Darton-Sleeved N/A 434"

We started with a factory Gen IV aluminum block and carved it out to a 434" All motor monster. With a custom hydraulic roller cam from Cam Motion and 273 cc Brodix BR7s spec'd for road racing, shaft rockers, and in-house ceramic coated pistons/chambers, this engine made 750+ HP N/A on pump E85 and easily spins to 8200 RPM courtesy of a BTR Trinity intake. With the smaller 273cc intake runner and 2.205" valve in lieu of the 2.250 valve, it has an incredibly flat TQ curve and has seen lots of street miles with no drivability issues at all.
