A bit of Mopar History here for sale on Ebay THIS IS NOT MINE

Cool stuff! Incredibly strong but incredibly heavy Direct Connection "Hemi footprint" rods. FWIW, too bad the motor mount ears have been cut off.
 
Looks like a lot of old used up race parts . Most would be nice shelf items for a collector. The blocks look to be just standard blocks cut and shaved for weight. They are not race blocks . The mains are drilled off set due to lack of material the standard blocks have in the webs. It was common to use a standard blocks because the race blocks were almost twice as heavy with high nickle content.

The only thing I see worth anything would be the heads
 
it looks like the blocks are not std factory blocks as the 4-bolt mains usually have the outer bolts drilled at an angle. where the bolts are drilled is straight down and they look to be "beefy'. did TA blocks come that way. ONLY 11,500 per engine core!

Correct. You can’t use an offset angle bolt cap on a T/A or later race block, but you can’t use a straight bolt cap on a passenger car block.
 
I agree with Steve's assessment. "Used up". Those blocks have been ground the CRAP out of.
 
Surprised the blocks don't have the oil galley crossover tube modification...

Here are pictures of mine . They are not offset as the blocks pictured in the ad. Orange block is T/A- X the second is R3 - Resto. All 4 main studs are directly inline and parallel. The old way to put them on a standard web was to center the outer hole in the web where it is thick .. Check out the core plug location difference

Right. But you can use an offset bolt main cap on ANY small block. Just because those blocks are drilled for offset bolt main caps did mean they aren’t T/A or later over the counter blocks.

There isn’t nearly enough detail in the pictures to say one way or the other what blocks they are.

It’s hard for me to believe that at the level of racing the guy was doing he was getting away will flimsy passenger car blocks.
 
All race blocks were casted using the 318 mold and take the left side engine mount for the the 318. This relocates the core plug on the left side. I know the difference in race blocks to standard 340's

Believe me These are 340 blocks pictured in the ad. They are now junk and more then likely to max bore. Usually they were built for one life and then thrown out. If they were race blocks of any type they would have stated that. They just state the stage number of their machining of destruction.

That is why I stated above to check out the core plug location. Dead give away. Junk! Or I am sure my son would have been on them.

Does the T/A block have the 340 core pattern?

I can’t remember.

Yes. I used the 340 mounts on mine. But the webbing is the same as the X block. The X block uses the same oil filter adapter plate as a LA 340 318 273 also. The R3 and Resto use the newer magnum adapter plate.

The resto has the 340 part number and 340 cast in the block to use in stock class. They also cut the 16 outside and inside head bolt bosses off so only 10 can be used. Lifter valley is totally different on the latest resto and was designed for a 48 degree cam shaft. Strut style Tall roller lifters can be use with severe block modification to clear the lifter strut. Or Key the lifter bore. Note the head bolt holes not used because they were cut out of the block.

So they could be T/A blocks.

The T/A block I had came with offset bolt caps. IIRC the guy that I bought it from said those were the only 4 bolt caps at the time. And they were made so they would fit on passenger car blocks.

There weren’t many T/A blocks around even then.

I know he put the engine together in 1974 or 1975. I think it was for Modified Production. He had a set of fully ported T/A castings he used before the W2 came out.

He quit racing when NHRA killed Modified Eliminator. He hated bracket racing.

I agree with you in that even if they are T/A blocks they are used up.

The heads and valve gear is worth something if you don’t mind iron heads

I didn’t see them but if they have a set of W2 stack injectors that would be cool.

Although there is about zero market for a stack injected W2 engine.

Edit: and they machined the oil filter pad off. So at best you’ll be running a remote filter but it looks like they plugged the feed hole from the cap to the block permanently.

That means dry sump only unless you can undo and unplug whatever else they did to run the dry sump.

My T/A block had the same main webbing as the X-block. It was just not drilled for the 4 bolt center three caps . Look at the front of the block down by the main cap in the first picture and compare it to the second picture. All T/A's and X blocks I have had were like the second picture

Also the x block was almost twice the weight of a standard block due to high nickle content in the iron. And also still heavier then the just as thick T/A

It's a bummer there's not more numbers on these parts.

I have dyno and head flow sheets for the 74-75 Shadow Cam Am/F5000 motors. Directly from Bob Tarozzi who ran the motor program.

Bob is who led Paul Rossi to buy this stuff who then sold to current owner. Paul was not part of Can Am program so there really isn't any first hand knowledge there.

These motors most likely were NOT from the CamAm cars, as big block Chevys are in them. Think these are from the F5000 Shadow DN6/B cars, which is basically the DN5 F1 car with a small block in it mounted to the Hewland TL200 gear box. There was 4 CanAm cars: AVS, MK2, DN2 and the DN4. All were naturally ansp injected other than the DN2 is turbo charged big block pushing 1000 HP in 72 on race gas which is crazy for the time. It was running last summer.

As for the parts, it’s kinda high as you would be taking quite the chance. There is only a few people out there that have shadow F5000 cars and it could be worth something to them to restore or fix a car, but outside of that, the F5000 owners are cheap as f**k and won’t spend the money on the car, as they are not worth anywhere close to what an F1 car is worth.

Used in the 1977 "Can Am" season that yes were based on F5000 chassis.

World Sports Racing Prototypes - Can-Am 1977
12.00Randy Lewis (USA)Shadow DN4B DodgePhoenix Racing36-5.1:40,597

Phoenix Engineering was Bob Tarozzi's business. That shop used one of two dyno cells was rented space from .... Shadow race cars.

Again there was a lot of other developmental stuff being worked on at the same time at the same shop. So some of these parts could be F5000 and Can-Am parts or other developmental projects.... or both.

But a dry sump block would most likely be a Shadow race car or Nascar cup motor.

And those cars are gentleman raced now. So a lighter, shaved down, tweaked out block isn't a big deal to them. Reliability for lesser cost, safety, and breakage is more important.

I also doubt they are pumping those motors to measure cubic inches.. so if they ran a larger 340 at a lower rpm and similar HP that would save them money.
