Initial print has all bolt holes in line. Tonight I will bring the bottom hole 1.5 inches inboard to try to tuck the alternator a bit more and allow the turnbuckle to to crank tension into the belt. The planned location for the turnbuckle will be fairly close to a straight line reinforcement which should be a bonus to preventing any major forces tweaking the pulley out of alignment with the crank. https://i.imgur.com/GrMtwfb.jpg Also got spacing for head bolt accesories dialed in so I can make my coil and power steering bracket once all the parts arrive. Once again, nice work I’ll just share what I’ve found to work well... underdrive pulleys. I zing the shit out of mine and have never thrown the belt. |

I zing the shit out of mine and have never thrown the belt.Underdrive pulleys somehow stopped all the spark knock issues I was having with my old ‘95 Mustang GT. If nothing else, they were great for that alone. |

I zing the shit out of mine and have never thrown the belt.Went with a 2 groove V-belt March pulley. Think I went 5.75 inches instead of 5.5 inches just to spin the alternator a little faster for city driving. The power steering pump is gonna be tits. Comes with a 6in pulley and I could run to 6500rpm without worry of over spinning the poeer wteeri g pump. Love that the pump can be tuned to custom dial in power steering assist. My V2 timing indicator bracket managed to hit the oil pan but I kicked it inboard like 1.75 inches. About to bring it back a 1/4 inch and print another one. Once it is a nice fit I will finalize the curvature of the bracket and try to put a bit more meat in around the mounting holes on the pump. |

Just a heads up when you do the trans swap. I bought a swap over crossmember for the T-5 that has the parking brake bracket built in. When I release the parking brake the spring pulls the fulcrum arm in all the way and screws up the parking brake system. For some reason the V notch in the fulcrum will not stay in place on the crossmember. I think it has something to do with relocating it and the geometry in the new location with relationship to the spring location from the factory. I just need someone to operate the parking brake while I observe what the hell is going on under the car. I might have a fix this weekend for it. I'll keep you updated. |

I dont live in a mountainous area so if I have parking brake issues I will leave it in gear till I can unfuck it. Will be going through modern driveline for the swap. If any issues come up I should be able to 3D print mockups then machine my way to a solution with aluminum. |

Line the SN95 brakes I put on mine. Mountains or not, you gotta use them to keep calipers adjusted all the time. |

Mountains or not, you gotta use them to keep calipers adjusted all the time. Not gonna be too worried about the parking brake. I almost bought a rear that was sans-parking brake and just nasty boi race set up. I am familiar with the SN95 setup thanks to my Cobra. Once I get the rear end/suspension installed I will get to see how the parking brake situation lines up. I know Shaun has a video in his parking brake setup. Just have not watched in some time. 99% sure it is an inner drum/hat style disc. I am more interested in how the floating rear axle will eliminate pad setback for cornering/braking consistency. |

See if I can ballpark the HP from E/T given weight. If I feel something is off I will go for a tune and retest. Friend of mine who drag races may go for that dominator looking Holley EFI kit. He was just breaking into the 8s for the 1/4 before his class went away and he switched to 1/8 mile. Others he knows use the Holley kit and are getting decent consistency even out of the box off self tune. /edit Stimmy rustled my Jimmy enough today to order my T5 swap kit. If I could get my lower control arm mounts welded in with my subframes I could get thd car home and be able to wait on the suspension while starting the engine install. I want to be able to drive the car over to get the subframes welded in proper and have the lower control arms welded correctly. |

Once the trackings go out for my trans and my suspension I am calli g q hold on the package for pickup. Will be able to spot damage there at the facility and make a claim right there if I have to. Spent today machining some new badges that are gonna be part Terlingua bunny, part street or track logo, and on a carbon fiber background. Bunny will be red while rest of bqdge is polished aluminum with a sealer set against the carbon fiber. Should look outstanding on a black car that has been debadged. |

These will take awhile to unfuck and repolish the aluminum. The other set I poured yesterday will hopefully turn out near perfect. Thse dont look too bad but the micro bubbles piss me off. But in full sunlight they are blinding and the effect of the carbon fiber dancing in the sunlight is awesome. |

Again, let me verify that and get back to you Given I am a 302 based block I am hoping I dont have to mod hedders much. Looking at the prothane mounts and probably grabbing them along with an overflow tank for the radiators. Beginning of next week I am probably ordering the EFI. |

I have a set of stock '66 motor/frame mounts if anyone needs a set. They are about to get purged with my pending move. |

