"Someone" once told me if you're making stuff you're breaking stuff. No matter how many times you measure, there's always going to be hiccups.

Tonight went a little better. A little RTV and the world is a better place.

this is getting exciting. a work of art.

Soon the 599 replacement will be announced,it looks like it will be down on HP compared to" V12 conversion begins"......If you cant beat them join them,Hey,Butcher,the weather in Modena is better than in Penn....Piero,I know your reading this,here's The Man.....FORZA,,,,,,porky down

[duck.co.za]

That's a HUGE milestone Well done Mark , congrats

+1: Must say, even with all your expertise, that now, it's getting to a point I can better see.


too soon, but can't wait to hear the youtube sounds

Mark- Congrats, she is looking really good. Hopefully the ECU and everything else will come together at just the correct time.

R- Those pigs are getting to be a real nuisance and are moving west. A farmer in Clovis, NM has killed 300 in his fields so far.

Dont feel bad about using rtv silicone. All the new yokes rely on it heavily.

Did you do any preflush to the oilways or are you just going to let the sump and filter catch the bits?
I guess its the filter to journals ways that matter the most.

Looks great, you HAVE to be getting a little nervous at this point, are_you?

Brian!

I have a motec M800 back-up ecu so when the engine is ready, that won't be a hold up. It can only run 12 injectors but I'd like to see what the low set vs the high set does hp wise anyway and I can transfer any tuning I do with the motec to the new ecu without more trouble I think.

I'm still leaning toward tryting to do the break-in and tuning on a dyno...when the time comes that is.

[ferraripilot]

Brilliant stuff Mark. It's like a modern day Muira engine, only cooler.

I actually think the RTV will do a BETTER job sealing than the OEM solution. While I was looking at it I decided that the rear main seal mounted on the back of the bearing cap that was dry set on the block was pretty much guaranteed to leak so I popped off the ream main cap and put a VERY thin coat of aviation sealant on it (I thinned the sealant with a little carb cleaner so it was thin coat) to get it sealed. Hopefully there'll be no leaks!

I did flush the passages was a pressure washer and detergent.....hopefully their clean.

No need to be nervous yet.....I still have 100+ hours of head work to finish, and another 100 hours of "other" stuff. I'll be nervous as hell on crank up day

[mk e]

Looking over my list, left on my short block task list are:

Remote oil filter adapter (the filters on top on the block won’t work anymore) – 6 hrs
Fit crank pickup (this is also the lower flywheel cover most likely) – 10 hrs
Add TDC indicator – 2 hrs

I also need to decide if I’m keeping the mechanical water pump so:
Mount water pump need to move up the list I guess…..it 2 hrs which is plenty to mount a full pump but lacking is the task includes making a pump housing.

Then back to finishing the heads I guess.

I also took some time and broke out the “to run” items from the “to drive” items and it says I should be on the dyno in late summer…depending on Lana’s ability to expand my Honey-do list…..but I’m thinking that I’m going to start pushing back as hard as I can to try to finally push this engine over the finish line this fall and the car out on the road next spring. We'll see how this works out for me.........

[tazandjan]

Mark- Sounds like a doable, if ambitious, schedule. Tell Lana it could be worse, you could be out fishing or playing golf every weekend. This way she always has you within reach.

Just make sure you're wearing a lacrosse helmet when you say all of this.

[Pizzaman]

Helmet?? More like a bullet proof vest.

She's old school.

Oh yes and for good reason. If one comes into middle of this thread from either web site.........first 2/3 on one (200)pages and second 1/3 (100)pages(6000 posts total) on this website one will get only a glimpse of this process and not the full effort. By reading entire thread and getting caught up does several things mainly it allows one to realise just how many modifications can be done. This has been very useful for me since I have several engine conversions in process. They are mainly twinspark conversions. From a Nord style 2L Alfa and later twinspark 2L. with a handful of extra parts and a later 155 head and EFI using Hayabusa TB's, 600cc TB's or the TWM throttle body intake manifiold advance the overall designs in a similar fashion as you have. Your efforts cement my ability to accomplish my effort. Yours is clearly the greater amazing effort. 2 engines, one stock, one TS and a head gives me 2 superior engines with efi and VVT.

I asked you to read and comment, in another thread, probably missed,on Alfar7's (search threads and posts) commentary on cam designs. He makes his own cams and is well respected on the AlfaBB and the alfa race community. His main effort seems to be lobe shape(ramping as the critical factor for longevity) and not so much ultimate lift. Torque wins races not horsepower, and uses higher torque obtained at rpms signifigcantly lower than max rpm, a 1000rpm less. He is a succesful racer and recommends several of his designs depending on use but is well aquainted with the various cams from many makers. Its clear you understand much of this yourself and would like to see your comments. Is this possible?.

I did pop over, but Alfar7 is pretty active over there so I had some trouble finding exactly what you were talking about.

I guess my thought is that there are a lot of general rules that are usually right ….well maybe relationships is a better way to say it.

For example gentle ramps are good for life but BAD for power, the compromise generally involves making the valve train as light as possible so as steep a ramp as possible can be made while maintaining acceptable component life.

The “torque wins races” saying is true in some ways but false in others. An F1 car is pretty fast but doesn’t make very much torque…about 250 ft-lbs. The real question is more like “is the engine optimized in the rpm range I need”. When the engine is optimized the torque curve will be relatively flat (…say with in t 10% of peak) over the required rpm range. Then the question becomes what exactly is the required rpm rang? Set it too wide and you will be throwing away engine performance, too narrow and you will to throwing away car performance….there needs to be balance just like in everything else in life.

Lana's got me back on moldings and painting so.....a decade from when I started or do we start counting from 2010 or 2011?

She says that when the painting is done (yes, I had her clearly define what "done" included...in writing ) I get an undisturbed month in the shop...of course by the time I finish the painting it will be spring yard time.

[Granucci]

honeydos are mathamatically the only number that's simutaneously a positive and negative number....so, can't help on timeline computations, but on a side note: The originator of a honeydo is in a universe of physics all them their own...good luck


Final note: IF this project ends, I'll have no reading to do and that would be a huge loss in my interwebs experience.
