    Which wideband to buy?

    It just toggles rich to lean, like the stock O2 does at above or below stoich.. Instead of using something in the range of .5v, like the stock one does, the WB crosses stoich, at ~2.5v. And, the 2.5 can vary a fair amount depending on how the manufactuer sets things up..

    Edelbrock IAS

    I tried them, and then went to the Bilsteins. While they (the IAS) offer a slightly better turn in, due to their firmness, overall handling, and ride suffered, IMO.

    strange question on brake lines

    Are you talking about from the M/C to the combo valve?. The body is mounted on bushings to the frame, so there needs to be some *slop* in the *system*. If they were mounted *hard*, they'd work harden, fatique and break.

    Roller vs. Tappet....again!

    I'd go with a bigger roller cam... They're just so much easier on the other valvetrain parts. While they can support a higher valve accleration rate, I wonder if as small as what we're talking about here, if it's even applicable. 60 PPH's, I'd be watching the Duty Cycles, even with alky...

    Help!!!!! Takes too long to fire

    There are two parts to the ignition module. One is during low RPM crank, it operates independently of the ecm. Then as RPM build, the ecm takes control of the timing (still during crank). *If* the low rpm part of the module fails, then the engine has to crank long enough to hit ~400 rpm for...

    Increasing plug gap fixed my issues!

    Just forget I said anything. Now you're starting to cross talk the conversation.

    what size spacer to use? 89-96 vette wheels

    Skulte Design says 2", as I recall, thou, with my setup I think I wound up with 1 3/4, and 2"s.. I have/had the ZR1 lookalikes. Andre had a *free* return policy at one time, so you could really make sure you had things correct before being locked into the sale, but you had to keep the...

    Engine Assembly Questions

    Check out what you said here: Drop in pushrod and install rocker arms, adjust the rockers to no threads sticking out of the bottom then adjust the pushrod to snug and then measure? My response was telling you to rethink, and redo your entire procedure. *If* you were to just do what you...

    Cranks...No Start..After Inj.Chng

    Reseat the chip, after looking to make sure all the pins are right. No communication, is not a good thing. No ALDL, can mean the ecm is using the RFD, redundant fuel devise, and that'll foul the plugs quickly. Using the RFD is truely being in Limp Home Mode. LMM is when the processor is...

    Increasing plug gap fixed my issues!

    As I said, his is but one view!. Pre-ignition can very. It's not always an instant kiss of death. Not to mention you can have both occuring at the same time. Again, a K/S is looking for a particular range of sounds, and a given volume. *You* can add enough fuel to alter the acoustic...

    Increasing plug gap fixed my issues!

    It's completely different! !.... While detonation can at times lead to pre-ignition, pre-ignition, *CAN* be more damaging then detonation. Both are abnormal combustion events. While some like to lump the two together they're not the *same thing* Here's a short text about them. There...

    Engine Assembly Questions

    BE SURE YOU CAN MOVE THE PLUNGER (within the lifter body) WHEN YOU'RE DONE! !!. The shipping goo in there can turn about solid, and at times won't wash out easily. Tap lightly, and go in small tor steps. Yes, 4x the end play when done. Instructions on cam should tell about what to do for...

    new alky kits fors gn's!

    After playing around with putting my own together, and modifing another one, I saw that they could work.... Then I meet Razor at the Nats, and after talking/ seeing him in action, the *thinking about it* was over. He knew his kit, his car ran the numbers, and I was in a car pre and post...

    Cranks...No Start..After Inj.Chng

    Dribble enough gas into the motor to foul the plugs?. If you have a noid light blinking that means, you have at least ignition pulses reaching the ecm. Which means the ecm is trying to fire the injectors, and there are signals going to the ignition module. Fuses and fusible links.. But...
