I use this style of fuel filter without the screen for the PCV restriction. I'm running a Holley also so it's plumbed to the base of the carb with fuel line. I use the factory pipe coming out of the shroud. The end that normally hooks into the air cleaner has one of those mini air filters clamped to it. The "T" on the pipe goes to the carb with this (screenless) fuel

LM shoes also cross reference to the 1st gen Camaro (same spindle as the A bodies). So far, I've never had an issue with shoes on the rear of my Corsa, parking brake hookup and all. Availability was never more than a day at my FLAPS if they weren't on the shelf. One thing I always look for in brake pads and shoes is a "FF" rating. This refers to the friction and heat ca

Timkin is the industry standard. They literally wrote the book on tapered roller bearings (I studied it in college). SKF has a good reputation also. Either would be fine. If SKF is the only option, I wouldn't hesitate.

Try the "old fashioned" way of bleeding the brakes with a buddy pumping the peddle while you crack the bleeder, etc. I had a hand pump style pressure bleeder thingy and never got it to work as advertised (I had issues, some of which were self-induced for sure) And I second the idea to put plugs in the MC outlets to test it.

I got a set of turned down hubs from Mel at Vairmart here in San Jose, CA. He said he was going to do a batch. This was a while ago but depending on your situation, it might be worth a call.

I had pretty much the same problem with a new clutch disc from Clark's. The only way to get it into gear when stopped was to shut the engine off (shifting on the move was no problem). After a 100 miles or so, the problem solved itself. The theory was that the disc was a bit too thick or had high spots and wouldn't completely disengage even though the linkage was adjusted by the book. Se

It can be done with a bubble level and a ruler. Here's one with pictures: One thing you need to do between putting the car on the ground and taking a measurement is roll the car back and forth to settle the suspension.

Regardless of which side you are looking at, when you spin the adjuster star wheel to elongate the adjuster assembly, the paw riding in the star wheel teeth should ratchet. Another way to say it is the paw on the star wheel should prevent you from shortening the adjuster assembly (unless you manually lift the paw off of the star wheel teeth).

It looks like the price went up $10-20 in the last ~6 years since I bought a pair from Rock Auto. With free shipping, this is a good price. They are also a good upgrade. I found that these are much more fade resistant than the plain cast iron drums. These are a classic example of the 80/20 rule: 80% of the benefit for 20% of the cost (compared to discs)

16 on the highway. Sometimes better but not often and not by much Best was 22 on California Highway !. Average speed was 40-50 mph and I was cruising with the traffic. I'm not sure I can expect much more out of a Holley.

I am running a Holley 8007 390 CFM on a center mount manifold in my 140 Corsa and have a power valve installed. Before I get into that, I have to say that after rebuilding and tuning several carburetors for my Chevelle, I thought I was pretty good at it. Then I tried to tune the Holley set up on my Corsa. Needless to say, I have been humbled. If you have a Holley rebuild kit with a power va

Those Mustang bushings look very similar to the Clark high performance bushings: Which look incredibly similar to the Nova/Chevy II "heavy duty" bushings: I have a set of the Clarks HiPo bushings on my Corsa. The only downside is that the max caster adjustment is limited compared to the stock bushings (the stack up takes more space on the rod). The upside is that they la

I paid $500 for a 140 about 6 or so years ago, shrouds and heater boxes included. I paid $400 (IIRC) for a 6 bolt 3.55:1 transaxle just before COVID. Different sellers but local. Both had minor issues I had to fix during the rebuilds.

My 140 has a OT-20 (which now called the TB-20). As described it is a very good all around cam. Nice lopey idle and revs freely to 5500 RPM. I have a Holley 390 on top of it. Everything else is stock. That being said, I don't know much about turbos. I think it would be worth some investigation into what makes a good turbo cam. It might not be the same as a naturally aspirated cam.

Aren't these the same bushing as the Chevy II strut rod bushings? Rockauto still lists the Chevy II but are out of stock (both the original style and "improved design"). Summit Racing has both styles but the improved design is out until August. Hopefully it's just a supply chain issue

Maybe try the screwdriver trick with the starter installed. If it works ok that would lead you to troubleshooting the harness. If it doesn't work maybe the gear clearance is too tight.

When I had glass packs (similar to the Harley mufflers; long, skinny and loud), there was enough play and give in the slip fit pipes (I had to add a step up adaptor) to angle the passenger side outwards. They did not protrude too far past the rear valance so the difference in angularity was not too noticeable.

I am running a '70 Chevelle disc/drum 1" bore master cylinder with Wildwood twin piston GM Metric calipers and S10 discs in front and stock drums in back (15/16" diameter wheel cylinders). Works great. I ran this master cylinder with the front drums for a few weeks before I could get to the disc upgrade (external residual valve added to the front circuit). Pedel force with the

I found these dimensions on the interweb. I think the 109.8mm dimension would be a problem with the Corvair spindle. Looks a little long. Then there's the matter of the bearing inner race ID. I'm pretty sure that if there was an integral hub/rotor part that works on the Corvair, we'd know about it. I just did a Scarebird bracket S10 front disc brake upgrade on my Corsa. The

Good point on the interference fit. A 3A is bigger on average but probably not .377". You could helicoil the hole in the case (they do make a locking type if you wanted to go back to the stud). Not to sound pessimistic, but given the loose fit, you might damage the threads at some point. Preemptively doing a helicoil now might be better than getting stuck in the future.

Unified threads come in different classes of fit. I bet the original GM stud you are dealing with is a clas 3A. You probably could find the right bolt (technically a screw in this case) from a specialty fastener house. Or just modify the stud you have. Below is a cut and paste from the innerweb.

The problem manifests as a misalignment of the pin bolts. I can get one or the other to screw in but not both. When I line up one of the holes, the other is off. To line up the other, I have to slide the caliper along the caliper slot. When I do this, the first hole does not line up. And I can't rotate the caliper in the bracket to get both holes to line up. (If I could rotate the cal

Hi Kids! I have run into a problem with the parts I have collected for my disc brake conversion (I listed them above). I think its the Scarebird bracket but I'm hoping that some feedback form this group will either confirm or deny my assessment. The issue is similar if not exactly what solo2r ran into in this thread: I did a little measurement and it appears the nuts welded in

I have two experiences with Clarks LM HD Springs and they are different. About 8 years ago I purchased and installed a set on my 65 Corsa coupe. The results were very much like Dave's pictured above (maybe even a fraction of an inch lower) My buddy recently (within the last year) purchased and installed a set on his 65 convertible. His ride height ended up higher than he started (whi

Rebuilding the differential is not that bad unless you swap in a new ring and pinion. If you do that, it's more than than likely you will be pressing the pinion bearing off and on a couple of times to get the gear mesh (pattern) correct. When I did mine (reusimg the ring and pinion), the same shim worked out and I only had to press the pinion bearing on one time. (Ok, full disclosure; I

California Corvairs has them for Cheap If you are adding a T-block for a separate rear circuit on a 65, then either the 65 or 66 version will work since both T-blocks will have at least one 3/16 side hole for the rear If you are doing a 66, then you'll need the 66 since its the only one with a 1/4 side hole for the rear circuit. (I am pretty sure the larger hole is for the rear)
