Kind of went thru a similar situation with a buddy and his fresh rebuilt L24. After the engine was warm it would rattle like detonation at around 2500-3000 rpm. We did every thing timing including a different dizzy. Tore the motor down for fear of damage. A different engine shop looked at and determined the bores were over honed and left too much piston clearance. The original engine shop tried to save original bore size and bones the sh!t out of it. I think it was like 6-8 thou over spec. Couldn't find any other reason for the sound. Engine is NOT back together yet. The bores looked like crap for what little miles it had on it.

They wouldn't ship?

I would also recommend stock ones in good shape!

Might have luck on eBay . I found old new stock Fuji valves pretty cheap. My machinist didn't like those SI valves . Something about the hardness not up to snuff

I have both trans - can I help by measuring something?

Great ! Options!!

I saw the pics of this head and its just a stock 42 chamber. I thought it was curious that it had this copper sealing on a basically stock chamber. Maybe had high CR pistons and was running race gas?

Not for nothing, but it seems like a lot of work when you can get the stock tach to work pretty easily with a tach adapter. For the most part I've read that the OEM tachs are pretty damn accurate and some can be adjusted. Buy a 50$ tach adapter and wire it and done. It will look stock and match the rest of your gauges if still using OEM. Since I have had my adapter on there it has worked flawlessly with the MS3X. Didn't you post that you couldn't get your tach to work before? Might give the wiring another try. It will a ton easier and faster than retrofitting something else. just saying...

That will have some compresson with the MN47 head.

You should be able to use a tach adapter to make the stock tach work which is probably better than most you can buy. I even got my current driven tach to work with MS3x with the 8920 adapter

Not all Pcv,s are the same, so choose wisely. You can use a stock Pcv , just put it in the middle of the run and use hose clamped on to the threaded end. I pulled a valve off the shelf at the parts store based on it fitting my set up, but it did not work the same. It bipassed quite a bit of air at idle vs. the OEM valve that hardly bypasses any air at idle. I was able to tune the car this way and it actually worked really well for idle and start ups, but didn't realize how different it was from stock until I put one on. I wish I knew what actual Pcv I was using ( for what car).

Beautiful build and attention to detail. You got this far so tuning the carbs should be bad. Didn't read the whole thread but hopefully you have a wideband to help you tune

Then please describe your build

I like the no spark plug wire look, but the nostalgic look of your motor it doesn't look bad. Could you run a Subby type COP and just go with a CAS ? I think the little coils would just blend in nicely on that valve cover.

I think the speedi sleeves are .011 thick

It's a shame the Speedi sleeves aren't a tad thicker-that would be a cheap ,easy fix for the shim

It takes a large amount of research and a steep climb on the learning curve for the MS. Each vehicle having it's own path. It WILL click soon enough if you stay at it. My experience is with MS3 and no dizzy, so it would take me lot's of studying to get where you are. I would suggest getting on the MS forums, buy someone a starbucks by donating to the forum and go from there. Make sure you can upload your settings in your thread and then be patient. Don't expect an immediate answer , but sometimes a direction to go. Take your time and write your question in much detail. I would say that since the car runs, you have a HUGE start on your conquest. There seems to be many issues with losing communication with rpms. I believe it's just a setting-ask me how I know

YES - us T-5 guys want to know- lol

It's a shame you didn't measure that mark from the bell housing flange so we could have a reference

Slip a link-best know what your doing there, though I've been tempted to advance timing a weeee bit more.

I was surprised and enthused by the price-if you didn't notice-1700$ for the whole shebang!

Might need to direct your attention to that relay as far incoming trigger wire and associated grounds with that relay . Maybe swap out a relay and try.

The wagon is still going!! So no holes:) Well I have a non webbed 42 that I would like to upgrade to 14mm Oring at both ends. So I need to get the intake reamed out for 14mm injectors. Would like to run high impedence to simplify things. I am also making a custom plenum/intake using a canon intake that I need a fuel rail for. Not sure of the part out date-but it will happen

I would be interested in that trade for sure! I will be parting out a diesel in the short future and I will not be using the oil pan. AND I need a duel rail:)