Ordered Prothane motor mounts and an aluminum overflow catch can. Car got dropped off to have subframes put in today. Once I know cost on that I am ordering off my EFI kit. While I was there I showed them the emblems I made for when the car is finally done. Mentioned I prototype with my 3D printer and then CNC some parts. Their ears perked up and they took me to the garage and showed me a 50s era GMC emblem they have for a custom truck they are working on. Helps that I know two of the owner's nephews and one of the shop hands is a co-worker. Time to fire up Fusion 360 and see if I can marry my CAD/CAM emblem interests into a side hustle. Maybe a swap of my labor/work for their labor later on when it comes time for body work. |

I dont want to do it as a complete unit as I may be doing a lot of it by myself so I want it as compact as possible. EFI kit has shipped. Only waiting on radiator backorder and for suspension to ship after it is back from powder coat. Stabbed distributor in 331 along with the coil mount going on. Got last belt installed. Motor mounts need to be clearanced to clear around some ribbing on tbe dart block around the motor mount holes. The alternator bracket at the water pump mounting spot needed some careful spacer stacking to not have to modify the bracket which is meant for a mechanical mount. Due to the spacers it pushes out the bracket to where it almost becomes a issue for the belt. Wound up with about 1/8 of clearance but I am calling it good. https://i.imgur.com/dSlYOLu.jpg https://i.imgur.com/Mq0IJtH.jpg Finally got badges I am completely happy with. No bubbles in the epoxy. https://i.imgur.com/7ESKHbD.jpg |

Got manifolds disconnected tonight. One side unbolted the other side had to have the pipe cut. Dropped the drive shaft out. Got all the bolts off the bell housing and the flexplate. Dont feel like dropping the trans tonight. Gonna come back to the nasty job of the cross member tomorrow night(it is caked in years of road grime and oil leaks) and see if I can drop the trans. 3 of the bolts holding the bell housing in place where barely more than finger tight. 2 bolts were doing most of the work. Then the engine should be ready to come out. Once I can get the car back on the ground I can climb into the engine bay to start cleani g and cut the radiator support for clearance needed for the new radiator. Also have to modify the firewall for where my hydraulic clutch bits for the master are gonna bolt in. I am sure I am gonna enjoy laying on my back to add a fuckin 3rd pedal into the pedal support area. Figure I have a couple nights of clean up to get the engine bay looking semi decent. |

My buddy seemed to think "all madter cylinders are the same, front is front and rear is rear." Nope. Good to know, thanks. I use a manual (non-boosted) aluminum m/c out of an ‘83 Ranger. Direct bolt-in. An old-timer Super Stock racer (RIP Alex) turned me onto that. 15/16” bore, no external proportioning valve required, perfect for OE Kelsey-Hays four-piston fronts and rear drums. About half the weight of a cast iron m/c. Your SN95 deal is probably lighter yet. My car originally had the old cast iron single-stage fishbowl m/c. That was one of the first things to go. I believe DOT required two-stage masters beginning in 1967. Some ‘65 and ‘66 guys run a ‘67 master. My ‘83 Ranger deal makes far more line pressure, and is much lighter. With aggressive pads (which I run), my car will put you through the windshield if you’re not buckled in real tight |

My buddy seemed to think "all madter cylinders are the same, front is front and rear is rear." Nope. One of these is also SAE threads while one is Metric threads too. When I did my '95 GT to Cobra brake conversion, I had to use a '93 Cobra MC because it matched the threads on the '95's brake lines that I think were SAE while the Cobra in '94-'95 I think was metric?? Ford shit the bed on the '94-'95 with so many different mix ups of SAE and Metric. |

Yanked my bent bumper off today and yanked the battery tray. Sanded out more of the passenger side apron and painted it along with frame rail. Cut down the motor mounts so they will bolt up to the block. Clearance is super tight and after I adjust one of the motor mounts I may have to tend the bottom most tubes for a bit of clearance. Gonna work on other apron and frame rail tomorrow. Need to clean up the engine bay and get her painted. Getting closer to being able to drill firewall and cut core support for radiator. Next up will be indexing the bell housing to the crank. |

Details of the Unisteer install experience. Think I should have been more sarcastic? Hopefully it will help anyone buying a Unisteer rack. Still cannot believe the tardlets deleted the windowed holes of thd crossmember. Another video with a bit of a walk around coming later. |

and have never thrown the belt.
