i have a 1992 camaro with the 305 vin E. i just bought a used 350 tpi with wiring and computer. i do not know what the vin of the engine is. so how do you figure it out? i have a flywheel but the mounting bolts are too big in diamater. so when i go to the junk yard what vin am i looking for for the smaller diamater crank/flywheel bolt pattern.

 

Is the end of the crankshaft round, or does it have corners on it?
