Thanks Leosnake,
I just got off the phone with Steve. He no longer does much with A-15's. He reccomended Hank at HP engineering in Rhode Island. Ph# 401-789-6700.

myko2,
Are you sure yo need duals?

I just got done dealing with valvesprings for my 1608. Last year I bought one of the last Crane cams for the A-series engines from Crane, on a close-out sale. I got a brand new F-22/280-2-10-NC cam for $55!
This cam has [In] .420" and [Ex] .441" of lift. This week I finally am ready to assemble the head and needed the proper springs. The recomended springs are discontinued throught Crane. They were part# 902-0002 and are a single spring rated at 80 lbs. closed at 1.531" installed height, and 209 lbs. at 1.131".

In any case, I scoured the Isky catalog and ordered a set of their JA-006 inner springs to add to my stock outers, measured them together with my spring tester- no good, not enough pressure.

Next, I got out my extra set of Nissan Motorsport competition dual springs with aluminum retainers. These were far too stiff for my Crane cam.

Finally, I did a google search for the correct Crane springs [the 902-0002's] and was really lucky to find them here: http://www.aptfast.com/ It turns out that this firm primarily deals with the "other" A-series engine, the British ones. Just by chance, they use the same valvespring sizes as the Datsun A-series.

It turns out that they have two sets left, so I bought one of them this morning for $58.81 + $6 UPS shipping. BTW, they initially thought they didn't have them, only to later realize that they had renumbered the part number recently to S-002-8. I was really lucky to find them and now there is only one set left. How much lift is your cam? If even these single Crane springs aren't enough for your cam, you could always add the Isky inners and that should do it.

Wow!! Thanks for that info. What a coincidence. I have been dealing with David Anton at APT for about 10 years. He builds my race heads for my Mini Coopers. Does an amazing job too. I just got off the phone with his assistant. I bought the other set. In talking with her she mentioned my set has the instructions, and yours didn't. She made a copy for you so call her with your fax number and she'll fax em to you.
I asked what other parts they have for the A series motors but David is out of town until the end of the month, and no one there knows. I will call David when he gets back in town.
His number is 800-278-3278 (800-APT-FAST).

Great!

Don't you love it when a plan comes together?

I wouldn't be too surprised if there isn't another set left in the US now.

I don't have a fax number, maybe I can get her to send me the copy snail mail.

What lift is your cam anyway?

Thanks

Not sure on the lift of my cam. I had it ground to TR-3 stage 2 specs. Pulls nicely from 1500 to about 6000.

Plenty of sets here in OZ at $80 AUD ($56.8 US approx) a set plus postage.

Got my springs today from APT. They look excellent. They are the Crane Cams ones. Total came to about $60US for springs and shipping. I will install them this weekend. Thanks again to BlownB210

You're welcome. Hey you got your springs before I did. Must have something to do with living 3,000 miles closer to the dealer.
