Hi all and Happy New Year. Chasing some knowledge on the Eh and 149 motors. I am picking up my old mans EH ute that has been in the family since 1973. During her working career she has been around the clock twice and the motor reconditioned twice. I am wondering how I can be certain that the motor is original or not. Looking at the rego papers it is down as 492033. Looking at the block it looked more like Y92033. Does anyone know the engine numbering for the 149's?

Y is a low compression 149. The rego papers are wrong. The only way to be certain the actual engine block is original is the original owners service manual, or you can contact the AOMC and they may be able to do a rego search for a fee. 92033 would make the approximate date of the engine about February 1964. If it is old or rare - Cut it! http://www.ehlimo.com.au/ |

Hi Pete, Thanks for that info. Excuse me for my ignorance but AOMC stands for? The head casting number is 7420081 and doesnt have the usual L or H in the casting. Do you know the correct head casting numbers as well? The old man doesnt have the original log books so Im not sure of the date of manufacture. The chassis number is down on the rego paper as EH8004P. The Build plate is as follows and hopefully lines up with a Feb 1964 built motor:
Model: EH2106M-1777-A (Is this for Adelaide?)
Trim: 575-C58
Paint 568-5082

Hi H81837Q
I dont have many accurate figures on Perth assembled cars but the numbers look OK as an original car.
Firstly, all Perth assembled cars (with a few exceptions) had their bodies built in Adelaide. Hence the A on the body plate.
Secondly an engine serial number of 92033 places the car around one third way thru the EH production, so Feb 64 is reasonably close. 149 & 179 engines shared the same numbering sequence.
Im not sure how many EHs in total, were assembled in the Perth plant but 8004 also sounds around the money for this car.
Lastly the paint colour should be Budgeree Green & the interior trim should be in Triton Green.
Dr Terry.

Thanks Dr Terry. I was wondering about the A and The P and that explains it. I am in Perth and the old man said it was a Perth car. Thanks for the colours as well. The car has always been a Pale Green colour with a dark green vinyl interior for as long as I can remember. Im going to restore her to original specs since she is all there in original form. This car is like a family heir loom, I learnt to drive in the old girl 20+ years ago. Looking forward to fixing her up with the help from the old man as well, he can no longer drive the old girl as his knees are cactus. Does anyone know how I can get hold of correct numbers for head, manifolds e.t.c?

Hi H81837Q. There are a lot of date coded items on a old Holden. If you have a look at these pictures. http://s872.photobucket....Date%20coding/?start=allIt shows where to find the date codes on some of the things that are date coded. Some are related to what you want some are from later models but they will give you a idea as to what to look for. From these you will be able to tell if something has been changed or not. On the head side of things the date code will tell you a accurate date but I have 7420081 listed as a 179 and early 186 head. The H or L stamp on these early heads are on the left hand front of the head behind the thermostat housing. I have the 149 head listed as having casting number of 7420109. Cheers Paul.

Hi Paul, Thanks for the link to pictures and the info. Im a bit fussy with this stuff and I want to make sure I have the correct period parts on the car, thats just me!! Maybe there is a GMH EH Parts catalogue out there somewhere. Ill have a look for the date coding on the head the next time Im at the old mans and get back to you. Cheers

The 7420081 head was fitted to both 179 & lo-comp 149 engines. That is precisely how they got the low compression. The Y engine number prefix also signifies that it is, in fact, a lo-comp 149 engine.
IMHO those numbers all match. An EH with its original 149 lo-comp engine is a very rare item these days.
Dr Terry

Thanks Dr Terry. Im just trying to make sure, Dad said it was the original motor but its been recond twice and you know what happens when you send a motor for recon, your lucky if you get the same one back. Im pretty sure the head doesnt have any L or H marking on it. Its certainly not in the same place as the 186 motor as Ive checked. It has the casting mark but no L or H in the center. Very weird. Ill see if I can get some photos of the numbers and markings on the head and block. Edited by user Saturday, 16 January 2010 12:38:48 AM(UTC)

Thanks for the update on the head details Dr Terry. Can you ID some of these other ones correctly that were discussed here on O/H. http://oldholden.com/node/78628So the 7420081 was a low comp head as the 149 7420109 head was a high comp head is that correct. H81837Q. I have just added two more pictures on that link that show where the early compression cast code can be found. Cheers Paul.
