This is the LT1 cam from the corvette with manual transmission.
The Camaro LT1 and impala/caprice LT1 got a different milder cam
3 different cams in the LT-1 motor depending on the car and trans used.
These 5.7 liter 10:1cr+++ high perf corvette Lt1 motors got a special high stall 2200stall converter.
That converter stalls about 1600 behind a lil 305.
not enough stall .
Go out in the driveway and stall test your converter against the brake.
I bet it cannot get past 1500rpm.
