Z28Horn

Hey guys, I just recently installed a carbed 355 and a T-56 from a 94 Z28. Now i don't have the shifter on yet, but i think i left it in gear, not positive though. The car is jacked up and I cannot spin the motor over with a ratchet unless i press in the clutch pedal. But when i push in the pedal, my buddy said he was spinning the motor over pretty easily. Now, after this i got under the car and i could spin the driveshaft freely. What is going on here, is this normal? I need someone to help me out here.

Thanks guys,

Zach
