DONT GO BACKWARDS, OVER SIZED THROTTLE BODIES ARE IN MOST CASES A WASTE OF TIME AS THE ENGINE CAN ONLY SUCK WHAT IT CAN BLOW, THE ONLY TIME IT MAY BE NOTICEABLE IS AT TOP END FOR THE LAST 5MPH BEFORE YOUR ENGINE BLOWS AND THATS WITH A FILTER AND EXHAUST SYSTEM. TO OBTAIN THE BEST FLOW YOU NEED TO GRIND THE CAMS AND PORT OUT YOUR HEADS, EVEN GIVE THE VALVES A TICKLE THAN YOUR LARGER THROTTLE BODY MAY HAVE SOME AFFECT. BUT THEN AGAIN WHILE YOUR PAYING FOR ALL THIS AS WELL AS THE TIME OF THE ROAD MOST PEOPLE ARE OF BLOWING AIR DOWN THE THROATS OF THEIR CARS.
