Engine Code Question
#1
  This topic is about my 1977 MG MGB

1977 MG MGB "Speckled Hen"
I suspect the engine in my 77 rubber bumper is not original to the car. Searched some past posts and it appears to be a 5 bearing, possibly a California car engine that had a catalytic converter...

code on block - 18V883AEL01479

Can anyone confirm what I think and maybe tell me more?

According to Clausager that engine was made Jun 1976-Oct 1980 USA( not California) with cat, without overdrive

To completely answer your question, the 883 AEL code does indicate a 49 state 18 V engine starting in June 76. Further the engine number started at 101. Your engine number indicates that it was probably built in July or Aug of 76 to be installed in an early 77 model car.

All non calif 49 state and California had cat converter after Sept 1975
Your number looks like correct period for your car
A heritage certificate would confirm if you really want exactness

Would a Heritage Certificate be the only source to confirm if the engine is matching to the car itself?
I've heard of 'numbers matching' vehicles before but didn't know what exactly was involved in confirming that claim.

A Heritage certificate shows the factory build information.

Its clear the engine is the correct series for the '77 model year. What else are you trying to determine?

I would like to know how to determine if the engine is original to the car.

All info points to that.
A heritage certificate will bear it out.
Read the replies. You've been told how

BTW all mgb engines after Nov 1964 were 5 main.
You have the tag,you know it's correct time period for your 1977
It a generic low compression 18v that all after 1975 in the US came with smog equipment and cat converter. Why the interest if it's the original engine? Makes not a wit of difference.

It's called "Matching Number Syndrome". The Corvette and early GTO owners suffer greatly from it.smiling smiley
