    Stripped and cleaned (as good as I'm going to) and ready to go to the installer.

    This led me to look into the motor mounts a bit more. Turns out the adapters I bought work with clamshell mounts that have the bolt holes 3" from the mounting surface on the block. Mine were 2 1/2". This may explain why the motor mounts were so blown out when I took the motor out. Since I haven't spent enough on this money pit I ordered up a set of these which should fix the issue:

    While I was at it I ordered the fan shroud for it as well. I bought the fans a while back and this is made specifically for them.

    Overdue update: Bolted on the headers. They are close but I need some clearance on the drivers side.

    for DDing, you will just drive it in a higher gear around town.
    The Nova was my DD last year for a couple of months due to issues with the G5. Between the gas mileage difference (16 vs 33) and the upcharge for premium in the Nova it got quite expensive, relatively speaking. My daily commute (non apocalypse) is about 65 miles and 90% of that is at 70mph. I'm tuning to run 87 octane and hoping for 20mpg under normal driving. The 3.42s spin the motor about 11% faster than the 3.08s. So I could expect a 2mpg difference between the two sets. Assuming 10,000 miles a year and $3.00 a gallon that works out to be $167 in additional fuel costs for the 3.42s. That seems like it would be worth it. I think I'll order up the 3.42s.

    I knew I could count on you guys to tell me to run the 3.42s! If I were not planning on using it as a daily, I'd totally go 3.73s. Unfortunately, gas mileage is a consideration. That being said, I'm leaning towards the 3.42s.

    Drive shaft will be 5" aluminum one piece with 1350 u-joints.

    I'm working with Driveshaft Specialties to build me a driveshaft for the truck. Because the truck is a long box, a one piece driveshaft needs to be a bit ore robust than ones I've bought for the Nova and Mustang. The first thing we determined is that the 1310 u-joint yoke on the rear end will be a weak link. I have a new 1350 pinion yoke on the way to rectify that issue. The main considerations with the driveshaft are length and rotating speed. I can't do anything about the length (without making the shaft a 2 piece assembly), but I can influence the rotating speed with my choice of rear gear. Since I am taking the pinion yoke off, it seems a very logical time to install these:

    The question here is 3.08 or 3.42 gears. With my tire size and the overdrive in the 4l60E at 75 MPH the 3.08 gears will spin the motor at 2030 RPM and the 3.42 would be at 2250 RPM.
