Know what you have. Small block Mopar engine identification.

[@brokendad2222]

I had a 73 Duster with a 340, in the late 70s, I was a regular shopper from the old direct connection catalog. Factory speed parts, for a twenty something guy you just don't get much better than that.

[@Duster_Garage]

That was a great time to be a Mopar guy.

[@rustymyers5934]

That’s very interesting! I was never aware of how to de-code an engine. Thank you for the clear breakdown.

[@Duster_Garage]

Yeah, no problem

[@bumdodge1]

Mopar don't confuse with codes

[@sunriseexpress4961]

Great video, thanks for putting this out here and taking the time to explain.

[@Duster_Garage]

Thanks. I’m by no means an expert but hopefully it helps someone.

[@DJTruth_1970]

Have a 71 Demon 340 block in my garage to build for my 74 Duster. Started as a slant 6, built a 318 and installed as my daughter drove it to high school. P/S, P/B & A/C car. Currently doing a lot of work to my 70 Chevelle SS 454 now.

[@Duster_Garage]

That’s awesome, build it the way you want it. That’s what I do.

[@DJTruth_1970]

@@Duster_Garage I built mopar race cars and restored old mopar a for a living for 30 years. Definitely gonna do it right. I’ve had the Chevelle since the mid 90s and completely redoing interior and replacing all sheet metal from windshield forward. On the downhill slope now. Drivetrain is a new 500 inch motor, 400 trans and 12 posi. Fun to drive

[@Duster_Garage]

@@DJTruth_1970 nice! She sounds like a ground pounder.

[@TrevorThomas31]

Awesome. I feel like you could also find the riddle of steel somewhere on there, too. Minus Tulsa Doom and a cliff jumper.

[@Duster_Garage]

Conan reference, nice!

[@leorodriguez6917]

Excelent video thank your for the time, so my friend a question, where I Can find pdf with this kind information ? Specially manufacturing date , thanks for your support

[@Duster_Garage]

I have been searching online for a pdf of engine block stamping decoder. I couldn’t find the exact one I used in this video. I did find a casting number chart that may help you. www.mymopar.com/downloads/Mopar_Drivetrain_Numbers.pdf

[@leorodriguez6917]

Thank you for your support I appreciate it and I did a screen print too 🤷‍♂️😅 thank you again

[@rustyrobinson8027]

Thanks for that useful information

[@Duster_Garage]

No problem

[@70stunes71]

Thanks for the #'s rundown. 👍💯

[@Duster_Garage]

No problem

[@70stunes71]

@Duster_Garage Took apart the numbers matching 383 to my '69 bee this week. It's been out of the car since the 70s. Not my doing but #8 rod journal slightly spun, no deep grooves thankfully. I built a 440 and put in it instead, saving the factory 383 for whomever down the road when I'm gone. If these old cars could talk...lol

[@henryknedel5683]

There's also markings. Time n Shift made. Number of repairs done to casting mold.

[@Duster_Garage]

That’s pretty cool

[@stannelson2582]

I’m going to look tomorrow thanks

[@Duster_Garage]

That’s cool. I hope it helped

Great video!!!

[@Duster_Garage]

Thanks brother!

[@AbodyTomsgarage]

Awesome bud

[@Duster_Garage]

Yeah man

[@jamesharrington4923]

Hey man thanks for the info on small blocks, does the info go for post 92 318 and 360 too???

[@Duster_Garage]

I think so, I just don’t think it will be stamped on the front of the block.

[@jamesharrington4923]

@@Duster_Garage I gotcha, do you know how rare a 76 dodge dart Lite is?? SL6 4sp??

[@Duster_Garage]

@@jamesharrington4923 without looking up exact numbers I’m not sure. But I know they are rare.

[@jamesharrington4923]

@@Duster_Garage yeah I know , it would make a great small block 4sp car

[@Duster_Garage]

@@jamesharrington4923 it would, they are very light weight.

[@davomg9]

Are you able to decode my 340 engine block for my 71 duster?

[@Duster_Garage]

Maybe. what alphanumeric stamping do you have on the left front side of your block?

[@davomg9]

Mine is just above the oil pan rail since it's a 68. The code is BH23P9P140324. The second P could be a B hard to tell

[@Duster_Garage]

@@davomg9 it’s the vin of the car your engine came from. B - Barracuda H - ‘68-69 Barracuda 23 - 2 door coupe P - 340 4 bbl V8 ‘68-69 9 - 1969 B - Hamtramck, MI assembly plant 140324 - sequential production number

[@davomg9]

That's awesome I appreciate it very much is there a book I can buy? I have a set of X heads I would like to decode

[@Duster_Garage]

@@davomg9 there might be a book. I’m using an old Year One catalog. I’m sure you can find something online that would decode the same.

[@janbill79]

on same subject but, lots newer/ the dodge/ Plymouth engine, I have a 2.0 4 cyl. from a junkyard. wasn't the year they said it was/ Well it did come out of a 95' neon ( but the guy put it in there from some other car, Unknown car unknown year/ but the aluminum oil pan means 2000 to 2005. the casting codes that I found under frost plug when starter is removed say first top row says D N MIDDLE ROW HAS DASHES LIKE A DATE CODE EXCEPT STATS WITH 0 0-07-0 BOTOM ROW SINGLE (9) ON LEFT & AZ ON RIGHT IS THERE A MAGAZINE THAT TELLS DODGE 1995-2005 CODES THKS, IF SOME ONE KNOWS

[@Duster_Garage]

@@janbill79 I don’t know of any but you probably could find it online.

[@janbill79]

@@Duster_Garage I've wasted a lot of hours all ready. Only muscle cars from 70's are talked about. I'll switch over to looking for part numbers from block and head. And buy some part books, or see if a dodge dealer would look them up. The dealer said to me,( but I don't know if he meant in the last decade or 2 or what) but he said there are no more part books. Only hard drive records.
