    Best Cordless Tools?

    I've had good service from a Bosch 18-volt 3/8" driver/drill and 3/8" impact wrench. I've owned the driver/drill and two lithium ion batteries for approx 15 years. Bought the impact wrench a few years later -- tool only, no batteries. Those original batteries still hold a charge a lot longer...

    Lunati street master

    If your main things is a lopey idle, then that cam should do it. It's similar to the old 350hp/327 cam but with a tighter LSA for engines with lower compression than 11:1. What's your static compression ratio? I'm guessing the cam would like at least 9.5:1. With less than that, your lope...

    Cut New Dash Pad For Speaker Install?

    I used a dash pad from Cheyenne Pickups that had perforations for a center dash speaker, which let me use this 4x10 RetroSound speaker. Certainly not great, but much better than OE, and would be a good combo with some 6x9s mounted in enclosures behind the doors...

    New TH350 shift linkage from Lokar

    I bought one of those kits several years ago when I converted an 82 C10 to TH350 from 3-speed manual. I also used a rebuilt 82 tilt/auto trans column. First problem: It was not a straight shot from the lever on the column to the trans shift stud, so I had to bend the Lokar rod. Next: The...

    Looks like a survivor. Job One: replace that rear bumper.:)

    how long does polyurethane last?

    I replaced worn suspension bushings with poly on 69 and 82 pickups and a 55 Chevy car. I did not notice a stiffer ride over tar strips, etc. What I did notice was (1) better steering response with poly control arm and sway bar bushings, (2) less engine movement with poly motor mounts, and (3)...

    Camshaft flexibility for 1978 350

    The CL08-503-8 cam is for 1986-up factory roller cam blocks, also known as "one piece main seal" blocks. https://www.speedwaymotors.com/COMP-Cams-CL08-503-8-Xtreme-Energy-Hyd-Roller-Camshaft-Kit-GM-305-350,222838.html Comp probably has a "retro-fit" cam for earlier blocks, but they get very...

    Summit Carb Install Gone Very Wrong

    Looks like simply a bad casting. As for the carb, a buddy of mine has run the 600cfm version for around 8-10 years now. It worked great out of the box, and all I had to do was adjust idle mixture and speed. It's based on the old Holley 4010 series, with supposedly a few improvements. I...

    383 vortec high compression

    Last thing you want to do is lower compression by adding thicker gasket. That can easily make matters worse! I didn't read all the advice above, but want to add that what you need is pistons with a D-dish, like these...

    4L80E or GV Overdrive for my '90 Suburban?

    R2500 = 2wd, right? If so, why not take the simple route and change the ring and pinion to something like a 3.42, or whichever ratios are available for a 3/4 ton diff? RPMs would drop around 17%, and you'd still have converter slip to get you moving in first gear. I know my old SWB square...

    my whacked column rebuild

    Sounds like the OP is well on his way, but this is for future reference: I bought a very nice rebuilt column from Wayne at GM Tilt back around 2015. His after the sale support was great. I highly recommend him. http://gmtiltsteeringcolumn.com/

    Overheating “slightly” and infrequently

    Some electrical gauges will display different temps depending on voltage. For example, with ignition on, engine not running, and battery at 12 volts, a gauge might read 180. But fire up the engine, voltage jumps to 14 volts, and the gauge might read 190 or more. If you have a voltmeter, you...

    rear drums not workin

    Did you use new shoes on drums that have been turned? If so, the arc of the shoes will have a smaller radius than the arc of the drum. That causes only the center 1/3 or less (!) of the linings to make contact with the drum. Back in the day, shops would "arc in" the shoes so the entire lining...

    Need advice--Camshaft degree issue (maybe??)

    Just read your last post. If LSA is 107 (214 at the crank), then "straight up" would be 107 ATDC. So with intake center line at 102 ATDC, that's 5 degrees advanced, as you said. But using a stock timing set you would still get 5 degrees advanced, not 9 degrees. Where am I wrong here? Is...

    Need advice--Camshaft degree issue (maybe??)

    Actually, that's probably perfect! I know that most, if not all, of Comp's small block cams are drilled to be 4 degrees advanced with a stock timing set. So I'm assuming the same is true for your Olds cam. Good article here...

    Well crap

    They're not cheap, but I really like the Melling Select pumps. I have used the #10552 small block pump a couple of times with the #12558 3/4" diameter bolt-on pickup, which you can adjust for pan clearance. Description: Melling's years of experience are apparent in these Performance oil pumps...

    I'am Going To Build A Smooth Idle 427

    That should be a fantastic torque monster! Where did you get the camshaft and lifters? And is the manifold NOS? If not, how did you get it so clean? Super clean shop you have there!

    Setting Pinion Depth

    Yes, using the original shim gets the job done most of the time. I would think pinion depth measurement only works if the depth is marked on the pinion.

    New brake upgrade on the frame off restore

    Very nice! I put Wilwood's least expensive 4-piston calipers and 11.75" discs on the front of a 55 Chevy and absolutely loved them. Even with a manual master cylinder (also Wilwood) the car probably stopped better than 55s with cheap power brake conversions.

    Just fyi - I dyed my carpet - it came out great

    Back in the day I bought a black carpet that after a few years started to turn a reddish color where the sun hit it. Cleaned it and then sprayed it with Duplicable black dye. That was at least 10 years ago and it's still 100% black.

    Which brakes are right

    Which brakes are right

    Yes, base trucks got JB1 (manual) or JB3 (power) with 1.04" thick rotors. A step up was JD3 with 1.29" rotors. Calipers and inner wheel bearings were also different. Pads were the same. Did I get this right, Keith?

    Easy to install trans cooler and temp gauge recommendations

    My 69 C10's B&M light-duty aux cooler has been installed since 2002. I used high pressure trans cooler hose with fuel injection-type clamps. It's certainly not as robust as steel lines with flare fittings, but my point is it's not cheap hose that will easily crack. I probably need to replace...

    Cluster install for DUMMIES...help

    I spent a lot of time making sure I got mine right when installing a new universal wiring harness. This might help somewhat: Also, I found this Painless manual to be very helpful on everything electrical: https://www.painlessperformance.com/Manuals/20205.pdf
