Happy 426 Day!
We’re wrapping up this conversion with our High Compression 426 Stroker Hemi V8.
Assembled in house, we start off with a 6.4 Block, machined to 4.100 bore and clearanced for the 4.050 stroke crank. Callies forged rods and Mahle Pistons along with a custom spec Max Effort Camshaft complete the shortblock. ARP hardware throughout ties it all together with a set of ported cylinder heads. A 3200 stall converter will keep drivability in check.
Final assembly in the next few days and then ready for tuning.
