    Gibson Headers and 6.5 Diamond Eye Diesel Exhaust on 454

    No clue about anything in the tune. I haven't spent any time in effort of understanding the parameters in the computer yet as I have the baststd 97 black box. I did assume MAF g/s regardless of how much fuel dials in against it, is just a raw measure of how much air is pumped through the...

    Gibson Headers and 6.5 Diamond Eye Diesel Exhaust on 454

    Long story short, last weekend my motor tanked on me and was losing all power at 3500rpm. Turned out to be a faulty crank position sensor that was new. Anyway, I have been watching the data stream and am curious where everyone sees their MAF g/s at under wot, I think I saw it at like 350. Its...

    Bummer, I don't see a 4inch in/out option. But damn they are long, would also prevent me from adding my cat converter

    Gibson Headers and 6.5 Diamond Eye Diesel Exhaust on 454

    Put the first miles on the exhaust last night. Was super fun driving home from my buddies shop to the house, was like driving my Vette but in truck form, super low throaty note, very loud under full throttle. Then put 50 miles on it towing 4k lbs boat, so it was just weight with no excessive...

    Gibson Headers and 6.5 Diamond Eye Diesel Exhaust on 454

    gibson headers, gibson y-pipe, are installed and cut as needed and plumbed into flowmaster y-collector. its insanity level loud with the flowmaster y-collector dumping right at the second level of seating under the trauck and without the rest of the exhaust attached, but that will get finished...

    7.4L Cam shaft options

    http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=589&sb=0 I just fired my engine last week with the above cam and its great. It is mannered much like stock with idle quality and vacuum. Passed AZ roller emissions with the factory exhaust as clean as a whistle. In all fairness i...

    Wow, pretty damn close in cam specs, thats wild... Really wish i ordered mine now in hind sight on the 110lsa. No issue at all in my setup pulling to 5k rpm, cam is setup with the Comp kit and measured during install so its all good on geometry and lash taken to 3/4 turn over zero. What are...

    What cam,valve-train are you running? I am running Comp XR264HR-13, 212/218 113lsa. This cam is so docile and well mannered it feels factory, the tune appears to have the idle right at about 700rpm, cam lope is absolutely minimal, lifters are adjusted at zero lash plus 3/4 turn, initially had...

    This truck is running. Broke it in with full factory exhaust, put 500 miles on her and have been working out odds and ends like brakes overhaul and a few other house keeping tasks. Cam and BlackBear tune with factory exhaust passed AZ emissions with flying colors. Exhaust to bolt up within...

    6.5 Diesel Exhaust on 454

    Not plumbed in yet. Motor build dragged on somewhat longer than i hoped for, however she has 500 miles on her now and the exhaust is up and coming in the next couple weeks. The Gibson headers have provision to attach factory EGR tube. I will however cap it off to avoid the heat transfer from...

    USCAR injector in L29

    Folks For anyone who has wondered if a USCAR style connection on a new injector will fit with the adapter under an L29 plenum, IT WILL NOT... Frankly the adapters did not want to even fully seat in the GM factory injector harness without being filed and drilled some inside the housing, so...

    Eventually I will likely have my tune transfered to a 411, but at this point I just don't have the motivation for the swap . Its brutally hot here in AZ so drive way work is very un appealing. I am however very interested in the tow/haul mode in the 411 and will eventually swap out. But in...

    1998 Tahoe Towing/Power question

    The larger the gear number the better it is for towing. Since you own it as a limited use vehicle you might be best served to research if that axle and carrier will take a 4.10 gear and have it changed. If its a 2 wheel drive platform it a fairly reasonable modification, if its 4x4 then thats...

    Towing rear sag question

    You have a fine dance there... Think about your Family and the Motoring Public... Look at your weight ratings for the rear axle on your drivers side door. Then load up truck with gas, all the crap that you will stuff in the rear and on the roof, add your Family or Friends that would travel...

    How does that 454HO 211/230 cam treat you on the street? I bet it treats you real good...!!! And Yes, the Vortec 8100 is King of the Universe...!!! In fact I almost went with that cam for my build, love that factory billet core on a 112 LSA with 4 degrees advance ground in. At the end of the...

    That truck is our tow pig, shags around a boat thats approx 4000lbs loaded on trailer or a toy hauler with RZR loaded inside thats approx 11000lbs. Engine started up one morning with some banging and my heart just sank. My gut told me a lifter had given up the ghost. I had thought well here...
