Its a 454, 4 bolt main. Casting number 10069286. Its built in Tonawanda, 1990. It has 2 timing tabs on it. One in the usual spot on top and another on the bottom. It makes me think it is out of a motor home maybe.
Hey guys...need some help identifying a gm smb. To me the numbers look like TI2I2CSJ or T1212CSJ? Partial vin is 13C156006. Rear number is 3951511. Any help would be great thanks
1212 is December 12th. The casting date code on the back will help you figure out if that was in 1972, like I think it should be...look for something like L 10 2 the last digit is the year.
I got a small block with a date stamp of V0810ZZ3. I know it's from the Flint plant on Aug 10, but what is the suffix code ZZ3? I've been searching everywhere on the net, have not found that suffix code yet. Anyone?
yup, the first one of the series came out around 1989, 350 with aluminum heads, it was the ZZZ. Never installed in any cars by Chevy.
High Output 350 (ZZ3) PN: 10185072 Cost: about $3000 (includes many accessories, intake, distributer and water pump) Displacement: 350 cubic inches (5.7L) Horsepower: 345 at 5200 rpm Torque: 387 lb-ft at 3250 rpm Max RPM: 5800 Compression ratio: 9.8:1 Bore & Stroke: 4.00" x 3.48" Pistons: Cast hypereutectic aluminum Rods: 1053 forged steel "pink" Heads: Cast aluminum, angled plugs, 58cc Head specs: 1.94"/1.50" Camshaft: Hydraulic roller tappet Cam specs: 208/221 .474"/.510" 308/316 (advertised) Idle: 750 rpm
Guys, thanks for the help. Those spec's look pretty decent, I'm impressed. I thought it ran pretty good, that explains why.
My 72 Vette has a 350 engine # 3970010 on block/ C4f216377 V0801TKT on tab/ Casting # G183 I assume it is a 1973 350 truck motor? What does TKT mean and what is the HP? Also any way to tell if it is a 2 or 4 bolt. Thanks in advance for any help
sounds like you have it figured out pretty well. The HP rating doesn't mean a lot (145-175 depending on what TKT means, which is really hard to find out)....and it's probably a 4 bolt, and you can only be sure by pulling off the oil pan and looking, if it matters (which it probably does not).
C5f345256 V1206TY Iam trying to decode this 350 3970014 casting V flint 1January 20 day 6 1976 ? Ty suffix code ? Sent from my LM-G710 using Tapatalk
there's another letter after the Y (possibly a T? TYT is a valid code for 1975-77), it's a 1975 truck engine, per the partial VIN. assembled 1206 which is December 6th, 1974.
Figured it out its tyz truck is a 75 its a 014 block I think it is the original truck engine Sent from my LM-G710 using Tapatalk
I was needing some information on a 283 forged crankshaft I just got.The cast number is 3474,the research I did,showed it as a 283 forged military crank.
I recently acquired a 41Chevy 1/2 ton pickup. I believe the original engine was a 216, but I was told that it now has a 235. How can I tell? I found the engine # on the right side of the block, just behind the distributor, it is AD1076409. Hope you can shed some light. Thanks. JohnJ68
A picture of the engine would help. If the valve cover is fastened with screws around the edge, it is most likely a 235. If the bolts holding the valve cover are on the top of the cover, it is most likely a 216. The engine serial number does match to a 1956, 1957, and maybe later 235 with a heavy duty clutch. The engine casting number and the date code will be a great help in identifying the year and month it was manufactured. Here is an excellent site for decoding your engine. http://www.inliners.org/becks/BCN2.html Bob
Trivia: the LS-7 crate 454 that Chevy sold in the 70s and 80s has the suffix code XCH. Splitting hairs here but GM at least in the 1970's was pretty spotty in stamping codes and or serial numbers in some of the service replacement blocks and I can vouch for at least one LS-7 that went out of the dealership's parts department that I worked in without any stamped ID in the block. While not coming back to bite us the two police detectives were none too happy with us or GM as this particular engine was the subject of an investigation and we were unable to verify or deny that this particular engine was the one sold by our dealership.
I have a 68 Corvette 427 replacement block that has a serial number starting with CC plus the number. It is a 425 HP engine, and I couldn't find out how these replacement blocks were numbered. What is funny, is that every once in awhile, I get a call from some stranger that has found out I own the engine, and they figure I am stupid enough to sell it. Bob
I have a chevy small block casting number 14010207 (says its from 1980-85) with the engine id of V0512ACM I can't find what the ACM is for. please help I'm trying to find a dipstick the ones I have ordered do not reach the engine block where it attaches too.
you need a 1980-and newer dipstick. The 55-79 unit is for the other side of the engine, and is too short. Also it usually works better to just buy a new tube with the dipstick, so they match. also, look for the other engine number stamp, which is a partial VIN and will tell you what plant the car was assembled in. That might help you figure out what model of car it's from. post it here
Super Chevy Magazine had several articles with an almost complete listing to decode all the prefixes, numbers, and suffixes for almost all the small block engines. I had the complete list, but I have lost all but some of the big block stuff in all my paperwork. I am in the process of reorganizing my reference material, so I do hope to find the small block list again. Bob
