It's not difficult to raise the engine up. An average person can lift the engine up, maybe not carry it but it's quite light.


Quote:Yes, it'll work OK, as will the 1981 camshaft. The GX spec is a long-duration cam than either. So it all depends on how high you want to rev the engine. I'd recommend a GX cam if you have 4.11 or 4.2 gearing (which allows easy 75 mph crusing), a lesser cam with taller gearing (e.g. 3.7 to 3.9).

I have a 3.9. So a lesser cam then for my application. Do I have the 81 camshaft grinded or purchase a new one?

The 1981 camshaft is already a "lesser" cam -- it has less duration and less power than a standard A14/A15 cam

It's a bit of a package deal. If you want to go with less revving, go with less cam and smaller-port cylinder head. On the other hand, if you want to rev to 6400 RPM use the parts designed for high-power, high-revving -- a GX-type camshaft, GX-size cylinder head and GX-size carburetors (either twin 38mm SU-type carbs or twin 40mm weber/mikuni/dellorto, or at least a weber 32/36)

If you were to fit a less-duration cam with the GX head, it's like shooting yourself in the foot. The cam isn't big enought to make good HP at the top end, yet the GX cylinder head is too big for maximum torque at lower RPMS

For maximum power, use the GX head, and rev it up high. Steep gearing will help to rev fast. 4.2 is what I'd use for all-around street/highway driving. Even steeper gears will accelerate faster, but at some point it starts to limit top speed and/or overpowers the tires.

Many of use want more relaxed driving. Using 3.9 gears (which were stock on most Datsuns with A-engines) mean less shifting, less noise, higher fuel economy and slower acceleration. I had two 1200s
* Stock A12 with 3.9 gears, it was a relaxed enjoyable driving experience
* Built A14 with 4.1 gears, it was an exciting, tense driving experience

sorry edited my post, it should say A14 fwd sump has the bumps to suit a15 crankshafts a supposed option somewhere on earth?

FWD sump has longer front hump section welded on, this extended hump
is easy to cut where its welded and weld on a winged section on it.

Ok. I recall seeing a datsun fwd car in this same salvage yard. It did have the A14 engine in it but dont recall the specific model. When I make it back out there, will check out the oil pan and see if its better than the rwd b210 car. Or may just end up getting both.

Hey, G.

That 262° duration, .425 lift (at valve, I think). cam in my build, a regrind from Delta, has worked out great. Larger than a GX (A12GX: 256°, .331 lift at cam), it has very good torque all the way down at 1500 and a wide power band that allows me to easily cruise in 3rd or 4th in the windy canyon & mountain roads I love to drive. It is amazing the tractability of this engine down low. Of course, it moves well when I put the spurs to it. Stock valve springs limits my Rs, as I have not yet swapped in the GX spring set I recently purchased. Now, I am still using the stock Midget mufflers. Replacing those with something more open will change the tourque curve somewhat. Still, if building another A series I would use that grind again. On the other hand Delta might be able to reproduce a GX on your core, or another profile.

Here's a FWD pan for A14

This FWD pan looks like it will work with A15 (Datsun N10 "310" pan)

Hey Tom thanks for the cam information. You have a GX head with your A15 as well along with the 3.9 diff? Cant keep up with everyone's A series rebuild projects. Hope you like my lengthy thread here. Lots of good information. Really anxious to get on with my project, but now with travel coming up and the holidays it may be a few more weeks. Have most of my parts but need to go back to the salvage yard for an oil pan(s). I am looking at notching my oil pan vs cutting into the structural crossmember. Kurt says the B210 pan is better suited for that since its a mid sump (less invasive) but according to DD, I need to put a hammer to it to clear the crankshaft. I will let my fabrication guy determine what is best. Cool looking road you got out west in California. I am jealous!! Here in Texas we have the hill country which is south west of Fort Worth, but no comparison. Catch you later.

DD thanks for the pics. That is quite an oil pan on the fwd car. D was saying it is easy to cut the extended sump and weld back a wing. As I previously mentioned, will let the guy doing my work figure out the best solution. I can get datsun parts fairly cheap from this salvage yard so will keep accumulating whatever parts may come into use.

Do you know club member John Roper, the 1200 guru in Fort Worth? He might have parts or ideas.
