... today began attempting a Log manifold 2Bbl mod' for Blow-thu 2300 / 7448 carb . Adding to challenge, prefer build without carb' fuel bowl above Exhaust manifold as a rule. Current 2 X 1 adapter limits boost performance,
.
typical angle grinder cutter wheel worked the cast manifold easily and larger 8" flat grind wheel got it almost flat carefully with a straight edge.
, . V
futile try at drilling the cast for 2nd carb port with quality hole saw didn't get far, enlarged ports for 1-1/2" carb throttle bores with a small stone on a drill.
.
the curing epoxy was added to edge for increased gasket land width
... tomorrow may try 'casting' an @ 1/2" thick spacer / riser from manifold to the alum. 1" spacer used as carb port gauge.
Spacer/ riser would be best to match original manifold slant to level carb.
3D printer would probly' make simple, may try epoxy or 2K panel stuff i have .
.
issues ?
> casting is very thin where tapping needed for some carb riser fasteners? .
> what casting material to be used for a wedge shaped riser/spacer ?.
>what angle front to back and is level correction really needed for carb anyway ?
continue attempt after epoxy cures tomorrow ...
suggestions / info appreciated, anecdotes - not so much...
have fun
