The Shop Truck

1971 Chevy C20 with a custom flat bed.
They're Roadformer clamps from Amazon. They're not stretching, they're just settling in or something or sinking into the silicone.
 
Mechman got back to me, apparently the racing alternator is in a 128mm case vs the standard 138mm case. Nothing else is different.
I may have to upgrade when I reimagine my accessory drive setup then. :thinking: :waytogo:

What’s the price difference? Can’t imagine it being that much weight savings but every little counts.
 
They used to call it the race one because it was the only one designed for 7000+ rpm.
I'd guess now they won't need to call it the "Race " one.
 
I've never had that problem with clamps either. I try to use the constant torque as much as possible but I've also used a ton of Tbolt clamps and never seen that. I'm not sure I'd trust them settling in. My gut tells me it's a material problem.

The 240 Amp race alternator that I have is $499 from Mechman, the 250 Amp non race version is $524. So no price difference really.

The only material I could see getting deformed would be the aluminum tubing or the silicone couplers. These look to be high quality 304 stainless heavy duty clamps.

Import 304 problems go back decades. Thread deformation during tightening, or vibratory deformation, the thread class actually formed from clapped the **** out rollers, mislabeled material, faked mat'l certificates, etc has all happened and will continue to happen. Could be mat'l, could be fixtures, could be the nylock nuts, or all of the above. This shit is only getting worse and invading all levels of parts at an exponential rate. I'd love to say it's import only, but its not.

Just keep a watchful eye is all I'm saying.
 
I'm pretty sure we'll be driving the truck tomorrow, but def by Sunday. I finished up the last of the engine connections, we've been trying to figure out where to mount the catch can and finally decided to just put it on the firewall. We're going to try not recirculating it, but if it gets too annoying I'll run a hose over to the intake tube.

With that done I replaced the turn signal assemblies in the bumper (one had stopped working) and got that installed.

Amber was done with work and helping at this point and she wanted to get the grill in. We wired in a connector for the second set of turn signals in the grill, finished installing the hood release cable, and wrestled the grill into place.

It's nice to have my tool trays back, it's so handy having a place to set things down while you're working on the truck. I've missed them the last couple months for sure.
 
I have my catch can recirculating.
And I'm debating doing it like yours. Because even with it, my intake is coated with oil. With tiny puddles at the back when I'm diving it regularly.

I've never gotten oil in the intake from mine. But haven't put that many miles on it though.
 
I built my own engine... I am lame.
I have seen you behind the wheel you are not lame definitely entertaining.

I act like I have an unlimited supply of cash, but if something goes pop it’s down for a long time. Luckily it’s been 7 years.
