You're confusing yourself, and the issue. Does your engine run badly? Fix it. Don't complicate it by trying to hide one problem with another. Why did you put a stroker in if it you can't make it run right? Put a STOCK engine in, and get back to driving. It's cheaper, easier, more reliable, and more useable. A stroker is worthless if it doesn't run better than stock, and it sounds like yours DOESN'T.
There's nothing special about a '92, and anything that can be done to a '93 can be done to yours. Wherever you're getting all this misinformation, STOP GOING THERE. The trans has NOTHING TO DO with how the engine runs; it doesn't care if the engine is MAP, MAF, or a turboshaft. So stop worrying about it. If you have an EEC that will control the engine you have, and the trans you have, you're done. You don't have to fret over what kind of engine the trans was originally running with.
But if you can't personally do a MAF swap, then you certainly don't need to pay someone else to do it for you, making you permanently dependent on him to maintain it. A stock engine will run better, make more power & torque, and give better MPG than a stroker that doesn't run right. It'll also LAST LONGER...
...and cost less to maintain & operate. Do you want to spend all your money & time ferrying your truck to & from a shop so that you can say "I have a stroker!
", or would you rather spend it ENJOYING driving the truck?
