74 3.0CS (3.5L) on BaT

[autokunst]

I thought there was a thread about this one already, but I can't find it. Does anyone else feel this one is not getting a lot of exposure on BaT? I've had to search for the auction listing several times. It seems other recent coupes were right up at the top of the list in the larger format for more to see. I guess that the order of displays might have something to do with view and click algorithms - so it might not be a conspiracy.

Sharp car. Would like to see the bids increase - it has been stuck at $50k for a while. Ends on Monday.

There it is - hiding in plain sight.

The bidding has plateaue’d and will fire up again in three days. I’m in love with that engine. @Sven - I have cam sensor questions for you.

 

[HB Chris]

It’s on their banner at the top of BaT.

 

[Sven]

ask away - cam sensors

Thanks Sven! I was just wondering where you installed the sensor, and what sensor you used. I’ve seen setups that leverage the distributor area for the sensor, but you still have the distributor in this car.

I’m absolutely in love with Michael’s car, particularly the motor.

On the b35 head the sensor is tapped into the upper timing cover pointed at a small tab/pin brazed onto the adjustable cam sprocket. On the older style b30 head front cover I have a small pin near the end of the cam shaft (or maybe in the little gear thing that normally drives the distributor).

Is it a Cherry hall sensor.

At $65k with 21 hours to the finish line. Getting interesting.

Thank you sir! The EMS that I will be using only supports 4cyl sequential, it isn’t a priority. I just wanted to understand the tech. I didn’t realize that the B35 has a hall sensor.

Yes, I saw that there have been some aggressive bids over the weekend. It sure is a beautiful car. I wish the seller good luck with the auction.

i am curious why the engine has a b35 head on a 10:1 b34. my understanding is that head will cost lower the compression of a 10:1 b34 block. i do get the better springs / valves in the b35

 

[rsporsche]

68k w/ 15 hours to go. i expect this to take some big jumps in about 14 hours. i am predicting 80k+

Try this- b34 block with b35 pistons and head.

 

[Markos]

Try this- b34 block with b35 pistons and head.

So a true 10:1 compression ratio with the B35 head.

 

[sfdon]

Correct

 

[HB Chris]

$125K! Another benchmark public sale and well deserved.

 

[Markos]

That was exciting? I'm wondering why it went up to $125K then back down to $107K. Not sure how BAT works...

 

[Markos]

Ok nevermind, I swear this auction broke my browser. Getting very funky caching issues and flip flopping of information.

 

[Markos]

Strange - it says $107K on my laptop (even after clearing the cache), and $125K on my phone.
