Side note - I REALLY hate how the posting of pic's is done on this site. Using Photobucket for years for off site storage but there's no direct cut & paste from my computer storage or from a phone thats not 7 steps for posting pic's....that Im aware of.

There's got to be a better way......

is the URL post button above the only pic post option?

I know, Im whining - wah wah wah

So Im sh*tcanning my A15 thats been in the car since I built it (flattening cam lobe issues) built an early A12 "race" motor I had laying around - literally! and am looking at the engine mounts - looks to me to be a later crossmember with the LH short mount boss.

I know the RH side motor mount needs a longer plate to mate up to the bracket on the engine but what about the left side? It doesn't really look like it lines up , left side is the shorter boss on the Xmember. were the really early A12 Xmembers on the RH side canted towards the front of the car?

Also wondered if theres a SN breakdown to ID exact age of motor, cant find it in the Wiki..

Thoughts??

thanks!

swore I saw some rusty Datsun pickups on Maui back in Sept Dave! Why dont you buy that guys garage thats for sale in Makawao & start the Maui hot rod shop.

Wasn't attempting to discredit, apologies if thats how it came across - just saw it again trolling for Datsun stuff on CL. & was sharing the love :)

Maybe?? holler at the car lot to stop advertising your car or at lease say "SOLD" across the ad. Enjoy it, looked like a cool ride and other that Davids?? in Canada haven't ever seen one.

still available

thats just around the corner from me, saw it on craigslist but never went over to check it out. Enjoy it!those guys has some other cool cars too

Are you trying to find the static compression ratio of your engine build? If so my recent experience on my A12 proved the numbers in the wiki incorrect for CCing a cylinder head. A brand new NOS H72 head I have never milled, never on a motor, never built worked out to 41 cc’s .

I think the wiki says 25 to 30 mL so I found relying on that info completely inaccurate for figuring out the compression ratio of this motor. Best to physically see the piston in the block and the head individually.

As an example the H 72 head I’m using is 25 mL and it’s been milled substantially, to the point where I need to use index washers on the spark plugs to clearance the piston tops as they’re forged And actually stand above the deck.

Overall my point is just do it physically so you know with certainty what it is you’re putting together.

Good luck!

was the "Volts" one a digital display? it looks like the word volt is done in that old plastic tape with the raised white letters...

that is pretty cool, never seen one. Kind of works the same idea a bit differently. alter the fuel/air mix to tune but this way you get an actual visual real time aid vs. look at plug color after a certain RPM rev up. Kinda neat!

I’ll have to look at the casting #. either way mines at 41cc so the data is really far off, thought it was worth noting for others.

As far as “just fitting” a 4.6 ratio ring / pinion setup- those are like unobtainium & besides that who’d want a street car with that setup. I sold a 4:10 setup to a dude in England for like $400 about 8 years ago, he was ecstatic to pay that cuz he couldn’t find one.

When I get the motor back together I’ll check the dynamic compression #’s with the cam in , I can use the timing wheel for that, it’d be interesting to see what that works out to.

Thx all!
