Building it now, 2.3L ST replica motor for my '69S:
Fully detailed small spigot 7R case (shuffle pins, squirters, light mooning, every oiling mod known to man, etc)
85mm JE pistons @ 9.5:1 CR
'69S heads - ported by Dick Evelrude
Twin plugs (still debating which system to use)
DC44 cams (custom grind; .490 lift at both lobes; 102 deg lobe centers)
Titanium valve retainers
RARE 47mm 4-bearing cam carriers
Nickie cylinders
Rebuilt 2 liter 'S' rods w/ ARP bolts
Cross drilled crank
Fully balanced internals
Fresh 930 oil pump, with full race chamfer on the internals
2.4S MFI pump
52mm>38mm (taper bored) magnesium MFI stacks and match bored and rebuilt TBs
Lightened '69S flywheel
Planned to be good for between 210 and 220 HP (crank) at 7800 RPM.
