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.
