new user....probs with '86 stang

hey, i just built me a little stang. its an '86 notch lx 2.3 4-speed originally. i dropped in a semi-built 351W with a t-5 and 8.8 out of an '87 turbocoupe. now, the problem is, when i get about half way into my trottle, it starts vibrating really bad, but smooths out somewhat up top. could this be an unbalanced driveshaft? i'd appreciate help.

Stop driving the car. The 351W requires 28 oz. balancer and flywheel/flexplate. The stock '83-'95 5.0L flywheels are 50 oz.. Get the correct flywheel before you make things worse.

i'm sorry, this is a little new to me. can you not balance a stock flywheel to make it work? can i change out the balance weight with a 28oz weight? if not, where is the cheapest place to get a new/used flywheel?
