Speed Density Upper Intake different than MAF Upper?

MAC'n89Blckstng · Mar 3, 2004

My friend may be getting a new intake for his 87, and I was wondering if his upper and my upper are the same. Mine is spray bombed gloss black, I would like to try to polish my friends old upper and slap it on my car. I once put a upper intake on my car (Pro Comp plastic upper) that was made for Speed Density only (I didn't know this before I put it on my car) well, my car ran like total crap, sputtered at 500 rpm at idle. Would I be ok with the stock 87 upper and not have any problems?
Thanks guys,
Jesse

They are all the same, I've never heard of intakes being MAF specific.

Ya sputtered because the ProComp box upper is meant for SC applications...deffinately a big putting that on a N/A car.

BTW: Actually, the '86 upper and TB are both unique among the 5.0 HO's. The TB is 58mm instead of 60mm. And, the upper is more oriented for low-end and mid-range instead of the mid-range/high-end range than the 87-93 upper is oriented for. Also, '86's have flat top pistons and E6 heads.
