I’m a Datsun newbie! Always wanted a 240z/510 project and finally made it happen over the weekend. I picked up the 73 Datsun 250 miles away from home with the “guaranteed to make the drive” from the owner – which it did not but we’ll get to that later.
1973 Datsun with a SBF 306 engine with GT40p heads, single plane intake, 750 Holley HP carb, speedway headers, 3” exhaust, manual valve-body c-4 transmission with SFI bell housing and 9” stall converter, TCI shifter, R200 posi rear end, Meziere water pump. I realize the 750 carb is probably too big, I think its what the PO had around and tuned it work. Motor seems to run strong, starts up pretty easily from a cold start and sounds like a beast. I however am a complete V8 newbie.
Here are some pics of the car/engine.

I ended up having to tow the car after 40 miles of driving as smoke started to fill the cab, when I pulled over it seemed like transmission fluid was dripping onto the exhaust. Upon examination we found the speedometer (speedometer and tach not hooked up) cable opening was closed with a rubber bushing and a wingnut. I tightened up the wingnut and have taken it for some very short trips and it has not leaked yet. So that either fixed the problem, or when the fluid gets hot it begins to leak (I think I read something about a overflow on the top of the C4.)
So I am working that out. Problem is – I am not a huge auto guy and would prefer a 5-speed. I don’t even know where to start with wrapping my head around what that would entail.
I have 2 large questions at the moment. The first is the transmission which has no transmission cooler – and it not hooked up to the radiator for cooling – is this a problem?
The second is the flywheel – it looks like casing was trimmed back for some reason and the flywheel is exposed – is this a problem?

Thanks for any help.
