I HAVE A 2003 LS1 IN MY 57 CHEVY AND LOVE IT... THESE LS ENGINES ARE BULLET PROOF COMPARED TO THE OLD SCHOOL STUFF... A GUY IN TOWN HAS ONE IN A S10 WITH A BIGGER CAM AND SPRINGS,, RUNS 10.80 AND DRIVES IT 120 MILES ONE WAY TO THE TRACK AND GETS 20 MILES TO THE GALLON... THIS IS WITH A 900.00 JUNKYARD MOTOR
A STOCK STYLE NODULAR LS CRANK WILL HANDLE 600 HP
STOCK RODS WILL HANDLE 550 HP
THE BLOCKS ARE 6 BOLT MAINS AND WILL HANDLE 700+ HP
THE HEADS STOCK HAVE HUGE INTAKE PORTS AND BREATH WELL..
RIGHT NOW YOU CAN BUY THEM IN ANY JUNKYARD FROM ROLLOVERS FROM 300.00 TO 1200.00 DEPENDING ON MILEAGE... I HAVE BEEN RUNNING OLD SCHOOL MOTORS SINCE 1990 AND THESE LS ENGINES PRODUCE WAY MORE HORSEPOWER....OPINION
