Classic HorsePower Scratch GT40

[Devin]

Been a while since I’ve had all the bodywork all back together but since all the guide pins, latches and hinges are in place, it was time. Now I’m working on front clam dzus fasteners before final bodywork leveling and front end gaps. Also time to start looking at fabrication of the deeper twin nostrils (currently not so deep) that will move the air in the right direction post radiator & fans.

Make sure you have any/all weatherstripping in when setting your gaps.

In preparation for the twin nostril modifications, it was time to secure the panel with Dzus fasteners. After a lot of measuring, marking, drilling, measuring, modifications, measuring, drilling and installing, the fasteners are complete. Through the process I realized that one corner of the panel opening wasn’t deep enough to allow proper securing of the wire retainer and proper flush fitting of the dzus once in place. A quick cut (albeit not fully cut free) of the corner support structure allowed it to be displaced another 2mm deeper and epoxied back into its new location. A little bodywork and no one will notice the correction to that corner structure.

The twin 9” Spal fans arrived and I designed and ordered the fan shroud on SendCutSend.com to be delivered in about 10 days. This will be my first experience with them and will enter a build log entry specifically on my impressions using their website and end product.

I felt the need to drop the drivetrain back into the chassis today. I’m getting ready to source and design the remote oil filter and cooling system so needed things in place to see the best location for components and lines. Also was an opportunity to clearance the bulkhead panel and the rear clamshell interference with the transaxle. Lots more planning and engineering yet to come on the fire suppression, cooling, electrical and exhaust system before thinking of removing the drivetrain for the last time.

Davin, I am surprise that you can fit the engine in the engine bay with the oil filter ?

Now that the engine is back in, I’ve been working the accessories, brackets, with their positioning and belt adjusters. I found that how I initially planned to position the AC compressor with its supplied turnbuckle adjust wasn’t going to allow spacing from the rear removable bulkhead panel. Spent a session of experimental positioning and varying lengths of adjustment point…ended up having to fabricate a custom length turnbuckle after ordering a set of paired rod ends. After some measurements and TIG welding, looks like it will work great and will order some correct sized bolts and spacers to complete.

Where did you get your pully sets?

I ended up ordering their alternator & AC (high mount) system. If you can’t tell, I flipped the AC extended mount upside down and lowered it one bolt hole. It still feels very solid and with the AC compressor rotated 90 degrees on its side will be just enough room for clearances and hose connections. I don’t care for their 3/8 bolts going through the 11mm compressor mount tabs so am currently sourcing an appropriate sized tubing/shim to take the slop out of the sizing mismatch and potential for belt misalignment. Once complete, I’ll source the appropriate length of drive belts.
