stuck in gear
my four speed standard is locked in gear how do i fix

The 1976 Chevrolet Corvette did not show many changes since the 1975 model. One glaring omission: the convertible was no longer a choice. Buyers could select a Corvette with a T-top, but other than that, options seemed more limited. This model was not very popular with much of the community, as the steering wheel was identical to the unloved Chevy Vega.

I recently bought a Corvette to restore for my 10yr old Grandson. The 1 I bought has a radical...I mean radical, racing engine. I want to put a Chev. in line 6 cylinder in it, because the insanity must stop with horse power! Do you have any idea what 6 cylinder engine to use? Plus would I need to also change the Transmission out?
new gauge and sending unit. When starting the motor the gauge pegs out and stays pegged when the motor is off. When turning the switch back on it goes to 0. Then start it and it pegs out. Gronded the sending unit with no change.
