So I am trying to keep my project moving, although I haven't been able to get my hands on the car in a while. I was in Europe for 2 weeks and just slammed at work. The coming weeks don't look any better. I continue to finalize plans for the motor and after speaking with John Dougherty today I think I may have changed plans for my camshafts. I was leaning towards stock S MFI cams but now may be leaning towards DC30 Dougherty Racing cams. The power band is too high and 'peaky' with the S cams (coming to life at 4500). The DC30 sounds like a good match for the compression I plan to run(9.5:1) and will provide more mid range torque and a power band from 3500 to 6500. Seems like a better option for the street. Before I send my money to John, any other thoughts out there?

sounds good - the original grinds were a little limited by technology too rel. to today's - IIRC, it has to do with the ramps

right - i guess they are a more "modern" grind. better lobe centers. the DC30 is similar to the E cam, but with longer duration. you do need higher compression with these, but i was already planning to run the higher 9.5 compression (8.5 wont work well with these cams). i did just shoot a note to Mark Jung to confirm that the specs we agreed to on my pump will still work (I had originally told him i was going with the S cams). Same conversation needs to be had with Burnham for the throttle bodies and stacks (haven't sent those quite yet anyway).

I will be going with JE 87.5 pistons (9.5:1) and LN Nickies cylinders. Just need to accumulate a little more of my 'car allowance' for this investment :) Not cheap but some of the best pistons and cylinders out there.

are you going to get any coatings applied to the pistons?

i dont think so, but let me know if you have thoughts. if you are talking about burning pistons, this setup is designed to run cooler. the pistons are forged and the cylinders are billet aluminum - this setup is designed to run cooler and endure tough forces (e.g. high compression, etc). i certainly need to get the ignition and fuel all dialed in correctly to prevent burned pistons and other issues. i plan on having the machining work (heads) done by Ollie's so i may need to pick their brain more about what i should be doing with this build.

the more i go down this build path the more i am wondering why i am not just buying a 3.0 or 3.2 - this is much more expensive!

Ha!

Well, I did buy a 3.2L but I also hotrodded it - no diesel tractor pump, but PMO carbs (full caveman), cams, twin-plugged, CR ~~ 10.4 or something

I had 3 different coatings put on the JE pistons (in 3 different places) - not at all critical but it was fairly cheap

Sounds like an awesome build! The MFI work is pretty expensive on these things (and the pump is pretty tractorish) - but then again, PMO's aren't cheap! I was just saying I would have gotten a pretty good performance bump buying a stock bigger motor.

I am not planning dual plug since I am going with 9.5 - but I may have my heads done for dual plug since they are going to the machine shop anyway and just plug the extra holes. this way i can always go dual plug if i want to down the line.

i will look into the coatings you mentioned. your build sounds awesome!

if I had it to do over again I might just have built up a 2.7L motor and put a typ 911 tranny in a lightened up '72 body

you are smart to drill the holes for twin plugs now

Have Fun

Yes, a 2.7RS spec motor (or even punching to 2.8/2.9) would be a good way to go, but this would have added several thousand dollars to my build for all of the necessary machine work (i am keeping essentially a stock bottom end and little machine work beyond the heads). Plus, i still would be stretching my 4R MAG case (would be better if had a later 7R case) to do this. In the end, i am opting for a good amount of HP from smaller displacement while keeping my original matching numbers case and good dependability. I should come out pretty close to the 2.7RS stock specs (I believe it was 210hp?) with my build - hoping in the range of 200. A guy on Pelican gave the tip about the dual plug prep now 'just in case' - seems smart.

Dying to do more on the car but not having much time, after work tonight I attached my restored S calipers to my restored Bilstein strut assemblies. Also installed fresh Porterfield R4-S pads. It did require trimming my stock M caliper dust shields to fit these larger calipers. I looked up photos of what the S dust guards looked like and trimmed mine accordingly using my dremel. Not much progress to speak of but they sure do look pretty.

Managed to get a roll of old stock basket weave material from a guy in Austria. This is the perfect size roll for redoing the dash insert. I plan on removing the radio and possibly the fresh air controls, so this roll will be used to finish off the dash for a clean uninterrupted look.

Holy Moly!! You had to go to Austria?? I need to do that too...

Haha I was just in that neck of the woods. I actually packed extra luggage planning to bring parts back from my trip out there - but came back empty handed. I had visions of Fuch wheels on my lap on the plane back home :)

The guy I got this stock from is on Early S, but in Austria. Was a good price too! But he is out now.

Ok so I wanted to start cleaning up some more parts that have been removed from the car. I started with the fuel console. The fuel filter was probably not replaced in decades as it was really hard to remove from the console. The rubber seal was permanently attached to the console. I had to pry it off and as laughable as it sounds it took a good 30 minutes to get this thing off! When I finally got the filter off it was full of some kind of dust. Anyway, this is another minor update but I was able to disassemble the fuel console and thoroughly clean it and all the fittings. Should have taken a before pic as this thing was a mess. I may throw some of the fittings/hardware in the next bag going to the plater. Need to get a new filter to attach to the console.

Still not much time to work on the car. Actually spending more time marketing my 993. I still may change my mind and take her off the market - but as of now she is for sale.

Did buy this from John at st-classic. Need to finish it. Continuing with an ST/R/RSR look with the motor build.
