My current engine setup in a '90 Mustang LX Hatchback is a stock blocked 331 cu in stroker motor. The upper and lower intake is a Holley Systemax paired with AFR 185cc heads, an AFM b-41 cam, and a Paxton Novi 2000 that puts out 10 psi. The car is a great street car that made 528 rwhp @ 5800 rpm. I would like to build a 347 stroker engine starting with a DART sportsman block. I am unsure of the rotating assembly I should go with. Also, what are my power potentials with the current H/C/I setup? My goals of 650-700 rwhp are going to require higher flowing heads, but what about the intake and camshaft? Ultimately I will be satisfied with a street car that offers more low and midrange power.
