Re: Help with engine partial vin#

For your application :
CLB = 72 402 Chevelle 240 LS-3 TH-400 4-Brl

The partial VIN is for the vehicle ,not the engine
1 1 S 247929
1 =Chevrolet
1 =1971
S = St.Louis assembly plant
247929 =plant sequence number

3999290 = 402 72 2-bolt
F-21-71 = June 21,1971 casting

3993820 = 402/454 71 2.06/1.77 113cc Oval port
D-27-71 and F-11-71 =April 27,1971 & June 11,1971

3866948 = 396/427 66-67 Holley Oval port L-34/L-35
H-18-6 = August 18,1966

Re: Help with engine partial vin#

A CLB code 402 was also used in the full size cars, which could have been built in St Louis and that would explain the S in the partial VIN.

Re: Help with engine partial vin#

I looked on nastyz28.co m for the suffix code..but the vin does come back to a 71..and there it says 71 chevelle 396 or 402
and 1971 monte 396 or 402..

sometimes it is confusing..I also have a 1970 LS5 454 out of a monte carlo ss It has CRN on the pad..standard bore with stock pistons. How rare is that one?

Re: Help with engine partial vin#

So it is a late 1971 motor due to the VIN being a "1" there..The vin is on the pad front of right head.

This is one of those gm things..around this time..with strikes..ect..

I had a 1983 Z28 here..was a Crossfire car..5 speed..and had a factory dana44 3.31 posi rear disc brake in it...Axle tube was dated 1983. I put it on ebay..sold it for $1227 just for the rear end..In 1983,if you ordered a camaro/firebird with posi option...Gm put dana 44's in a few hundred cars..the stock rears were not being made with posi's due to the strike..

I get this stuff all the time...lol

Too much mis and partial information given so far. The partial VIN stamping on the engine is indeed a 1971 Chevrolet passenger car. The "S" in the partial VIN is St. Louis. Passenger cars (full size Chevrolets) were built at 6 different plants in 1971:
C - Southgate, CA
D - Atlanta, GA
J - Janesville, WI
S - St. Louis, MO
T - Tarrytown, NY
Y - Wilmington, DE

See http://chevellestuff.net/misc/chevro...bly_plants.htm for more.

The intake, #3866948, was used on at least Chevelles in 1966 and 1967 but could easily have been used on other Chevrolet models as well. I'm at a car show and don't have access to all my resources. The date (H 18 6 - August 18, 1966) would indicate probably a 1967 model year usage. See http://chevellestuff.net/qd/intake_casting_by_year.htm for Chevelle specifics.

The heads were used in 1971 on both the LS3 as well as the LS5 and are dated April 27 and June 11 respectively. The same caveat here applies to the intake that the heads were probably used on other models of Chevrolets as well as Chevelles. See http://chevellestuff.net/qd/head_casting_by_year.htm.

I don't find a 399290 block but do find a 3999290 used in 1972 but could have gone into service in late 1971. See http://chevellestuff.net/qd/block_casting_by_year.htm.

Again, my resources show the CRN stamping a Monte Carlo only engine ID code for a 1970 LS5. According to the First Gen MC website, http://www.firstgenmc.com/tech/productionnumbers.shtml, there were 3,823 LS5 SS-optined MCs in 1970. Probably (maybe) worth more to a MC enthusiast than anyone else.

Re: Help with engine partial vin#

Could it be that the st louis plant ran out of motors..on line,and got a CLB stamped motor and put it in a fullsized? Mabye someone special ordered a fullsize with a CLB 300 LS3 motor? It is a wierd one for sure..That is why i am asking..71 was a strike year for gm..They did wierd things..Truck load of motor may have went to wrong plant? I just dont know...lol

The monte motor i know someone needs that one..Thats why i bought it years ago. I just dont want to put that LS5 in the 88 ...it will be fun..but it deserves to be back home in a 70 MC SS

This site is great..tons of info here,thats why i joined here..

Being this is stamped CLB it is still a LS3 motor..even if it was in a fullsize.according to vin..Man here is the truck it was in..

Most online sites show the CLB in a full size car in 1972 w/manual transmission but they could be wrong. CLB was a Chevelle & Camaro engine code for an LS3 so I don't understand the question I guess. Major components were lined up BEFORE the car was released for production so the question of would a plant run out of one engine and substitute another...I'd say no. The LS3 was available in full size cars in 1971 so it would be a normal option order, nothing special - 64,182 were ordered in 71 full size cars and 66,702 were ordered in 72 full size cars.

NO, that kind of stuff did not happen.

Before a car was released for production all the parts to build the car were on hand, then and only then would they have started production for the car. The assembly lines could not stop so they could find any engine from another plant.

If the VIN shows the car was built in St Louis then the motor is not a Chevelle motor, end of story.

Just because web sites say CLB is a Chevelle motor does not mean all CLB were only in Chevelle's, they could have been used in other models also and just never noted anywhere. Been know to happen.

Wrong for what? It is a valid code in and of itself.

Re: Help with engine partial vin#

according to the vin...it is
1 = chevrolet
1 = 1971
S = St louis
247929 is # of car..

so it will be a 1971 code CLB In my books is says 1971 Chevelle 396 or 402
Or 1971 monte carlo 396 or 402 depending on date on block F-21-71

While CLB was used in the Chevelle and Monte Carlo in 1971, neither were built in St. Louis, ever. Only full size passenger cars and Corvettes were built in St. Louis in 1971.

http://chevellestuff.net/misc/chevro...bly_plants.htm

And, FWIW, the 396 engine grew to 402 in late 1969 but was still called a 396 since Chevrolet has so much invested in the SS396 moniker. In many publications you'll see a 400-2 and 400-4 engine shown which cause some confusion early on. The 400-2 was the small block 400cid 2-bbl engine while the 400-4 was really a 402 and had a 4-bbl. Sometimes they were referred to as 400 Turbo Fire (small block) and 400 Turbo Jet (big block).

Re: Help with engine partial vin#

CLB is a valid code for Full Size cars, Chevelles, and Camaros. Since neither Chevelle or Camaro were built at St. Loius, it has to be Full Size. Corvette also came from St Louis, but Corvette didn't get the CLB coded engine.

The listing that says CLB is Chevelle isn't wrong, just incomplete.
