Aircraft full fuel before takeoff. Obtained 2 WX briefings, one immediately before takeoff, one 2 hours previously. On IFR flight plan from tlh to sua (direct cty V159 vrb direct sua). Takeoff on right tank and climbed to 7000 ft in VFR conditions. Stayed on right tank for 30 mins. Switched to left tank for 30 mins. Near the 009 degree radial of pie where it crosses V159 between cty and ocf, we switched to right tank. Engine immediately ran rough. We switched back to left tank but the engine did not completely return to normal. So mixture rich, boost pump left on, and applied carburetor heat, noticing normal RPM drop. Took carburetor heat off and decided to continue to ocf at 7000 ft and spiral to airport. Shortly thereafter, an explosion in engine compartment, later determined to be left front cylinder, departed the crank case. Cowling broke both windshields and oil entered aircraft. We shut down engine, shut off fuel, squawked 7700 and got 1 mayday off to jax approach. Decision was made to attempt emergency landing on horse race track. Landing was uneventful with no damage attributed to landing.

Title: A CRUISING PA28-180 SUFFERS THE LOSS OF THE FRONT L CYLINDER HEAD WHICH DESTROYED THE COWLING AND WINDSCREEN. ACFT MAKES AN OFF ARPT EMER LNDG AT A RACE TRACK WHILE DIVERTING TO OCF, FL.
Narrative: ACFT FULL FUEL BEFORE TKOF. OBTAINED 2 WX BRIEFINGS, ONE IMMEDIATELY BEFORE TKOF, ONE 2 HRS PREVIOUSLY. ON IFR FLT PLAN FROM TLH TO SUA (DIRECT CTY V159 VRB DIRECT SUA). TKOF ON R TANK AND CLBED TO 7000 FT IN VFR CONDITIONS. STAYED ON R TANK FOR 30 MINS. SWITCHED TO L TANK FOR 30 MINS. NEAR THE 009 DEG RADIAL OF PIE WHERE IT CROSSES V159 BTWN CTY AND OCF, WE SWITCHED TO R TANK. ENG IMMEDIATELY RAN ROUGH. WE SWITCHED BACK TO L TANK BUT THE ENG DID NOT COMPLETELY RETURN TO NORMAL. SO MIXTURE RICH, BOOST PUMP LEFT ON, AND APPLIED CARB HEAT, NOTICING NORMAL RPM DROP. TOOK CARB HEAT OFF AND DECIDED TO CONTINUE TO OCF AT 7000 FT AND SPIRAL TO ARPT. SHORTLY THEREAFTER, AN EXPLOSION IN ENG COMPARTMENT, LATER DETERMINED TO BE L FRONT CYLINDER, DEPARTED THE CRANK CASE. COWLING BROKE BOTH WINDSHIELDS AND OIL ENTERED ACFT. WE SHUT DOWN ENG, SHUT OFF FUEL, SQUAWKED 7700 AND GOT 1 MAYDAY OFF TO JAX APCH. DECISION WAS MADE TO ATTEMPT EMER LNDG ON HORSE RACE TRACK. LNDG WAS UNEVENTFUL WITH NO DAMAGE ATTRIBUTED TO LNDG.
