Would MSD ignition help on a Vortec engine?

    In a few hours I'm purchasing a 96 Black Tahoe with a Vortec engine. I will be putting my truck up for sale and I was wondering if I should take the MSD box off of it and put it on my Tahoe. Would it make a difference on the Vortec engine?

    If it will help, I may pull the MSD spark plug wires off the truck, put new ends on them and put them in the Tahoe. I would then get a generic set and put on the truck. I still have all of the old HEI stuff I could put back on the truck but before I swap, I want to make sure there will be a noticable performance increase.

    If you have any experience with an MSD and a Vortec motor, please let me know.

    Thanks.

    If you already have a good HEI system I don't think you will see any big performance gain putting in an MSD on a stock engine, the HEI is a pretty good system in it's stock form.

    I'm with bajaviking. The difference you will see from (assuming) carbed to injection alone will render the better startup/idle issues null, and HEI is unbeatable for typical use.

    There is no power gain from the ignition boxes, (or not enough to worry about) so in my thinking, the injection alone will render the MSD worthless.

    I agree with the arguments set here, but if it were me, I would still pull the MSD and related parts, and sell them seperate for some extra cash /forums/images/graemlins/thumb.gif

    Sounds good guys. The MSD helps on the old chevy but I wasn't sure it would help on the Vortec with the newer ignition systems. You probably saved me some dissapointment.

    Thanks.

    I have one on my 97 k1500. I have not noticed a difference. It looks nice under the hood.
