fueling is definately important like rich was saying the stall could knock off .4-.5 and Id think another .4-.5 with a complimentary cam like something in the 228/232 duration and .58x lift that cam is small for a 6.0 NA application, youve allready got the heads that flow great for it.

Another thing to ponder while

 

I hear you about the cam, that is being pondered also. I am going to talk to Allen and see what we can get figured out. I just have to get him some data. I am going to get after it today.
I am going to see about another cam, then ditch the 1.8 rockers so I can try another lobe. I have a feeling that this low lift Comp cam is leaving alittle on the table.

 

I forgot to include exhaust aftermarket cams dont like back pressure, I found this out when I did my cam and some headwork first and couldnt figure out why it didnt make an enormous difference, then I redid the y pipe got rid of the cats, lt's and a cutout that made a huge difference

 

Well With The 1.8 Rockers His Cam Is Around 218/222 To 220/224.don't Think Cam Is To Small Just Put Vertter In It And Some Tunning Could Pick Up Alot.

 

Sounds like the cam, head, and rocker combo is pretty well matched IMO, if you could get the tune just right and get a mild converter (2600-2800), I'd think you should definitely see the 13's you're looking for. Man you're so close you can taste it huh! Sorry Tom and I couldn't make it down last night, glad to hear that you picked up a tad though...wonder if you could tune another tenth off it and get a verter to squeeze your 60' times a bit.

 

Yeah, I can taste the 13s. I quess a stall is in order. I going to try to tweak the tune alittle this week with Allen's help. I have 2 more chances to go Wed. and Fri. So I will try to get the tune alittle better than do some other mods over the winter. Its not anyone fault, just new parts have to be tuned in. I am sure Allen is close, It just needs to be tweaked.

Bud, hows the shoulder? Man you missed some cool things last nite. I pulled into the staging lanes and there is a brand new 06 z06 rite next to me. This is the first LS7 I have seen. It went 11.6X at 123 mph, rumor was it was bone stock. Badass!

 

Sounds cool, sorry I missed it. I'm still hurting pretty good, but the doc just put me on a new med to try and speed up the process...it's taking a bit longer than I would have hoped. I'm gettin fat and spending waaayyy too much time on the internet lol!

 

Good to see you are getting better, Looks like I am going to try to make some changes and go back this week. The truck feels real good , just doesn't have any go. I am just alittle puzzled rite now.

 

Matt, any update on your truck?

 

Well I am running out of injector on the top, this is causing some of the problem. I talked with Bryan at PCM for less, He has a heads and cam SS also, he ran into the samething on his truck. Allen's tune is real close, it just needs to be tweaked. Nothing against Allen he has been a great help to me over the last year or so, I think I have just out grown a mail order tune. I am going to get 42lb injectors and it is going up to Bryan's to get dynotuned. He is booked until after Thanksgiving, so it will be a few weeks til we see the numbers. It most likely won't make it back to the track this year, unless I can make it to Atco or Island. Not sure when they close. I quess dyno numbers are as good as a time for the winter, I might make some big changes over the winter anyway.
