metalmonkey47 Posted June 12, 2011 Report Share Posted June 12, 2011 Anything impaticulaur? Motor mounts and fuel pump look right and the dizzy position is in the middle right side like im used to. So everything is typical and obvious A series huh? Just an un-marked block? Maybe it was a fluke. 1 Quote Link to comment
RedBanner Posted June 12, 2011 Author Report Share Posted June 12, 2011 I imagine id have to check bore amd stroke to find out Quote Link to comment
RedBanner Posted June 12, 2011 Author Report Share Posted June 12, 2011 So if it dont run ill tare it down and check it out Quote Link to comment
metalmonkey47 Posted June 12, 2011 Report Share Posted June 12, 2011 Pull the valve cover and see what the casting number is on the head under the rocker shaft. That'll tell us what engine the head is from. It's a good start until all the smart guys get back from Canby Quote Link to comment
RedBanner Posted June 12, 2011 Author Report Share Posted June 12, 2011 I pulled the valve cover off first thing this morning and..... Also no casting wtf, ive seen unmarked heads before does that make it a specific one or did they just not mark some? Quote Link to comment
metalmonkey47 Posted June 12, 2011 Report Share Posted June 12, 2011 All should have a casting. But so should engine blocks.... I think it should be cast under the rocker tower on the first two cylinders somewhere, but no marking?? Quote Link to comment

Yeah I know where to look but its not marked, ive seen that 3 other times on what I think are the cali emissions heads..... Says that some of them arnt marked on 1200.com. Ima put a webber on it and turn it over. Has compresion and spark but the carb was full of dirt clods Quote Link to comment
Master-O-Turbonics Posted June 13, 2011 Report Share Posted June 13, 2011 Crate motor maybe? 1 Quote Link to comment
DRIVEN Posted June 13, 2011 Report Share Posted June 13, 2011 If you could ID the head to get a chamber cc, you could put a cylinder at TDC and pour a measured amount of oil into the spark plug hole. Subtract the combustion chamber volume, multiply X4 and there is your engine displacement. Make sense? 2 Quote Link to comment
RedBanner Posted June 13, 2011 Author Report Share Posted June 13, 2011 Damn! Thats good thinking, im reading up on 1200 tring to find that post again is a bicherdoodle Quote Link to comment

RedBanner Posted June 15, 2011 Author Report Share Posted June 15, 2011 You are looking in the wrong place! Ive got three others like this And the one in question, zillz is that a right hand drive car and would that make a dif? Ive scoured the block, using your pic wich is what I expected to see motor mounts are 1.4 so im gana assume thats it untill I find out otherwise, I toook these pics of the rear passenger side of my block Quote Link to comment
RedBanner Posted June 15, 2011 Author Report Share Posted June 15, 2011 where is the right place if I still have it wrong I meen, thanks zilla Quote Link to comment
Dguy210 Posted June 15, 2011 Report Share Posted June 15, 2011 Check on the other side of the engine, some models have an A14 as part of the casting itself (raised letters on the block between cylinders 1 and 2 I believe). I'll try and get a pic when I get home. 1 Quote Link to comment

ggzilla Posted June 15, 2011 Report Share Posted June 15, 2011 Well it is not so easy. There were several different A14 block castings, and at least two places for the numbers. * A14 cast on pad above fuel pump OR * or no cast A14, only the stamped numbers The most simple explanation is that someone ground the numbers away when they swapped the engine. Another explanation is that your photos are blurry so we cannot see the numbers but they are still there. You can fix that by holding the camera farther away. RHD and LHD cars have the same engine blocks. 1 Quote Link to comment
RedBanner Posted June 15, 2011 Author Report Share Posted June 15, 2011 Sorry bout the blurry pics, only" camera I have is on my phone ill get a couple more, but I woudnt lie about the lack of numbers, I mean how would that help? Scouts honor, I havnt found a casting on the block, or a stamp where it should be, yes the pics suck but you can see the othe stamps right, or does it look way better on my phone?

ggzilla Posted June 15, 2011 Report Share Posted June 15, 2011 No worries. Cell phone camera is OK if you hold it the recommended distance from the subject. Most can't do closeups but have fixed focus instead of autofocus. I see two possibilities: 1. Someone ground them off 2. The factory forget to stamp it Both seem unlikely but there it is. Can anyone think of other reasons? Quote Link to comment
wayno Posted June 16, 2011 Report Share Posted June 16, 2011 I went to a wrecking yard several years ago looking for an A15 block, they brought out a block and loaded it in the truck, I got it home and started cleaning it up and found the same thing, a pristine unstamped block, Dan Hart and I looked it over for a little while and he said that he had an A15 for this price and I should take this one back as it was more than likely an A14. The wrecking yard said it came out of a wagon, but gave me my money back. Quote Link to comment
ggzilla Posted June 16, 2011 Report Share Posted June 16, 2011 Learn something new every day. Hopefully it wasn't a SE asia knockoff of an genuine Nissan engine :P They still make the A15, it is used in the 2010 Nissan Serena. The engines are still made by Aichi Machine. A15 uses the second A14 block casting (so differs from early A14s which have 'A14' cast in them). So without the stamp you can't easily tell if it's an A15 or A14. Quote Link to comment
