In other words, if I wanted a 242 motor - B23E - what year were they sold in normal 244 - I seem to recall it was about 81 to 83?

81-84
85 = b230e

Lovely work! Thanks

What is it you need? What car do you currently have for it to go in? The higher comp is an advantage but most of the work is from the more aggressive camshaft, if you have a b230F in a post 86 240, fitting the K or H cam would wake the motor up and not need all the work for converting to a motor that didn't use EFi.
And the later motor is a better internal design as well. Power differences with the same "K" cam are about 2-3kw's, though it would still only be making 68 rear wheel kilowatts with a manual...

Hey, I have a manual 78 and know where there are a couple of 83 cars with engines, so I just was thinking of doing a swap.

'81 to '84 had the B23E, for the '81-'83 model years they had the 405 casting head and K cam, with advertised 136hp, for '84 they had a 398 head and an A cam, power was slightly lower as a result, 129hp rings a bell. '85 had the B230E which still had K-Jet/CIS injection, then from '86 on they had the B230F with EFI.

The 79 gt's had the first 2.3 ltr. 405 casting head, h cam lighter flywheel.

Who told you about the lighter flywheel? That's a new one.
You can tell a GT B23E block apart from a regular '81-'84 B23E by the lack of an area cast into the block for a breather box, as they had the same breather in the valve cover as the B21 engines.

I have the engine out of my gt at the moment and the flywheel is machined in a dish on the back. I will compare it to my standard 240 flywheel I get it off the stand. I lightened this flywheel heaps.
Angus242164
They're normally machined out on the back to form a bit of a dish, pretty shallow, about 5mm roughly.
I just had a look at your project thread for your GT, it looks like you're making some good progress with it.

IIRC the B21E was sold until 1980.
smithy
not in the GT's

OP didn't mention a GT, he asked what year B23Es were sold in 244s. The answer is 81-84, with the more desirable ones in 81-82.

Sorry
