It's very easy... a SBF built to Dirt Late Model spec starts at $42K... SBC $38.5K. Built to off road truck spec is $48K.
These are open competition motors, meaning no rules or restictions other than single 4 barrel carb... any cid (BB or SB), any head, crank, rod (Titanium), compression, etc. Though BB are allowed, none exist in this form of racing. All are SBF or SBC, typically displacing 430 cid while weighing 360 lbs. These are the engines that drive the development of the SBF and SBC.
