Sled Head Racing (Big John) 840 HO big bore
- porting
- 14.7:1 RKT head
- newer style pistons (NOT Weiscos)
- freshly built top end 11/2008
Its not an RKT big bore, but the pistons are the same manufacturer that RKT uses. But being a different bore, they are to Big Johns specs. Cylinders were recoated by Big John or whoever he uses. Big John did all of the work on the engine.
Was in a 2005 Summit X. Had it out west over Christmas and ran great!
asking $3500 NOW $3000 Lowered to $2500
