MS4 cam and supporting mods...what shoud it run? Recently did the heads and cam swap in my 02 ss camaro.Installed the Ms4 cam,stage 1 prc ported Ls6 heads from texas speed,4000 stall,lt headers,ory and a lid. Car was dyno-tuned by Speed inc.Made 406.7 hp at 6300rpm.
Ran it a couple weeks ago...12.1 at 111 mph. Not the e.t. I was looking for,expected to be in the high 11's at least,but that time was run on the stock 3.23 gear.
This past week a put in a set of 4.10's and had the speedo and shift points re-calibrated. Going to run it one last time tomorrow. It's supposed to be in the high 50's up here in northern Illinois.
What time should I expect to see?
Forgot to mention, MT ET Streets at 15psi. in the rear.

60 ft was 1.75. convertor is a 4000 vigalante. Haven't weighed the car, but it's safe to say that it is close to stock factory weight.No weight reductions have been attempted. I do agree,the trap speed is way too low for what I've done.

[QUOTE=blwn_00gt;14087136]i ran a 11.40@117 with a 224/230 cam, long tubes, 3200 vig, tuned, with 3.23 gears and stock 241 heads. only weight reduction was big and littles...[/QUOTe
Thanks for the reply. Everybody I talked to said the 3.23 was what was killing my e.t's and trap speed's with the ms4.From what I gathered the ms4 needs atleast a 3.73 in a A4 to come alive.
Maybe I should've went with a smaller cam on my stock 346 LS1.

stock tranny is ur problem, you cant spin a stock tranny over like 6200....i had mine shifting at 6200 (just barly bumped up from stock) and was bleeding off line pressure from the weak pump slide spring and was burning up my 3rd gear clutch pack...when i got my tranny built they put the z pac in it and all the good stuff adn now it shifts perfect at 6300....id bet your 3rd gear clutches are fried and you need a good transmission since ur probly shifting that thing at like 6900....hell no dont kick urself for going to big just get the bugs worked out and run tens like ur suposed to !

Was on phone before, I can give a more detailed response now.
The thing about the "donkey dick" cams.. Everyone wants to get them but does not want to sacrifice driveability or the spend the money on good flowing parts.
For instance... They don't want 410s/4400 converter/good flowing heads/FAST/etc etc etc..
The big cams are good cams you just have to compliment them with the right parts, which in a DD, is sometimes a pain.
The 410s will definitely wake it up.. However, it should be KILLING anything.
You can't just go off mine and other peoples times... That is NO indication of what you should be running (only knowing that small amount of information).
First off, what kind of DA are you running in?
Mine was in 2000+ (give or take a few).. My car was quite a bit liter than yours though and I had a FAST intake. Makes a difference..
I doubt it is the launch.. Just play with it some, leave at idle/leave at 1100 RPMS/leave at 2500 RPMS/leave right before the tires start to break. ALL cars like leaving different.
I had 115K+ miles on my car with a 4000-4400 converter/410s/H/C/full bolt ons/etc etc and cut 1.5 60' cam only and 1.6 H/C spinning... Shifting at 6200 cam only and around 6350-6400 H/C. Never had a problem.
Of course though, a built trans won't hurt anything!

Results with the 4.10....11.85 at 115 mph with a 1.65 60ft. Still think I'm leaving some on the table, but time to put it away for the winter and fine tune it.
Not sure what the D.A. is at Byron dragway.I'm sure it's not that much above sea-level.
Thanks again to everybody for your input and advise.
