Can you tell / decode

You want rpm play with rotary engines. I used to shift my old 74 at 9000 lol

Hell, what was wrong with it it would only do 9k? when I was fukking around with the Hondas' you could spin the 1.6 twin cams to 10k all day long with heavier valve springs. With indy car springs, you could run it all the way to 12k before the shift.

All the internal seals were wasted from sitting for like 15 years lol

lol, I though they ran the fastest right before they **** the bed?

It still ran it just smoked like Whitney Houston.

So I climbed up there and the number I saw was 8970010 but it' dirty and pretty sure the 8 is a 3. So 3970010.

A '70 B-body with a 4-speed would have been super duper rare. Iirc, a 4-speed wasn't even available after the '69 model year. At least not available to John Q Public.

Lol. There's some truth right there....

Just going on what the book said... The note next to CNP said 350-2 Police / Taxi MT. I can't see Police or TAXI drivers using manual transmissions but manuals were common and cheap in 1970 so... ??

People claim there's no such thing as a 1969 Mopar C-Body with a manual. I robbed the floor hump, pedals, and linkage that are now in my 1969 Polara 500 from a destroyed 1969 4 door Fury. A friend found the Fury in 1983 when I was building my 4 door Polara high school sleeper that I unfortunately shortly wrecked. I kept the parts because I knew they were rare and I re-used em when I found the '69 Polara 500 shell in 2002. No need to worry about numbers matching when there's no original engine and transmission. That boat is a blast to drive.

It's just the 4spd that I didn't remember as being available at all. There were still the 3 spd cars. I need to go do some reading and refresh my memory. It shames me that there's full-sized Chevy facts and figures that I no longer remember, lol.

Three on the tree is certainly a manual transmission.

It does say 4 spd tho... and those are B-Bodies.

CNP 1970 350 4 spd, pol/taxi - 250HP 2BBL Caprice/Bel Air/Kingswd

The one with real Zip to it is the CNR

CNR 1970 350 tur hydro trans - 300HP 4BBL Caprice/Bel Air/Kingswd

Kind of a mystery without pulling the casting number off the block.
If it turns out to be a 350 block and not a 307 you'd need the number off the camshaft and or the heads to actually ID the thing. If it has a 1970 4bbl or 2bbl GM intake that would get you closer too.

Yep, it sure does say it and I'm sure I'm wrong about the lack of availability. But I'm still going with super duper rare. ( Please note, I do not mean to imply rare means valuable or necessarily desirable here)

 

[Croc1990]

The casting number on the back of thr block is 3970010

 

[bucket]

I would be willing to bet it's a 1970 307 someone was trying to pass off as a 350...

The 307 is a 283 with a 327 crank. Shorter stroke and larger bore than a 305. Not a bad motor actually. It has a fair amount of low end torque making it a pretty decent small V8 truck engine.

What's the block casting number behind the LH cylinder head? That should narrow down the displacement.

Is the block drilled and tapped for the Clutch Z-Bar pivot ball? Not definitive but if it's an un-molested 307 with those stamped numbers it prolly won't have the hole.

I got curious about mine after you said this. Mine is CNV which is 350 w/2bbl and th350. The block is drilled and tapped for the ball stud.

 

[hatzie]

It only helps ID things one way.
A lot of the smallblocks that were bolted to auto transmissions were drilled and tapped for the ball stud.
If it didn't have the ball stud hole machined it definitely came from an auto trans vehicle but if it is machined it doesn't tell you what you want to know.

That's why I said it's not definitive...
