OK here it goes....this is simply my opinion based on my experiences, and only to give Beech some more info. I've raced a bone stock motor(bolt ons and nitrous) two full seasons, with 105 passes. Half of those passes were 11.0?. Finally cracked a piston. Next was a full built motor(rods, forged pistons, stage 1 heads, balanced, etc, etc, with s475, 60 overs, and nitrous) approx $10,000 involved. This motor made four passes on spray, and four passes on motor(half of these were 1/8 mi). Best pass of 10.71 1/4 mi, and 6.59 1/8 mi. It melted a hole through one piston and the other seven were heavily deteriorated. Next motor was "play time". 85,000 mi, bone stock junker........with the s475 and nitrous.
Four, low 11, 1/4 mi, motor only passes. Three, 6.60, 1/8 mi, with spray(Schied event) Last pass bent every rod in her, and grenaded the track.
Current motor, like Trent said, is a stock motor with a rod swap. I pulled the stockers, put in my rods, my stage one heads(fresh off the blown up built motor), studs, my s475, and the spray.(no machine work, no keys, no torque plate, no hone) 10 passes so far, all on nitrous. Half are 1/4 mi, with a 10.24 best so far. Half are 1/8 mi, with a 6.62 best. Still running strong. Just waiting for better weather, or the Bradenton race, whichever comes first:thumb: Beech, take this for what its worth. I hope it helps.
