Goon it is mine and it is for sale! It ONLY has the 100" HiPo S&S mill, but she is crazy fast up to around 80 - 90 mph and the torque is incredible. The 100" engine is my favorite out of all the first generation Feds, they came with: S&S 98, 100, 113 a couple of the last ones had 124 / TP 107 / two versions of the Merch 120 not to mention a few Mid USA 124 mills.
My buddies 2nd generation Hellcat had the 124 or 128" Confederate designed engine with some super nascar technology? Claimed around 150 ponies but in reality was only 115 with exhaust through the swing arm.
