This item is partially derived from disassembling brand new, never-run, engines and may show minor traces of having been mounted and/or minor tool marks.
Dual bypass ports
Sub-induction (SPI)
Dual booster ports (one per side)
(The same porting as TD #4 Cylinders )

Brand new Current Production item
These are special manufacture; whereas we took a "Production" cylinder, removed the bar in the exhaust ports and lowered the bottom port cut-out to induce SPI.
This cylinder will equal OEM Tee Dee cylinder performance and is currently our highest-performance cylinder but please note that they are not "tapered" and the piston can be slid through the top of the cylinder.
Inside of exhaust ports will be unplated (not oxided).
