Re: G80 vs Truetrac

While the Detroit Truetrac is the cats meow right now, don’t forget that GM put thousands and thousands of Eaton zexel Torsen units in firebirds and Camaros for decades. Keep an eye out on eBay. I got my first one there for like $80. Served me well for years.

Re: Is the 4.3L an 'Interferrence' motor

Good point-good info. I’ve always been a draft horse vs. a thoroughbred race horse kind of guy. High compression leads to premium fuel and zero clearance. If I had money to spend on making hp. I’d be putting turbos on low compression big blocks. I remember watching a car show on the tv where they pu...

Re: G80 vs Truetrac

I have no problem with the G-80. It does what it does. The van moved forward as it s supposed to. It went sideways as a locker/limited slip is supposed to. In normal driving scenarios it acts entirely proper. My normal seems to be more towards to outer edge of the envelope than most as it states in ...

G80 vs Truetrac

As some of you may remember, my last van was equipped with Torsen carriers front and rear. When road cancer ate my beloved test mule to the bone, I found it’s replacement. My latest van is the spitting image of my ‘99. It’s four years newer with leather so it’s a bit of an upgrade. They both sported...

Thanks!
I’ve never understood why someone would design something like a zero clearance engine when you don’t have to. Things break-design it to live to fight another day.

Re: Is the 4.3L an 'Interferrence' motor

Search Results Featured snippet from the web The GM 4.3L v6 is a non-interference engine in that the valves open into reliefs cut into the pistons such that they will not contact the piston even if the valve is open to max lift with the piston at TDC. As such, if the timing chain has broken, turning...

Re: Hitch for '03 Cargo

Exactly right. Either way you will be fine. I can’t recall anyone ever tearing their hitch off their van. Just make sure to re-torque your hardware after your first use.

Re: 1987 Astro Tiger 2wd To AWD/4x4

Great project-I love those tigers! You will be going from carbed to fi right? If so you will need the ECM included in the swap. The BW4472 tc in the 93 was I tried and true unit but parts are no longer available. The np236 swap is all electric and electronic and I wouldn’t recommend it unless you lo...

Re: what have I done to improve my Astro over the years.

Nice list of upgrades! El Camino rear bumper huh? I’ve been spending quite a bit of time under my van lately needle gunning and rust proofing. I’ve been staring at the rear hitch and bumper set up looking to shorten the whole thing up. I’ve never really liked the way it protrudes sooo far past the r...

Re: Hitch for '03 Cargo

The first hitch you linked to has a bow to it that will match the curve of the rear bumper if that’s important to you but the other two have twice the frame mount surface and that’s a notable difference. The receiver on mine is tucked under the bumper cover and poses no obstacle. I never remove the ...

Re: G80 & GT4 for 2004 AWD Astro Conversion

Quote: I just picked up my Astro Quattro from the shop. I ended up going with Yukon 3.73 Ring and Pinions that don't appear to make any additional noise. This is with the the Truetrac in the rear and the MFactory in the front. The front torsion is mounted in the stock aluminum casing Just a minor er...

Re: NP 233 spline count appears to be 32 in and out

If by Blazer, you mean S-10 Blazer, then the doner vehicle also has the same 7.2 front diff. If you go back for the front prop shaft you can take measurements of yours before you go. If the shafts are the same length take the Blazer front diff yoke also. Then you can simply swap yokes and good to go
