I BOUGHT A FORD WINDSOR 347 STROKER KIT, PROCOMP ALUMINIUM HEADS COMPLETE, PLUS A LOT OF OTHER PARTS, FIRST PROBLEM, GETTING THE ROTATING ASSEMBLY BALANCED, THE CRANK WAS SO BADLY OUT OF BALANCE THAT I HAD TO PAY THE ENGINE BALANCER MAN $100 MORE TO FIX IT, PROBLEM NO 2 , THE PROCOMP CAM BEARINGS WERE RUBBISH, SO I BOUGHT CLEVELITE CAM BEARINGS ,AFTER ASSEMBLING THE PISTONS INTO THE BORES I FOUND THAT THE PISTONS WERE 40 TH . ABOVE THE DECK.SO I HAD TO GET 40 TH MACHINED OFF THE TOP OF THE PISTONS, THE HARMONIC BALANCER WAS LOOSE ON THE CRANK,GOT THE ENGINE TOGETHER, STARTED IT UP IN A CLOUD OF SMOKE, BUT IT NEVER STOPPED SMOKING BADLY, SO I NEW THERE HAD TO BE SOMETHING WRONG,REMOVED THE ENGINE, PULLED IT APART, HAD A GOOD LOOK AND FOUND THAT THE PISTONS THAT WERE SUPPLIED SHOULD HAVE HAD A SPACER RING SUPPLIED WITH IT, AND WITHOUT THEM THE OIL RINGS WOULD NOT WORK PROPERLY. SO I BOUGHT ANOTHER SET OF SPEED PRO PISTONS WITH THE EXTRA SPACER OIL RINGS AND THE CORRECT RINGS, FOR THE EXTRA MONEY THAT I SPENT I COULD HAVE GOT HIGH QUALITY PARTS FROM ANYONE BUT SPEEDMASTER, SYDNEY SPEED SUPPLIES, AT RACING WORLD AUSTRALIA. DO NOT BUY ITS JUNK, GOOD LUCK TRYING TO GET COMPENSATION. User's recommendation: DO NOT BUY THIS JUNK I LEARNT THE HARD WAY.
