my buddys got a like new MSD box for sale. sold the truck and kept it. think i can get it pretty cheap, wondering if its worth it to put on my 89k5. if not... i also have an older pickup with a 70's HEI ignition. should i buy it and what should i put it in? he noticed a difference in his 95 V6 S-10. a little peppier@ midthrottle. my truck is lagging in that department.
