2.85L Hybrid Stroker Engine Build

I love the idea of developing reliable, large displacement motors at a reasonable cost.  This build is based on a design developed by Sid McMullen. The motor will be used mostly for street use with occasional track days. I had some very high goals for the build:

- 400 rwhp/400 ftlbs torque at 6200rpm
- Near k26/6 bottom end performance
- Total cost under $4200 for everything, including my "High Flow" head

- Using 86 Block, dry sleeved, bored to just over 102mm, half filled
- JE Small Block Chevy Pistons, Forged 4032
- Eagle 150mm Mitsubishi Rods
- 86 2.5L crank, offset grind, 86mm stroke, cross drilled
- Compression Ratio is 8.1:1
- ARP Head Studs
- Cometic MLS Head Gasket
- ACL Race Rod Bearings
- Crank Scrapper
- Stock Cam
- MoCal 13 Row Additional Oil Cooler, 235 mm
