I just ordered a 347 stroker, the pistons are made for the twisted wedge heads that i got. I have the E303 cam, but i was wanting something bigger, little more aggresive. this is what i have so far gt40 u/l intake, track heat heads w/ 1.6 rr, 24lb injectors w/70 mm maf, 65 mm t-body and spacer, CAI, long tube headers, custom made x pipe, slp loudmouth mufflers, 3.73 gears, t-56 trans, u/l control arms, and now a 347 stroker kit on its way. should be at my house next week. i have to find a good cam for this set up, thanx
