GP Pitts

I am thinking of buying the GP Pitts Special bipe, I already own a Quadra 35 engine. Now I know the Q35 is heavy, I know it is on the low end of the power requirement for this plane. But, is it enough engine to fly this plane and do scale like aerobatics? I had this engine on a scratch built 84" Laser

200 and it did just fine. A bit slow but could do all the cool stuff anyway. I got 8400 rpm out of a 18x8 Zinger wood prop. What da think? I can't even consider buying a ZDZ, BME, or DA engine at this time. TIA Tom Wales AMA 435536 The flyin' Saxman.
