I would describe it as "a honking big profile"

270 duration. I had 278 in my A15 years ago. Would rev. To 8500 rpms.

LU84N Electramotive 04 7251

Electromotive was a prominent Datsun racing company which supplied cams to Datsun Competition

A-13-1 may indicate the 13th cam profile for the A-series race engine?

84 suggests 8400 rpm
* Nissan Competition 74 was 7400 rpm, 296°
* Nissan Competition 80 was 8000 rpm, 320°
* Nissan Competition 82 was 328°

Note that a stock A12 engine will rev to 8000 rpm if heavy valve springs are fitted. That's with the stock 248° cam.

Nissan Comp gave the normal RPMs, e.g. max HP at 8000 rpm with the 80 cam. With the stock A12 cam max HP is 6000 rpm, and far far less at 8000 rpm.

Well, short history, the engine is a A14 with arias pistons 1,430cc, with a special big ports by Slovers with standard conrods and electromotive crankshaft preparation and this ELECTRAMOTIVE cam comes with the pakage, the second cam CRANE is a gift. This engine in 1984 win a cup in my country.. after many years come to my hands just parts from the complete engine without carbs and manifold. and we my father made a new vintage car. Here are some pics, and next i want to share the process, to you my friends. i have a lot of work to do but is on the way.
we found a special manifold for a great friend and Webber 45mm
the car has 2 races. the next in march. any comment are welcome !

¡Que bonito!

Crane Cams F270/3732-4 BH4525

F = Flat tappet (mechanical lifter)
270 = 270 degree at .050" lift
3732 = 0.3732 inch lift at cam (9.48 mm)

Compare to the Nissan Competition cams:
• 13001-H5700 256°, lift 8.4 [redline @ 6400 rpm, requires dual valve springs]
• 13001-H5710 280°, lift 9.4, normal RPM 7200, recommended for rallies

Definitely a FWD Engine with the deep Alloy Sump and those headers.

What a great piece of history having such an engine. It seems some of the highest performing A-series engines of that era were featured in FWD Datsuns.

Are you the person who has just downloaded my catalogues? Hope you enjoy them and they come into good use.
