Ok this actually wasnt all that bad to do. So, i ordered a Transgo shift kit, and a lubelocker pan gasket:  This shift kit is hilarious. Its like 5 springs and a piston!  I guess if it aint broke, dont fix it right? So theres not a whole lot of work to do here, but it requires removal of the valvebody to do it. This is entirely possible to do with the trans installed, but since ive already got it out, i opted to do it with it upside down on the cart.
Ok, i finished refreshing the NP203/205 doubler. All degreased:  NP203 range box removed:  Seeing as this kit is from 2005, the intermediate shaft is a stock shaft cut down & resplined, as opposed to a new 4340 shaft that most kits use now. Fortunately, the shaft still looks good:  Ok, lets get this thing cleaned up!    ...and done! All cleaned up, new output shaft seals, new shift rail seals, and a fresh coat of paint!  Next up is the transmission...  Talked to the builder today. Heads are in and he's already started cutting for valves. Currently looking at decking the block .010 to bump compression a bit, but we'll figure that out once the heads are done. Hes going to order the timing set/cam/lifters/etc tomorrow. I ordered a new Kaase oil pump + hardened shaft from ARP today. Also ordered a wideband O2 + controller & an adjustable FPR as well so i can tune it once its running. Researching online it seems its hit or miss if its possible to tune it on the stock injectors so ill have to get it running, mess with the fuel pressure, and then (probably) have to go back and get bigger injectors. But thats a ways off yet. Disassembled & started cleaning the NP203/205 doubler; hoping to start putting that back together tomorrow. Fed Ex doesnt seem to want to deliver my shift kit (no updates since saturday) so doubtful ill be doing anything to the trans this week. Ok, so referencing this pic i took a couple weeks ago:  I decided to just go for it, and notch it. Here's hoping i made it the right shape! Frame all cleaned up:  Not real easy to see, but ive drawn several different lines on the frame, to try to figure out how i want to do this  The point of no return!  Here's the piece i removed for reference:  The rough mockup in cardboard:  And here's what i ended up with, original shape was pretty close:  Fitting/welding:
...and the end result!   There is a ton of room. This has got to be good enough, altho im not gonna lie, im a bit nervous about this one. Mainly because i wont be able to verify its good until the motor goes in. Here's hoping! Talked to the builder this morning. Block is going to need .015, so we're gonna go right to .030. Crank will need .010 on the mains. He's on board with that cam i posted yesterday. Still researching pistons, but it sounds like he's found a set thatll get us ~9.6:1 compression, which should be pretty sweet. Unfortunately, both F4 heads are cracked! One of my E7 heads is cracked at an exhaust flange as well, so its looking like new heads are going to happen. Well, the block, crank, rods, pistons & heads are officially at the machine shop! He's figuring atleast .010, so most likely will get a .030 overbore. No idea on deck height at this point, but we might take some off to bump compression a bit. Thinking about running this cam: www.compcams.com/xtreme-energy-computer-controlled-hydraulic-flat-cam-for-ford-429-460.html And im thinking about this throttle body as well: www.summitracing.com/parts/BBK-3502 Were gonna try and build something torquey that will still run on the stock EEC. Im expecting to have to adjust fuel pressure a bit but hopefully not much else. We'll see how it goes! Plan for the rest of the week is to clean up my mess in the garage. Then bust open the 203/205 doubler, give it a good cleaning, change all the seals and get it ready for re-installation. Then im gonna set the C6 up on the bench and slap a shift-kit in it while im waiting for the motor to come back. I also want to change the converter while its apart since its probably original from 1988. So lots going on right now, even if there arent any posts showing it! Lifters and cam are now out:  #8 rod bearing. This is the worst of the bunch, but not by much: #6 had a broken ring, which corresponds to the score in the cylinder bore:
 #1 main bearing pretty worn:  #2 is shot! This is the worst of them:  All main bearings worn, with corresponding scoring in the crank journals   Tuesday this mess of parts will be going to the machine shop so we can see where we stand.  The verdict is in: She needs a rebuild. I suppose we already knew that, but heres what we found: Your typical wear in the cylinder bores:  And a decent score in the #6 cylinder:  All the other cylinders look decent, so i flipped it over and pulled the pan.  The oil pump screen is nice and clean, and so was the pan. Spun the motor over via the crank bolt, and you can hear the #8 wrist pin clunking away. Its pretty sloppy. So this is the source of the noise. Now to find a machine shop willing to work on this thing... |
