1992 camaro that came with L98 auto. G92 body obviously. Now has a 350 4 bolt. Block says its 1969-1978 truck or corvette. I swapped in a T5 from hawks third gen. with a 1985 corvette flywheel to fit with larger crank. I have a 2.73 non posi in the rear. from a 1982 camaro coupe which had a 305 with the metric 3 speed auto. T5 is Borg-Warner/Worldclass.

NOW...why am I in 5th gear...60mph...and the tach says 3,000 rpms?

The motor is carbed...distibutor is vacum sec.

wheels are 16 stock alloys with 245/50/16. what is up?

ALSO...when at idle. she reads 1,000. I turned it up when I did the 5 speed swap. So it makes me think the tach is right....but could the tach be off as it climbs higher?

 

Either the tach is wrong or your gear ratio is shorter than you think. Most likely the tach. they're known to be inaccurate.
