how much is a l16 with a87 and auto

[Arkrider410]

I'm getting a ka24de and don't need the l16

[Dolomite]

Not much. The auto trans is worth literally nothing.

[Lockleaf]

Oil pan, valve cover, engine mount brackets are worth more than the rest of the engine. If it's a good running setup, you might get 150 for everything from a guy who just wants to be up and running.

[Arkrider410]

So the parts are worth more than the whole thing

[Arkrider410]

so the trans is worth the price of aluminium scrap

I don't know why anyone would put an A87 on an L16. If closed chamber, the compression drops to 8.21 from 8.5. If open chamber it drops all the way to 7.72!!!!

[Arkrider410]

I didn't do it

[datzenmike]

I know. POs are a strange bunch.

[Arkrider410]

I think it's stock

[datzenmike]

No. The L16 only came with a 210, number head. The A87 was an open 45cc combustion chamber, (for use will larger displacement L18) some were closed 41cc from import engines. The 210 head is 38cc. and gives the 8.5 compression.  Possibly it was shaved down to raise the compression back up. The bottom of the A87 may be shaved off.

Are you sure you have an L16 block with an L18 head.  Maybe it's an L18 lower and upper. Show pics.

[Stoffregen Motorsports]

Yeah, if it's an L18, the block alone could be worth some serious bucks. Vintage racers use them as they are the only "legal" engine displacement upgrade to a period correct B-sedan or 2.5 Trans Am racer.

[Arkrider410]

Numbers on the block are l16 numbers on head are a87

[banzai510(hainz)]

On east coastmay be worth something. Not much here in Northwest.  I give them away

Unless you find a purist who wants to take the Datsun back to stock, they aren't worth much. I just got one in new england for essentially free (with a bunch of other stuff), because it had Z flattops, mild cam, aluminum flywheel, and I think less than 10 mi on it, lol.

 

THe head is worth something certainly! California Datsun tries to get $600 for that head all prettied up.

[Draker]

I think the money is in that head.. assuming it's a closed chamber head. It's been shaved though. 

[datzenmike]

 

 

This head has been shaved to raise the compression. The bottom of the A87 is chopped off.

 

I don't know why anyone would put an A87 on an L16. If closed chamber, the compression drops to 8.21 from 8.5. If open chamber it drops all the way to 7.72!!!!

 

No way Nissan would have run that low a compression. So they must have shaved them or they didn't run them.

 

 

 

No. The L16 only came with a 210, number head. The A87 was an open 45cc combustion chamber, (for use will larger displacement L18) some were closed 41cc from import engines. The 210 head is 38cc. and gives the 8.5 compression.  Possibly it was shaved down to raise the compression back up. The bottom of the A87 may be shaved off.

 

 

Unshaved...

[Stoffregen Motorsports]

To clarify the casting number thing, just because the numbers don't show in full doesn't mean the had has been cut. Casting shift happens during the setup process and a lot of heads came out with the bottom of the numbers cut off.

[racerx]

He needs to measure it

[datzenmike]

Anything's possible but the only ones I have seen here that were cut off were milled down.

 

A87 combustion chambers are open... 45.3cc or closed.... 41.

 

As far as I'm concerned they were not used on an L16 because of the much lower compression ratios produced. If as Doug says they were used on the '73 L16 then it's assumed that they either had very poor compression or were milled down to raise them back up.

 

An open chamber A87 would need 1.2mm or about 0.050" milled to remove about 7cc of chamber volume.

 

 

This is all just a thought experiment. If you want to know what head you have, open or closed, take it off. If you want to know the combustion chamber volume.... http://community.ratsun.net/topic/358-how-to-cc-your-cylinder-head-for-free/

No, 1973 L16s came with open chamber A87s.  Every '73 L16 I've seen that matched the engine number on the dataplate had an A87 head, both in 510s and 620 pickups like my Mom's '73 620, which she's had since new and the engine and head are original.  Whether the pistons have less dish than the 210-casting head L16s I don't know.

 

But import L16s came with W53 heads as well.   The L16 was manufactured into the early '80s for replacement engines as well as non-American markets, but the 210 head was pretty much done after the 1972 model year.

 

There are a lot of "specs" posted on what heads have what chambers, valves, and ports but reality is they vary widely even from casting number to casting number.  There are open and closed versions of almost all heads- if you look closely, they were ALL cast as a closed chamber head and then some were machined open at the factory to lower the compression so that American crappy sub-90 octane gas could be used for emissions purposes (higher compression caused higher NOx emissions due to higher combustion temperatures).  

 

But for proof that the "specs" given for Nissan heads isn't always right, I have a 219 head sitting in my garage with 1.38" intake ports.  Every manual, list, etc says that 219 heads have 1.50" intake ports.  It was a stock head off a Central American L14 engine.

[Stoffregen Motorsports]

That's a solid point. Going off North American specs does not take into account the thousands of imported engines.

 

As far as I'm concerned, the only way to know what combustion chamber, valve size, port size or thickness a cylinder head has is to visually inspect it and take measurements.
