I see the Mod rules says that a KG4 is a legal engine in AMH.Does anyone have a picture of one?They must be heavily modded to run against the hotrods and 20h.Thanks

KG4 in AMH

Used to be that the KG4 was the A motor (along with the 15" Hot Rod).... I don't know what the rules are now but the Mercs had to be pretty heavily modified to keep up with the Hot Rods back when A motors ran in A class and B motors ran in B class. Take a look at George Stillwill's site to see some modified A Mercs....
OMC FE/SE powerhead parts for sale. Kurcz ported block, Mod 50 pistons and cylinder head, exhaust, etc.

Here is one that I run still not as fast as the hotrods but does run good. KG-4 block and Turner pistons and everything else is MK-25 opened up. You can do most anything to the 15 cu in Merc motor in AMOD.Destiny is a matter of chance,it is a matter of choice; it is not a thing to be waited for, it is a thing to be achieved.

15 cube legal with ANY mods/exhaust......Merc foot
20 cube legal (Stock powerhead),......with chamber.....closed/canned-muffler megaphone.....or the commode/conversion....Merc foot
These are a ton of fun to play with at 15CI..... but are a half lap behind a piped 15H/R.....on a good...er lucky day......On a hydro.
On a runabout .......the 20Merc/commode is close.....Saw Billy Allen and several other "commodes" up front a few times.
The Merc's "Achillie's heal".......apears..... to be it's heavy flywheel....That much mass will only spin/RPM so high compared to the H/R Motoplat flywheel...See George'
s Motoplat conversion above......very cool!....I've tried to make the Bendix mag with a cut flywheel work but very tempermental!
Plus the rotary valve control'd induction/radical square ports on the 15 H/R produces about 1/3 more HP than the reed cage and drilled round ports of the Merc.
The Merc was a mass produced fish'n motor.........I don't think(?) ya saw many stock(?) motoplat sparked Hot-Rods troll'n............
The A/B ......Merc vs H/R rivalry goes back several generations and is still deeply rooted........It was that competition (Speel check!) that inspired "o'l Iron Fist"/Carl K. to have his engineers dig in and come up with the 20H conversion (Freddy Bieger 100N often talked about Merc engineer Charley Strang and the 20H Conversion)
The same competition that inspired Carl K. to build us the 25SS to go after the Yamato Y80?....The 25XS vs the 102....and the 10XS vs the OMC 10/15?
Dang those must'a been some FUN times.............

Of course a lot of that could be the driver, I suppose
