That Vette should have a 350 c.i., 270 hp engine with manual transmission.

It really doesn't matter what's there now, that's possibly a restamped pad, and not a very good one at that.

There should be no 'grinding marks' going from side to side on a pad .

What is really "throwing" me, is the c at the begining of the
vin sequence. I notice that some 71s have it, and some don't.
I'm starting to think it was only used on early 71s.
Very confusing!

No way those numbers are legit. Are you sure it's not an '81?? It's probably an engine from a passenger car.

'71s Serial Numbers: 194371S100001 through 194371S121801

Here's what a '71 should look like:

Could those (grinding marks) actually be sanding marks, it looks like the guy sanded the paint off to allow pictures to show the numbers.

I'm just asking.

The pad was not painted to start with, so there would be no need to sand it. If the owner was trying to make it pretty and shiny, he screwed himself good.

For 1970, pad stamps were 70S4XXXXX. For early 1971, stamps continued with the same format, 71S1XXXXX. Starting in Sep 70 sometime 71s changed to C11S1XXXXX. That would be correct for this car. I'm no expert and it's tough to tell from pictures. My guess is that the side to side is from sanding and I'm voting for it's original.

I have good reason to believe mine is original, but repainted just before I bought it. So, my pad has a nice glossy orange coat of paint. I can read the numbers clearly though. If I wanted it to be "correct" then how would a person go about removing the paint and not leave scratches, etc.?

Paint remover! If it's really thick and stubborn DOT3 brake fluid will do the trick. Be very careful as it it will eat any paint anywhere!

It is obvious from the paint shown in the groves in the numbers that someone repainted the motor.

In my humble opinion that pad is original as are the numbers stamped on it.As to whether it is from 71 vette, I'll leave that to the numbers guys.

Try the NCRS.

Pad looks good to me. Obviously painted at some point and perhaps the paint was removed with sandpaper. The CJL code after the second set of nukmbers indicates that it is a base engine 350 270 HP with a Rochester quardrajet and a 4Speed. This is typically not the engine combo you would want to fake with such a high caliber stamp. There is just not enough money in the base engine option. If it was a big block I would be a little more concerned.

Your engine should have also the numbers 3970010. That imply a 350 c.i. engine. CJL code are only for 1971 Chevrolet 350 c.i. engines.

There was a strike at St. Louis from about mid-September 1970 through nearly the end of November. My finacee's '71 got caught in it. Casting numbers and VIN all point to what should have been a late September build date, but her car ended up with December 1 build date due to the strike. Her block is not stamped with a "C" code. After the strike, '71 blocks began to be stamped the with "C" characters. The '71 Registry has additonal information regarding block stampings. The NCRS Judging Manual also helps.

Aha! So that's why there's confusion. Good info...

I have a similar question on my 1970. What does the V0202CTD indicate on the engine pad besides 350, 300hp? Also what does Chevrolet 828 mean on the VIN plate? Thanks.
