I agree the stock heads are holding you back,but its not bad on the 60ft depending on what tires you have.I can see a 11.50 in your future with a decent set of heads.
race on.

Good thing you added the driver mod during the night lol. Seems pretty right for stock heads. Id say youd be looking at 11.5-11.9 with decent heads.

Nitto 555r's, I tried some different burn out amounts to try and lower it, but to no avail. Anywhere from no burn out, to john force burn out to the stage lights.

I am curious what is "wrong" or why the one person thinks something is wrong. Everyone else seems to think its about right.

If your referring to my comment don't take it personally. I said I wasn't bashing. Do like most and just ignore me, that's what I would do.LOL With a few more tweaks you should crack the high 11's. The only reason I would expect a little more and said so, is the fact that I have a friend with a stock bottom end, stock heads with a HotCam and all the other goodies that goes 12.30s at 112mph.

It ran 115 MPH on the STOCK heads. ET means nothing... its the MPH that indicates HP.

Hehe, no offense taken I was just curious. The day I get mad at someone on the internet is the day I find something to do outside.

Is this your first runs on the new engine?......the numbers look good, and when the heads and N20 get on there

Yeah, first time to the track with the new engine. Once we get heads, and some N2O flowing things should get very interesting. Plus a converter. Hoping the next time I go to the track to get some lower 60's when I lower my tire pressure 10psi or more. I believe they are at 26-28 now.

Not bad... people need to forget about the "383" in the sig and just consider it close to a cam only setup.

I'd say it's pretty good for stock heads an stock converter. A 3600 stall alone would drop that down to an 11.7 with approx. 1.6 60ft with some sticky tires. With stock heads the motor is going need some RPM's which he's not getting until further down the track. Some good heads and a good converter, this would be a low 11 second car easy. 115 mph sounds pretty good for what he has.

bombe, you definately need a 3600 yank converter with that cam. Im surprised your brakes even hold it. 115 is good for stock heads with that cam, and stock converter. Get the heads and a converter, your looking at 11.4s at least. I know what that cam can do, and your not even close to there :-p
