    It's one of those "I think I feel a difference" but it's not substantial enough to have the seat-of-the-pants improvement. The 2600 stall isn't cutting it. I guess the powerband of the 224 cam is too high to be a good match for the converter. My 60' times are going to SUCK.

    Do you get a free restall with the Yank convertor that you already have?

    Installing the alt pulley may take HP away from the engine since it will be spinning the alt faster. It will restore voltage back to the battery, the biggest gain you'll probably get from it.

    Always put a new bolt in the crank every time. They are not reusable and may break during a second installation. I think they'll about $4.00 at the dealership and will save you much headache if you strip or break one, or have a pulley come loose or off. They are a stretch to yeild type bolts just like the head bolts and I have a sneaking suspicion that you would not reuse the head bolts...

    I don't believe Yank gives restalls.

    I'm not having any issues so I may just leave the alternator pulley off.

    Good info on the crank bolt....didn't know all of that.

    Thanks, Greg!

    Yes you did Moze and you witnessed it happening first hand when i broke the bolt in the 5.3, that&#39;s why i was telling you to get the new bolt, but you will be okay with the one we used

    I knew that it was better to get a new one, I didn&#39;t know the specifics as far as (quoting Greg): "They are a stretch to yeild type bolts...".

    Moze, it was a new one. We always use a new bolt if the old one has to come out.
    I think the bigger stall will help you out alot; not as much as a 2wd rc though.

    Oh, I knew you guys used a new one - I bought it and left it in the truck for you&#33; This was the first time removing it, so I figured it would be fine. Guess not. Maybe I&#39;ll give Art Carr&#39;s converters a try...also looking at Edge. They seem to be making a good rep for themselves.

    I just went out to look at my truck. I was wondering why we just couldn&#39;t put on a bigger water pump pully. Now I know, no room for a bigger wheel&#33;&#33;


    I thought I was on to something.
