i have a cam out of a 94 lightning block. My friend bought this block and put in a new cam. Well the one that he gave me is a roller cam. Not the flat tappet. What do I have in my possesion? It has the number 12 on the bottom and thats it. Also if someone knows the answer for the specs of the cam I would love it. I know its bigger than the stock HO 5.0l cam. I dunno what it is though. Any help?
1988 Mustang GT. Got my TFS heads and TFS stage 1 cam installed, now onto everything else.
If the cam is out of the 94 Lightning, and is indeed a roller, then someone did a cam swap.
Beginning in mid-production of the 93 year model, Ford went to a roller block, however, the Lightning remained a hydraulic flat-tappet cam, not a roller.
Hard to say without looking at the related hardware. If it used regular roller lifters like the mustangs, then it would be a regular roller. But, if it used longer roller lifters, it is a conversion. The conversion used a small base circle cam because most blocks are not roller and do not have the extra support near the top of the lifters.
