there can be two ways depending on the year it is either on the back by where the transnission bolts up or there is a spot on the front by the alternator but that will normally tell you if it is a truck block or car block and the place it was manufatured.
350 miles.
id say about.... 350
id take the rocket my self it has a little more power than the Chevy 350
The engine id is on a pad on the block located in front of the passenger side head.
Id say about 300-350 also depends on sights fix= less then nights.
id ask 200-400 depending on condition but prolly 300$$
You might be able to trace the id # (just in front of #2 cylinder) at mortec.com
The casting number 3970010 is associated with a Chevrolet 350 engine produced primarily between 1969 and 1979. The ID number v0202zaf indicates that the engine was manufactured in February 1970 at the Flint, Michigan plant. Therefore, your engine is likely from the year 1970.
I would venture to guess about 230
well first off the 350 is a small block so look at the exaust ports and if they are seimeze its a smallie, and if the ports are spaced evenly apart its a biggie for chevys anyways. there would be stampings the block. hope this helps
there should be a numbered stamped on the rear of the engine
Sometimes you can find information at mortec.com and http://www.nastyz28.com/chevy-engine-code-stampings.php
