I've been running a variety of C4 rear springs under my '69 as they're reasonably inexpensive, look stock, and fit the lightweight D36 batwing I adapted to my stock differential. I'd like to be able to "adjust" the effective spring rate, as the selection of stock springs is limited, and due to...

I'm planning to make some more SS insulator shims for my caliper pistons. In the past I cut the shims out with my plasma cutter, but that method always required a lot of additional grinding to clean up the shape. Just looking for suggestions on any better method. The new shims will be out of...

At the track day last week the brakes were fantastic when first applied coming up to the corner. If I did a quick second application of the brakes there seemed to be little to no deceleration going on. The pedal was high and firm at both the first and second application. It just felt like a...

Just curious if anyone knows of a site or source for brake rotors that could be ordered by size (and offset), not by make or model of car. Working on a project, and I can save some time and labor by finding a specific rotor for the application, instead of modifying the caliper mounts and...

Help a BB guy out here, please. On several sbc intake manifolds I see a couple vertical threaded holes (3/8" thread) on the center left side of the manifold. I'm drawing a blank regarding the reason they're there. Anybody have an answer for me? Thanks, Mike

I need to plumb up a PCV system for my street rod '51 truck. My present selection of parts on the engine doesn't accomodate that, so I expect I'll have to get fancy here. I'm using 60s vintage finned Corvette valve covers (with no oil cap or PCV hole) and a late vintage Edelbrock manifold (which...

Jumping back and forth between the '84 intake fabrication and getting my '51 Chevy P/U on the road (after too many decades). I've got the original '84 engine sitting in the pickup, and I'm about to put a mechanical fuel pump on it. This engine didn't have an old style fuel pump plate on the...

Before I go to all the trouble of drilling the heads on some 10-24 machine screws I thought I'd ask for some input. I'm fabricating a lower height intake manifold upper section to allow me to reinstall the stock hood on my '84. Years ago I had to put a raised cowl hood on it to clear the turbo...

I've had my (lighter replacement) aluminum LCA crossmember 90% finished for quite some time, but I'm not comfortable with the regular method of attaching the lower control arms (clamping/bending the crossmember tabs/flanges to prevent the steel bushing from rotating around the attachment bolts)...

A poster (elsewhere) asked me if I still have power steering on my car, given its lighter weight compared to its original factory bulk. I said yes, but a manual rack (no pump weight) fitting my car is out of my budget. But that got me thinking. What is the steering response like (and any...

...trying to modify a junkyard rear swaybar (off an old Oldsmobile FWD car) to fit my '69. I need to bend the arms inward a bit more (they're about 15* outward from a right angle, and I need to bend them so they're about 15* inward), but it's a tubular bar (metric, about .600" diameter and .100"...

Am kicking around swapping out the heater hose section from the water pump to the expansion tank, and replacing that piece with some 3/8" rubber fuel line. (This reduces the amount and weight of minimally productive coolant just sitting in that connection.) I was going to use high pressure (fuel...

Just curious. Is it possible to open the rear window hatch manually? I've got the battery out, and I'm too damn lazy to put it in just to pop the rear window/hatch open. Or do I need to just quit bitching and temporarily hook the battery up with some jumper cables? Thanks!

After years of avoiding the weight of an electric fan and heavier alternator, I've got a combo I think I can live with. (I prefer a lightweight mechanical fan setup for the simplicity, low weight, reliability, and stock look, but with my front mounted steering rack, the mechanical fan location...

Putting my distributor back together, and I noticed an item (most probably the result of the stupidity or carelessness of my youth) that I'm trying to fix. I have too much shaft endplay, so I need to find/make an appropriate thickness shim, but what I'm "scratching" my head about is if I lost a...

The lightweight radiator I put in the '69 has a cooler for an automatic transmission. Right now I've just got it capped off. Is there anything I could use that for? It seems too hot for a p/s cooler application, and using it for an engine oil cooler seems risky/complex and inefficient. Not a...

I currently have a homemade air box that seals up to the L88 hood rear opening. The concept works (efficiency = ?), and with some string lengths hanging down over the hood rear opening I can see the strings being pushed inward at speeds above about 15 mph. I'd sure like to do some efficiency...

I've had the original (long block) engine wrapped up in storage for several years while I put track mileage on some non-numbers matching engines. I occasionally unwrap it (every couple years), squirt some more oil in the cylinders and turn the crank over a bit. I unwrapped it today, took a peek...

I'm currently modifying the UCA mounts to allow a bit more dynamic caster and camber. While I've got things apart I'm kicking around running the coilovers upside down (if it will package worth a darn). They're gas shocks, so the position shouldn't be an issue (correct me if I'm wrong), and there...

While I'm tied up with some mechanical/fabrication stuff in the garage, I've been kicking around some future projects. I want to pull out some more battery weight this year (I'm currently running a 16# 360 CA battery), but I'd like to do it a smarter way rather than just putting in something...
