What's that black sealant on the case halves?
-Chris |
Chris,
The sealant from the garage, I will ask tomorrow phe |
Great Images Phe - Keep em coming.
Have you rebuilt the heads yet? |
Great pictures. The black sealant is worrying me. I don't see any assembly lube on the rod assembly. Maybe it is just not in the pictures.

On the subject of EFI vs Carbs-- I would say the level of difficulty and time involved for the two are the same up to the limit of the carbs ability of performance, not counting any pollution control considerations. Both take a dyno or many hours of track time to get tuned in over the enitre rpm range. But the power band vs AF ratie is very very forgiving, so carabs perform quite well in this reguard.
I would like to add that if you are really going to get everything that EFI has to offer you must also change the combustion chamber design, the piston and ring design, the intake and exhaust and several other things. You will not get year 2000 perfromance out of a 1970- 80 something engine, no matter how long you play with the EFI. You probably will gain a lot in terms of pollution control but not performance. I wish you could. I am an electrical engineer and would love to be able to tweek one of these older engines, but I cannot find a workable solution without redesigning the whole engine. You can probably do better with a chevy because they are water cooled and since you have to have aftermarket heads anyway ( nothing chevy makes is real usefull, except the block) and can bore them to the precise dimensions required by a modern engine, and can buy newer pistons with the correct ring size and placement...ect |
Wow, sounds like Jack is reading my book!
:) -Wayne |
Wayne, sorry but Jack is not reading your book, he has a good experience, but I am reading it for him...
The black sealant is from airplane research technology, this is one of the little secrets of Jack the mechanic. This sealant resists better than normal, but it comes from a black factory from a secret lab from nowhere.... Phe |
Forgotten pics.

phe,
Has you mechanic done many 911 motors? I don't want to alarm you unnecessarily, but the lack of a 911 engine stand, mystery black sealant, and a rather dirty work area is setting off warning bells in my head... -Chris |
Do not worry, the engine stand is coming now.
I fully trust the mecanics, I have seen engines rebuild by him, they are running strong and the reliability is really good for track and street. I am not going there as a blind man. If you had the possibility to use aerospatial sealent, you would, guess I correctly? I just cannot say where it comes from because this is not official. phe |

Phe,
I didn't see any angles where there was assembly lube on the bearing surfaces of the crank and Rods. I'm sure it's a basic step that any mechanic knows, but they DID use it right? |

Phe
you state at the beginning of this post that you have 3.2 conversion kit. Is the kit from a European supplier and if so could I ask where from and perhaps how much they cost. I have an associate who has told me that they can be purchased for £1800 (approx 2,010euros) + carriage cheers Tom |
Hi there,
I think that remarks has been done enough according to this engine rebuilt. I'd like to talk about the EFI vs Carbs discussion concerning SC engines, but I think this isn't the aim of this current thread; let's create a new one ? Regards, L |
Tom,
I purchase mine from a reseller of www.fvd.de, the cost was a little more than what you said 2750€ HT. Think fvd is selling in US, UK , Japan,.... phe |
Phe,
What I was saying is that I couldn't see any assembly lube used on the bearing surfaces in your pictures posted here. |
Chris you killed me last night, I had really really bad sleep.
There was assembly lube. I do not send every picture I have. Thanks a lot. I feel better now. Philippe |
Sorry buddy, I'm just the paranoid type when it comes to motors. Sorry to heap more worries onto your existing pile! :D

While you have the seats out you should put in the eye bolts for your sub strap belts.
-Chris |
I do not have them yet, we have done a swith for larger belts.
I will receive that in a few days. phe |

Hi Phe,
Well this engine will be soon in the car ! I have few remarks : Do you use original valves ? It would have been a good idea to machin them, reducing the angle radius : this helps tork at middle ranges. The ports should also have been cleaned. Did you also check the springs' strength ? One more important thing : don't forget to check the chamber volume and piston clearence for each cylinder ! I think it's non-sens to lose some time lighting and equilibrating rods if this basic work haven't been done. Regards, Luc |
Luc(snoopy),
valves: 50%new 50% old but checked (for machining too late).Must stay a road car (about 60.000km/year!) springs: all new. ports: agree, it looks dirty (I will drop a call) clearance: schedulled. phe |
re Phe !
>Must stay a road car (about 60.000km/year!) This is always my goal to keep an engine reliable. Machining valve just helps flow at low valve lift and never affect reliablity. >springs: all new. Good. Bought all together ? >ports: agree, it looks dirty This is not important. Never polish the ports, it's lost time. But the moulding lines should be removed. It should have been done if the valves, seats and guides were done. So keep them like this, 3.4 engines work enough don't they :) ? And let's consider you will have a good air/fuel mixture thanks to it ;) ps. Snoopy is already used by another one on this forum :( Luc. |
Finished (I am getting closer.....)

I know you dont like to do that so (Merci pour l'effort) phe |
:)
Now you *just* have to check for the volume of each combustion chamber. Also don't forget to compare piston heights. A good trick : if you need to remove material to set the biggest volume you measure to all chambers, remove it around the spark plug. This helps combustion and reduce detonation risk. Have fun ;) Luc. |
Nice pictures! I just love to watch rebuild in progress.
I have one idea: if you are going to assemble the heads with plugs already mounted, why not use the oportunity when you can see the plugs "from inside" and index them, to get every last horsepower drop? :) |
Quote:
-Chris |
Indexing the plug doesn't matter if you don't have a per-cylinder compensation (that means advanced sequantial EFI with one temp sensor per head). It's really more important to calibrate injectors (or fuel distributor) and be sure to get the same compression ratio for each cylinder.
