    Inline fuel pump vs tank fuel pump

    Unless you have some kind of baffle structure in the tank, get used to keeping the tank above half full or the engine will stall when the pickup is uncovered when you go around corners. I've got the Walbro 255 externally mounted under the passenger seat right now, with a cobbled up factory...

    5.7L Ignition Timing Table - Feedback

    Honestly, my spark table looks kinda like the one in the OP. Past about 2000rpm, it's really hard to get the engine to spend much time between 90kpa and 50kpa, so I sort of get the top two rows tuned for WOT, and never really got around to modding the middle of the map. This might be why the...

    5.7L Ignition Timing Table - Feedback

    Some people call it a "spark hook test". It's a series of runs (with cool down in between), where the advance is started low, and increased a couple of degrees each successive pull. On most engines with decent chamber design & quench, power will stop increasing at some point, slowly decrease...

    Engine Masters - X vs H vs Straight Exhaust

    The whole point that everyone is missing is that X pipes drop ~3dB. X-pipes make more power because you can use a free-er flowing muffler that would otherwise be twice as loud. Also the formulas for best H vs X pipe placement are different. Once the ideal collector length is established, the...

    5.7L Ignition Timing Table - Feedback

    Don't know specifically what numbers should be in there, but some things to keep in mind: 1. Modern engines with great squish and multiport EFI (especially dual plug!) have very efficient and fast burning heads. Mid 20's can be A LOT of timing, especially around peak TQ. 2. As you turn up...

    What a RIP OFF!!!

    The water in the pre-mix isn't tap water or distilled. It's fully de-ionized so that it doesn't create any corrosion issues.

    How to remove a rusted/frozen radiator hose barb

    Start by sawing it lengthwise as far down as you can go. Bust off half with a chisel. This one's almost off. The other side is next. Take the blade out of the saw frame, and cut parallel trenches in the fitting. Pay close attention so you don't cut into the manifold threads - you...

    Why doesn't my billet front drum fit?

    Thanks folks. I talked to Paul from TCS, and got the low down. There are two widths of front drums and their associated bushings. All billet drums made are 72+ late type, because that's what essentially everyone is using or have upgraded to. I just need to find a 72+ stator tube (what bolts...

    Kickdown lever

    I had to drill mine out until I could finally rip the threaded shell out with an EZ Out. I tried using a socket extension, and that basically reamed the plug into a nice round hole.......

    Why doesn't my billet front drum fit?

    So I bought the hot-****, half-a-mortgage-payment, billet front drum from TCS. http://www.tcsproducts.com/products/product/tf727-steel-front-drum-aluminum-piston/ Now my transmission won't go back together cause the pump body is bottoming out on the drum, even without any thrust washers at...

    Anyone use a Keisler Transmission ?

    I figure next step is pulling the trans, and see if something's messed up with the converter.

    Anyone use a Keisler Transmission ?

    Yep it's like the converter is locked 100% of the time. The day I got it all installed and plumbed, I fired it up. At idle, and the foot on the brake, I ran it through the PRNDL, to fill all the circuits, and it worked fine. Only problem was a drip at the fitting between a braided cooler...

    Anyone use a Keisler Transmission ?

    I wish I never saw a Kiesler 4L65. I am thinking seriously about pulling it, smashing it to little pieces with a sledgehammer, and putting a 727 back in. I have about $8000 into the whole Kiesler project, and nothing to show for it. From the start it's been an adventure in bad info, delays...

    (SOLD. Thanks Garner22! A+) smallblock pattern 727 with ~3,000 miles since complete performance rebuild - removed from Abody in fine working condition for an overdrive swap. Drove to The Nats and a couple legs of Power Tour without issue. All new bushings, bearings, seals, raybestos...

    Efi

    I use a older Holley Commander 950 TBI set up, with the wideband upgrade. The change to the car's personality was about as extreme as adding the stroker motor. There is a $15 software hack out there to make it self tuning. With a little snipping and a couple (gasp) GM truck parts, you can...

    Turbo 440 Dodge Truck

    The intake is awesome. It is basically a sheet metal tunnel ram, scaled down slightly for street use, and cast in aluminum instead of tig'd. More TQ and HP everywhere. EAPro simulations absolutely loved this intake. It was a Gen 1 ProFlo kit from several years ago, that was on clearance...

    I don't think it was a sprag failure, because neither the overrunning clutch nor the front drum seem to have blown up. appears to be mainly a bellhousing failure. Since the crank is spinning CCW from the rear, I'm trying to picture how something could have jammed so that the reaction force...

    Turbo 440 Dodge Truck

    It ran 14.0s NA with the RV motor with ported smog heads & cam. It ran 13.50's with the Eddy proflo. It was getting into 12's on 150 nitrous shots. (it has 3.91 gears, and was severely rpm limited once power adders started coming into play. It was bouncing off the rev limiter far short of...

    Turbo 440 Dodge Truck

    Had some requests for pics of my friends truck. Eddy ProFlo MPFI intake, big turbo about the size of a 15L diesel turbo, old RV 440 in an ex forestry service truck. Ported smog heads and an old Purple shaft cam. The OEM grill was replaced by an enormous intercooler liberated from some on...

    His ignition woes were mainly the result of Eddy's backwards pig latin software and their insistance on a one of a kind distributor. Eddy's tuning software is seriously the most convoluted illogical mess I've ever experienced. It made my old Holley commander 950 look like HookedOnPhonics...

    anyone put a 4L60 in an Abody?

    I'm installing the Kiesler kit into a Duster. I followed the instructions for boxing the factory crossmember, but when I tried to put the trans in I'm about 1/2" of interference. Anyone else have this problem? The trans is coming out for the 3rd time to make more room. The boxing was a...

    nope it didn't blow up on the shift. It was topping out in third gear, and he was just about to get out of it and shut it down. It let go roughly 5000rpm. on the plus side, the AFR was right and intake air temp was pretty good. The truck has the Eddy ProFlo MPFI set up, driven by...

    riding shotgun when 440 BB Dodge truck at 12psi WOT blew up last night at the top of third gear. Not a stutter or hickup until it let go with BANG!! followed by a comet tail of sparks, and clang-a-langing. The explosion rocked the truck, flattened the rear right tire, and hit the passenger...

    Beehive valvesprings on all roller 408 smallblock

    ps - the fan belt problem was fixed in many cases by slitting a section of radiator hose, and sliding it over the coils. the rubber absorbed enough energy to keep the spring from resonating, similar to the metal damper in valve springs.

    Beehive valvesprings on all roller 408 smallblock

    Thanks Moper, that's the best explanation I've ever heard. I saw something like that at a diesel engine OEM once, but I understand it alot better now. There was a spring pulling the fan belts tight. Turns out, it's natural frequency happened to be the same as the engine at high idle. You...

    Beehive valvesprings on all roller 408 smallblock

    FWIW, I shift at 5,500. I forget where I heard it, but the worst spring surge supposedly happens far below red line, and that's why they put dampers and such in there. I think it's a slightly different issue than valve float, and can cause broken stuff from fatigue. but I digress. I mainly...
