i've run 12.00 with cam only and 1.70 60' with a hot cam and long tubes

its mostly in the set up of the car susp., tires. etc.

 

damn, i must have some bad issues... I pulled a 1.7 60ft and 12.60 @108.. When I had my 95 camaro it went 1.8 60ft 12.80@107 with my set up without a electric water pump, injectors, had stock tb, lt4 hotcam, no port work, no stall, and the car wieghed 100lbs more.. Same exact motor just in a different car.. Im gonna take the heads off and have them checked out to make sure the flow equal, put a 3600 or 3800 stall in it and get a dyno tune or find a better mail in tune.. at least thats the plan..

 

damn, I can get stock headed LT1's running 11's. Somethings not running right on your car. And for one you need a way higher rpm stall

 

you need more converter. And what springs are you running..you really need to figure out why it stops pulling so low in the rpm range.

 

it'd be nice if you could post up a graph to see what's happening up top. one thing to consider is you may have valve float issues. i didn't see what valve springs you were running in that list?

i'd like to see a dyno graph of that too. my 211/219 was DONE by 6000rpm.

 

you are having problems that are holding you back. Before you go and spend more money on your setup you need to get the bugs worked out. Post a dyno graph and give as much information as you can. There are a lot of guys around here that know a thing or two, they can help you if you give the information needed. good luck

 

I had Comp Cams 987 double springs, good for .600 lift..

 

I don't get it... it looks like the test ended right at the problem rpm. I've never seen a curve like that just completely STOP dead in its tracks.
Was there any audible or visual hiccups or did the car buck on the dyno before the test was stopped? Looks like your A/F starts to spike right at the problem rpm... not enough info for me to add anything.
just took another look at the curves that are barely visable? are those yours? if so that looks like it could be a lean condition. did you get the valve springs new? what kind of 30lb injectors are you running? were they new when you got them?

 

I'm running some low 11's, still a hydraulic cam, just some LT1 Heads with a little work.

 

Times in sig are with a GM846 cam and ported stock heads at a 3680-3710 raceweight. Car didn't make much on the dyno but we all know dynos don't win races.

Other mods are slp shorties, 3.73s and a 3200 converter.

 

well one. you have a an lpe 74211 and i have a lpe 741216.. and your heads being ported would make the runners larger than mine making your cam that much smaller for your application than as my cam to would be to my heads...

 

Car didnt do anything unusal on the dyno, svo 30 lb injectors and springs were bought new.. I dont have a clue.. Anyone have some helpful info? The very light green line was on a 75 shot w/ nitrous works kit.. That got me a 11.80@116..

 

that makes ABSOLUTELY no sense whatsoever. do you have a dyno graph that shows power all the way up to 7000rpm? i would love to see it.
my heads were ported for the use of the 211 cam.

 

Thats all I have for a dyno graph... Would it maybe be taking timing out cause the knock sensor or something?

 

a scanner would tell you.
