@Bahnburner My engine builder reports that the threads in the case were ok and Timecerts were not needed.
You can call him directly at the number on his invoice.
Did the shop install time-certs into the block for the head studs? Or are you using the original threads with the dilivar studs?

My research on this motor and according to the red spec book by Paternie and Bodensteiner indicate that this is an engine type 911/92 with a compression ratio of 8.01 producing 150 hp.
The 175 hp engine is a type 911/93 with a compression ratio of 8.5:1 and has engine serial numbers starting with 634———-. To the best of our knowledge, this is a stock 911 engine. If you want to ask about specifics, contact me directly. I’m sure power of this engine could be increased by changing exhaust, fuel induction and camshaft grind.
Does anyone know the difference between the s motor in 74 and the non-s? I thought they were dyno tested and categorized, but that seems odd to me. My point is if they are really the same might this engine produce more than 150 hp? Seems like intake and exhaust would be big indeterminates here.

This engine was built to stock specifications for a 1974 engine. The horsepower rating was 150 horsepower.
The builder warranty is to repair the engine should it fail due to workmanship or failed parts.
The builder will inspect the engine to determine the cause of failure, ie. overrev, lack of lubricant, failure of parts etc. Repairs will be made depending on the cause of the failure. The warranty does not cover drivability problems related to carburation or fuel injection problems since those systems are not included with the engine.The warranty does not cover racing use. The engine builder is
an incredibly fair person and has a great reputation in this area of the country.

I should have stated that the 1974 911 engines started with 6140001.
You are correct that some of the earlier engines had higher serial numbers.
Thanks for your comment.
My research and from Stoddard’s listing indicates that this an early 1974 engine.
I believe the engine numbers for a 911 started with 614 0001.
I could be wrong, but I think this correct.
Is that serial number from a car earlier than 1974. My 1972 E has the first three digits starting with 622?
