT1 is very rare, with perhaps only a handful examples in the country.

 

It has worked out pretty well for me, but I'm not on a stock bottom end either. You need to shift at about 65-6600rpm if you run stock heads so it's too much for the stock rotating assembly to last very long.

Aside from that, it does pretty well. If you see my track time in sig with a 2.0 60', it would be somewhere like a 12.30 with a bit of traction which isn't too shabby. I raced a few cars supposedly making a lot more power then me and kept up with them just fine. I think the 6 speed + 4.10s combination makes it a very fast setup for what it is.

My gas mileage has been pretty bad.. 13-16mpg city driving and something around 22-24mpg highway.

 

Delsoto on CamaroZ28.com made 440rwhp and 400rwtq with a GM847.

 

Yeah I remember that. Do you remember what kind of heads he was running? I think it was either LE3 or AI 200ccs...

 

Im just missing 1mph to be at 115mph. Still got a few more mods to go, so Im confident it can probably go nearer 116mph once I get the intake ported and fix the ignition problem up top.

I used have a cam-only LT1 with a big stall and custom grind cam, and although this new camaro has a cc306 it feels way faster. Of course I think its just the difference between A4/3.73/4K stall vs M6/4.10's. My old car went 12.2@112mph with lots of problems, and this new car prolly wont do as good with the stock 10-bolt behind it. I blew my clutch the same night I went to the track so its been down for a while now.

 

Actually they are only the LE2s.

 

Aren't you at 3100 lb also? I think Frank went around 116+ at 3300 lb with the much smaller Crane 210/224.
