I wondered if I could get Tech help to check these numbers for me. The numbers on the block are 11R143970 & T O204CJD Teh Vin number is 136371R143870. This car, I hope is a true SS. It does not have possie track and it has a 350 in it. Thank you for your help.

Well bad news kind of...after 68 there is no way to tell from the VIN if it is a true SS. You'll need to find the build sheet to prove for certain if it is an SS. Some ways you can get a good idea if it is are to look at the suspesion if it has a rear sway bar that is a + then also have the SS badges on the fenders grill and rear bumper, also there should be the SS badges on the door panels and steering wheel. The car should also have the SS dash with round gauges. Take a look at my 71 SS 350 on the link bellow. Oh BTW don't get dissapointed if people tell you its a Malibu all SS cars after 68 are Malibus (13637) they did this to fool the insurace man.

CJD suffix code means it should have been a 1971 4 barrel 350 with a turbo 350 behind it. Positraction was optional and it should have a 10 bolt 8 1/2 rear end.

11R143970 This is how to ID the engine to the car, if the division (1), Year(1), Assembly plant(R) and the last 6 digits match the car VIN then its the original engine.

1=Chevrolet Division
1=1971
R=Arlington assembly
143970=Car sequence number, last 6 digits.

TO204CJD
T=Tonawanda Engine Plant
02=Feb
04=day
CJD=1971 Chevelle 350Cid/270hp w/4BC rpo L48

Vin number 136371R143870
1=Chevrolet Division
3637=Malibu Sport Coupe
1=1971
R=Arlington Tx assembly
143870=sequence number and would also appear on the engine, the 11R143970 I bet is really 11R43890? Look again, if it is this is the original matching numbers engine!

As you can see nothing here will tell you any options and the SS was an option not a model. You will need paperwork to authenticate a SS, sure you can look for all the obvious SS equipment but even that can be retrofitted by knowledgeable persons. There is info on this site to help with that and I won't get into it. All 1971 SS had 12 bolts with the exception of the the L65 350/2bc SS with a manual tranny (not a 4-speed). This engine you have is a L48 and should have a 12 bolt. Posi was never standard, it was always an extra cost option. If no 12 bolt is present I would start to become suspicous otherwise chances are good its a SS if everthing else is there.
