    the viper mistake

    Do those pw have a relay for them? My corvette has similar issues and it is because all of the voltage is ran through the switch adding resistance and connection issues, the easy fix is to add relays for the PW and just use the switch to trigger the relays. Oh and add a ground in each door...

    5.7 TBI Advice Needed

    Brain fart, i was thinking there was connection from the exhaust manifolds to that intake/egr that headers dont have. Join www.gearhead-efi.com and read, only thing you can do about idle air speed is to buy a cam less lopey. The idea behind lower rpms equals better mpg is very common and partly...

    Need TBI 350 build advice

    while ob2 isnt the best trying to the tbi system that is tbi requires modifying your ecm to use the larger chips or expensive hardware to burn expensive chips that may or not be wiped when you need to re burn them while tuning. He mentioned keeping the tbi system so its not carb swap to make it...

    5.7 TBI Advice Needed

    I didnt see anything about tuning the efi, that needs to be done for the new cam and remove the egr since you have headers. The check engine light on because of the egr adds fuel and pulls timing so you were wasting gas and no additional power. Also lopy cam creates slow air speed at low rpm and...

    Need TBI 350 build advice

    dont do it. stock heads are terrible along with the intake and cam, the engine is out of breath at 3k rpm. i did heads, cam ,intake on the one I had and then still needed to tune it, by the time you get it back you could ls swap it, with an od trans and be able to drive the interstate.

    Advice on freshening up a 350 tbi

    sell the 6.0 to fund the rebuild/swap. putting a stock replacement in there will be a disappointment. Something like this would be my choice since you dont want an ls https://blueprintengines.com/products/355-ci-crate-engine-small-block-gm-longblock-bp35513ct1

    Advice on freshening up a 350 tbi

    the stock tuning is barely adequate for a stock engine and it doesnt identify mods. the ability to tune is limited and a slow process. Stock heads, cam and intake are bad for performance you can mod it but youre better of ls swapping it.

    Advice on freshening up a 350 tbi

    In stock form yes the tbi is very limited, but making the fpr adjustable and a pump to support new pressure then you just need to tune it. I did all of these things and was working on tuning it when I sold it because I moved to Florida. You can use the tbi and an adapter to carb intake like I...

    411 PCM

    go here http://gearhead-efi.com/ pm lextech and ask him for the wiring schematic for your year engine. The l29 uses the same wiring pin out and bin file as the 01 vortec 350

    Advice on freshening up a 350 tbi

    the problems with vortec heads is they have no exhaust crossover and makes it a pita for cold start in the winter. They also use different bolt patter so any accessory that has a bracket connected to the intake may not work or require fab work. The stock heads, cam and intake are shit for...

    4l80e Speedometer Options

    you need both as the ecm has to be able to read the speed in 4lo or it rev till the engien blows in 1st thinking its to slow for 2nd gear. The 91 3/4 &1 ton truck had an electirc speedo try to find one or buy from ebay. Another option is find a convertor from the output of the ecm to a cable...

    Aftermarket ECM for TBI / SPEEDUINO

    Are you palnning to run e85 in the burban? If so you would be better off looking at the engine first, if it stock it is low compression and a terrible cam. Ive read the benefits of e85 comes with 11+:1 compression or forced induction engines and is why turbo guys like e85.

    Aftermarket ECM for TBI / SPEEDUINO

    Holley has been in the efi game longer than any aftermarket I think. They started way back when with the analog projection efi, then came the Commander 950 ( I just switched from one) then the HP/Dominator then sniper and now Terminator and Terminator X.

    Aftermarket ECM for TBI / SPEEDUINO

    We did this with an older Holley aftermarket ecm and innovate wbo2. The new hp and dominator systems can be set to us the sensor and add fuel as desired to the map.

    Aftermarket ECM for TBI / SPEEDUINO

    I know with the innovate wide band o2 it reads in lambda so it doesn't car what type of fuel you use. You could pair that with a Holley commander system that doesn't have a built in controller. I have one of these is sell. The other option is to get a Holley HP or dominator system.

    454 efi

    You want a single plane for efi. A dual plane will play hell with the fuel distribution and tuning. Call a cam manufacturer and get a recommended cam.

    Engine Question about Upcoming Build

    Use the 350 and contact local machine shops to see if they have some heads for sale that someone never came back for, Personally I wouldnt mess with anything stock other than the alum 113 heads, TPI heads if cheap enough, vortecs are going to cost you about $600 plus you will need a special...

    What to do with gas tank vent when all emissions components are deleted?

    if the truck is parked in a garage the vented gas cap may lead to the garage smelling like gas all the time not a problem with a detached garage but with an attached garage it can make the house smell like gas. Id prefer to reconnect the line and find a canister from one of the many people here...
