Well, you can be the judge of it for yourself. But when a guy is willing to pay $1200 for a Datsun 510 tachometer... I'm out. Or $600 for a 1969-70 Series 1 240z ash tray? No thanks! A few weeks back an acquaintance's 510 wagon sold on Bring a Trailer for over $30,000 ... It was mismatched red panels. I miss the days when you could actually get paid for hauling away a junk Datsun. Or when a Z was about $10K fully restored. Some Z sold for $300K a while back. It's all nonsense. It was far more fun when it was cheap. At least with American stuff it's loud, rumbling and "actually" fast. There's nothing fast about a 1.6L Datsun 510 with a 2 bbl Weber. I actually sold all my Datsun and made about $8,000 on B210 parts. ... Yeah, say that out loud! Eight-thousand dollars on B210 parts. Yikes. Made enough money to buy this Barracuda and still have some left over. Wild world we're living in.

But that's like, my opinion man.

I had a slam rusted out 69 date coded 70 240Z. Car had all original drive train and ran and drove. Quite reliably, I might add. I had a guy drive from Oklahoma to Macon, Georgia to give me 9500 dollars for that car. I gave 600 for it and got it running. It needed everything. Floors, quarters, fenders, it's one saving grace body wise was the 70 only hatchback door with the vents was perfect. That's one of the few cars I ever actually made really good on.

The early 8 bolt stuff was 1018 and when Scat got the MP contract everything was 4340. I’m not sure MP ever offered a crank in 5140 but I’m not sure on that.

I thought I read 5140. I could be wrong, IDK. Feeling lazy at the moment to get up and check….
:lol:

But the crank is a forged 8 bolt unit.
It sucks I won’t get to it for a while. To much on the plate to worry about what I’m going to mess with next in the storage closet of parts.

Screw it, I’m getting up. It’s on the way to the coffee pot….
 
OK, I got coffee and checked.
Book said 1053.
I was told this is not as strong as other cranks. I don’t remember off the top of my head the pecking order of the number designation. It doesn’t matter much to me now since I have no idea how I’ll use the crank.

Yeah, I think 1053 is the material used on the OE cranks and the 1018 was what the “Kellogg” 8 bolts were made of. What book did you find that in?

What about around 1977 to 1979 what material was used ?
Mine is a 3.20 stroke 8 bolt flange Bob Glidden crank I guess he used Mopar Stock but mine had chroming process installed which I was told was very expensive back in day ??

That should be 1018. I don’t think I have a cat along that old but I think I have a 1982 catalog. I’ll check and see what it says.

LMAO! I gave away all of my older catalogs to new MoPar guys up and coming. My oldest one is a ‘96.
 
That’s true and there abandonment of one engine family after another, the small block is the latest casualty, really sucks. There used to be big support. The pricing was rough. I was unamused at the Chrysler mark up when you knew who’s parts they were. But at the very least, they had it and you knew where you could get it. Even better when the truck showed up at the race track and you needed something fast.

Well atleast we lived when the
LA
B & RB and Hemi
Were popular ###

Yesterday when I picked my engine up Hensley had two new alum
Aftermarket Late model Hemi blocks
That if I remember correctly he said will approach 450 inch he said those are getting very popular I guess just like the LS Chebby motor ??
Heck those new Hemi heads (oem) flow over 300 cfm stock correct ?
I can see why its the engine of choice for a younger Mopar guy.

I don’t know what they flow stock. On moparts, search Brett Miller for his HEMI head work.

I believe its common knowledge in stock form either 300 or around 300 .
Oem cyl head technology has improved without a doubt with the modern engine
And the LS and late model Hemi
Are KINGS for the future
Aftermarket parts galore.

Wow ! You can see why the Hellcat makes so much power with a little boost !
 
Seriously, I dont know why people still build older platforms (present company included!) for power when these ARE IN JUNKYARDS NOW. LS took over the small block world, and these are gonna run the LA/Magnum crowd slim too.

Well personally I like to keep the stock look under the hood and I enjoy the nostalgia feel . Which is why I think the FAST and Pure Stock classes of racing are the coolest.
If I was building a pure race car I would consider a Gen 3 .

Hopefully u are correct ##
Tractor pulling and restoring used to be the same way now its dying out also
Think about it
30 or 40 years ago we probably had 20 US tractor manufacturers
Allis Chambers
Minneapolis Moline
Oliver
Cockshut
JD
Case
Farmall
International
Etc etc etc
Now
All are gone and or made in other countries
I have a Modern Massey Ferguson and the dam thing was made by a man wearing practically a dress over in India ( WTH )
All plastic and ( FRA-GIL-E) everything cost more and is disposable today.
