yo guys wutup, i'm dave chino and i got my 87 pioneer just afer this past christmas and started a resto/maybe extreme mod project. the day i got it a took intake, vavle cover, head, all exhaust, throttle body, and soaked anything that was gummed and cleaned all parts like new. i did a LITTLE port and polish to clean up the intake and ex ports for a smig of better flow. and put it all back together a few weeks ago. sounds great for 265K stock size exhaust with gutted cat and muff and i dumped pass side just inside front leaf mount. i found a little hesitation at 1st gas and drive and reverse are a little funny it takes around 3000 rpm to move eventhough 1st 2nd and 3rd work fine.4 wheel works great. needs ujoints and paint and floors and seats. butt it is a project truck. any ideas and functional suggestions would be appreciated
