    Good find. Of course you don't have to buy the tool GM uses. I use the tapered plastic tip from a gasket sealant. I cut off the tip that is used to expand the seal onto the injector. I make sure it...

    Yep. The seal has to get back down to size or it will be damaged on installation. Initially you will hear a light ticking sound but as the seal burns you lose compression and exhaust out around the...

    Since the number don't really add up or divide or.....Maybe it would be possible to just try .72....71.....70....etc and watch the results?

    Two cam related thoughts:
    1. Lots of cams run a smaller base circle than your original. Even an original LS6 cam uses a smaller base circle requiring a longer push-rod or the changed geometry that...

    The way I understand it, from 2017 up we cannot read GM TCMs, at least the T87A. When hooked up to the internet....we end up getting a trans file BASED on the TCM that is seen....but it is not...

    I don't think so. The ISS version of the 4L60E was not introduced until GEN4. Where GEN3 uses engine RPM for input speed (and has no way to know for sure if the converter is slipping or a clutch...),...

    A reduction in knock retard right when you hit the gas, due to getting the right amount of gas right when you hit it, is quite noticeable. On older V6 P04, tuning VE had questionable value because it...

    Simply put, when you hit the gas the MAF won't even find out it happened for a while. The MAF is down around the corner. However, the MAP is right there in the manifold and it knows the very moment...

    Which GEN? With GEN5 PCM gets BCM speed limit via GMLAN. If you don't want the BCM's opinion, just go to Speedo>Limiter>General>Source>GMLAN and...

    You really need the VVE right on in order to make accurate transitions. The MAP finds out that you opened the door (throttle) WAY sooner than the MAF. And a colder motor is much more likely to...

    My old 68 C10 weighed 3660, not too portly by today's standards.

    T56 is on his list.

    1/16" off the heads is a lot. Small base circle cam probably...maybe stock length pushrods are not too far...

    Recently I used a 2002 Corvette 0411 (obviously V8:) on a friend's Mini 4.3 swap. It worked flawlessly. I just used GM tools with ACDelcoTDS to change the system to a manual trans 2002 4.3 5speed....

    You are right. Even a fresh 2019 L86 runs noticeably smoother after the crank position is learned. It is worth it to find a 2003 V8 P59. I don't know all of the differences between 2002 and 2003 but...

    There is certainly no need to go from an 03 back to an 02. The 03 has a few advantages and yes, the 03 P59 is for both V6 and V8. My Tahoe has a P59. I am just not totally sure that a segment swap...
