  1. hey guys, i have an 88 with a 347 stroker, just put it in last wednesday, everything is fine except for this puk spot when throttle is at about 3 to 5%.
    Here is what i have under the hood: stroked 347, mass air conversion with bbk cold air, bbk 76mm mass air meter, 70mm t.b., 19lbs injectors, edelbrock performer intake, 1.6 svo roller rockers, ford racing e-cam, bbk h.p. fuel rails with regulator, off road h-pipe, but the thing is, the heads are a mystery. I do know that they are stock heads, but was told that they are fully ported with way bigger valves put in, and to say the honest truth, with this engine not even broken in, this thing is allready putting out some horsepower.
    Now as for the puk spot, is my car needing to be tuned, or does it sound like i have something going on?
