Balancing China Engines

Could The China Engines Be Balanced By A Professional Shop ?? Thanks Ron

WHEN RACING FORD 427 CI TUNNEL PORT ENGINES WITH STROKER KIT (428SUPER COBRA JET CRANKSHAFT = 454 CI) I BOLTED MY MOTORS IN STEEL TO STEEL, NO RUBBER MOUNTS, IT MADE THE FRAME STRONGER. THE BLOCK BECAME PART OF THE FRAME. I COULD NEVER FEEL THE DIFFERENCE. THE MOTORS WERE PRECISION BALANCED. MY RACING BUDDIES SAID IT WOULD NOT WORK ! THE NEXT YEAR A LOT OF THEM WERE DOING IT (1974). WHEN I REV`D THE ENGINE IN THE PITS, IT WOULD ROCK THE CAR AS SCARE THE CHEV`S I HAVE A RETIRED FRIEND DOWN THE RD THAT BALANCES RACE ENGINES ETC. I WILL TAKE A CHINA ENGINE DOWN THERE. I HAVE ONE THAT CAME WITH THE EBAY SALE THAT HAS THE CYCLINDER OFF. WILL POST WHAT I FIND OUT. RON
